Instead of manually regenerating your EF Core models in Visual Studio, this package: - -- ✅ **Automatically builds** your SQL Server Database Project to a DACPAC -- ✅ **OR connects directly** to your database via connection string -- ✅ **Runs EF Core Power Tools** CLI during `dotnet build` -- ✅ **Generates DbContext and entities** from your database schema -- ✅ **Intelligently caches** - only regenerates when schema or config changes -- ✅ **Works everywhere** - local dev, CI/CD, Docker, anywhere .NET runs -- ✅ **Zero manual steps** - true database-first development automation - -### Architecture - -The package orchestrates a MSBuild pipeline with these stages: - -1. **Resolve** - Locate database project and configuration files -2. **Build** - Compile SQL Project to DACPAC (if needed) -3. **Stage** - Prepare configuration and templates -4. **Fingerprint** - Detect if regeneration is needed -5. **Generate** - Run `efcpt` to create EF Core models -6. **Compile** - Add generated `.g.cs` files to build - ---- - -## 📦 SDK vs PackageReference - -JD.Efcpt.Build offers two integration approaches: - -### JD.Efcpt.Sdk (SDK Approach) - -Use the SDK when you want the **cleanest possible setup**: - -```xml - - - net8.0 - - -``` - -**Best for:** -- Dedicated EF Core model generation projects -- The simplest, cleanest project files - -### JD.Efcpt.Build (PackageReference Approach) - -Use the PackageReference when adding to an **existing project**: - -```xml - - - -``` - -**Best for:** -- Adding EF Core generation to existing projects -- Projects already using custom SDKs -- Version management via Directory.Build.props - -Both approaches provide **identical features** - choose based on your project structure. - -See the [SDK documentation](docs/user-guide/sdk.md) for detailed guidance. - ---- - -## ✨ Features - -### Core Capabilities - -- **🔄 Incremental Builds** - Smart fingerprinting detects when regeneration is needed based on: - - Library or tool version changes - - Database schema modifications - - Configuration file changes - - MSBuild property overrides (`EfcptConfig*`) - - Template file changes - - Generated file changes (optional) -- **🎨 T4 Template Support** - Customize code generation with your own templates -- **📁 Smart File Organization** - Schema-based folders and namespaces -- **🔧 Highly Configurable** - Override namespaces, output paths, and generation options via MSBuild properties -- **🌐 Multi-Schema Support** - Generate models across multiple database schemas -- **📦 NuGet Ready** - Enterprise-ready package for production use - -### Build Integration - -- **Automatic DACPAC compilation** from SQL Projects -- **Project discovery** - Automatically finds your database project -- **Template staging** - Handles T4 templates correctly (no duplicate folders!) -- **Generated file management** - Clean `.g.cs` file naming and compilation -- **Rebuild detection** - Triggers regeneration when `obj/efcpt` is deleted - ---- - -## 📦 Installation - -### Prerequisites - -- **.NET SDK 8.0+** (or compatible version) -- **EF Core Power Tools CLI** (`ErikEJ.EFCorePowerTools.Cli`) - **Not required for .NET 10.0+** (uses `dnx` instead) -- **SQL Server Database Project** that compiles to DACPAC: - - **[Microsoft.Build.Sql](https://github.com/microsoft/DacFx)** - Microsoft's official SDK-style SQL Projects (uses `.sqlproj` extension), cross-platform - - **[MSBuild.Sdk.SqlProj](https://github.com/rr-wfm/MSBuild.Sdk.SqlProj)** - Community SDK for SQL Projects (uses `.csproj` or `.fsproj` extension), cross-platform - - **Traditional SQL Projects** - Legacy `.sqlproj` format, requires Windows/Visual Studio with SQL Server Data Tools - -### Quick Start with Templates (Recommended) - -The easiest way to get started is using the project template: - -```bash -# Install the template package (one-time) -dotnet new install JD.Efcpt.Build.Templates - -# Create a new project -dotnet new efcptbuild --name MyDataProject -``` - -This creates a fully configured SDK project with: -- JD.Efcpt.Sdk as the project SDK (cleanest setup) -- EF Core dependencies -- Sample `efcpt-config.json` with best practices -- Helpful README with next steps - -**Visual Studio users:** After installing the templates, you can create new projects via **File > New > Project** and search for **"EF Core Power Tools SDK Project"**. - -### Manual Installation - -#### Step 1: Install the Package - -Add to your application project (`.csproj`): - -```xml - - - - -``` - -Or install via .NET CLI: - -```bash -dotnet add package JD.Efcpt.Build -dotnet add package Microsoft.EntityFrameworkCore.SqlServer -``` - -#### Step 2: Install EF Core Power Tools CLI - -**Option A: Global Tool (Quick Start)** - -```bash -dotnet tool install --global ErikEJ.EFCorePowerTools.Cli --version "10.*" -``` - -**Option B: Local Tool (Recommended for Teams/CI)** - -```bash -# Create tool manifest (if not exists) -dotnet new tool-manifest - -# Install as local tool -dotnet tool install ErikEJ.EFCorePowerTools.Cli --version "10.*" -``` - -Local tools ensure everyone on the team uses the same version. -

Installation - -### 2.1 Add the NuGet package - -Add a package reference to your application project (the project that should contain the generated DbContext and entity classes): - -```xml - - - -``` - -Or enable it solution-wide via `Directory.Build.props`: - -```xml - - - - - -``` - -### 2.2 Install EF Core Power Tools CLI - -`JD.Efcpt.Build` drives the EF Core Power Tools CLI (`efcpt`). You must ensure the CLI is available on all machines that run your build. - -Global tool example: - -```powershell -# PowerShell - dotnet tool install -g ErikEJ.EFCorePowerTools.Cli -``` - -Local tool (recommended for shared/CI environments): - -```powershell -# From your solution root - dotnet new tool-manifest - dotnet tool install ErikEJ.EFCorePowerTools.Cli --version "10.*" -``` - -By default the build uses `dotnet tool run efcpt` when a local tool manifest is present, or falls back to running `efcpt` directly when it is globally installed. These behaviors can be controlled using the properties described later. - -### 2.3 Prerequisites - -- .NET SDK 8.0 or newer. -- EF Core Power Tools CLI installed as a .NET tool (global or local). -- A SQL Server Database Project that compiles to a DACPAC: - - **[Microsoft.Build.Sql](https://github.com/microsoft/DacFx)** - Microsoft's official SDK-style SQL Projects (uses `.sqlproj` extension), cross-platform - - **[MSBuild.Sdk.SqlProj](https://github.com/rr-wfm/MSBuild.Sdk.SqlProj)** - Community SDK for SQL Projects (uses `.csproj` or `.fsproj` extension), cross-platform - - **Traditional SQL Projects** - Legacy `.sqlproj` format, requires Windows with SQL Server Data Tools / build tools components - ---- - -## 3. High-level architecture - -`JD.Efcpt.Build` wires a set of MSBuild targets into your project. When `EfcptEnabled` is `true` (the default), the following pipeline runs as part of `dotnet build`: - -1. **EfcptResolveInputs** – locates the SQL Project and resolves configuration inputs. -2. **EfcptQuerySchemaMetadata** *(connection string mode only)* – fingerprints the live database schema. -3. **EfcptEnsureDacpac** *(SQL Project mode only)* – builds the SQL Project to a DACPAC if needed. -4. **EfcptStageInputs** – stages the EF Core Power Tools configuration, renaming rules, and templates into an intermediate directory. -5. **EfcptComputeFingerprint** – computes a fingerprint across the DACPAC (or schema fingerprint) and staged inputs. -6. **EfcptGenerateModels** – runs `efcpt` and renames generated files to `.g.cs` when the fingerprint changes. -7. **EfcptAddToCompile** – adds the generated `.g.cs` files to the `Compile` item group so they are part of your build. - -The underlying targets and tasks live in `build/JD.Efcpt.Build.targets` and `JD.Efcpt.Build.Tasks.dll`. - ---- - -## 4. Minimal usage - -### 4.1 Typical solution layout - -A common setup looks like this: - -- `MyApp.csproj` – application project where you want the EF Core DbContext and entities. -- `Database/Database.sqlproj` (or `Database.csproj` if using MSBuild.Sdk.SqlProj) – SQL Project that produces a DACPAC. -- `Directory.Build.props` – optional solution-wide configuration. - -### 4.2 Quick start - -1. Add `JD.Efcpt.Build` to your application project (or to `Directory.Build.props`). -2. Ensure a SQL Project exists somewhere in the solution that builds to a DACPAC. -3. Optionally copy the default `efcpt-config.json` from the package (see below) into your application project to customize namespaces and options. -4. Run: - -```powershell - dotnet build -``` - -On the first run the build will: - -- Build the SQL Project to a DACPAC. -- Stage EF Core Power Tools configuration. -- Run `efcpt` to generate DbContext and entity types. -- Place generated code under the directory specified by `EfcptGeneratedDir` (by default under `obj/efcpt/Generated` in the sample tests). - -Subsequent builds will only re-run `efcpt` when the DACPAC or staged configuration changes. - ---- - -## 5. Configuration via MSBuild properties - -The behavior of the pipeline is controlled by a set of MSBuild properties. You can define these in your project file or in `Directory.Build.props`. - -### 5.1 Core properties - -- `EfcptEnabled` (default: `true`) - - Master on/off switch for the entire pipeline. - -- `EfcptOutput` - - Intermediate directory used to stage configuration and compute fingerprints. - - If not set, a reasonable default is chosen relative to the project. - -- `EfcptGeneratedDir` - - Directory where generated C# files are written. - - Used by `EfcptGenerateModels` and `EfcptAddToCompile`. - -- `EfcptSqlProj` - - Optional override for the path to the Database Project (`.sqlproj`). - - When not set, `ResolveSqlProjAndInputs` attempts to discover the project based on project references and solution layout. - -- `EfcptConnectionString` - - Optional explicit connection string override. - - When set (or when a connection string is resolved from configuration files), the pipeline runs in **connection string mode**: - - `EfcptEnsureDacpac` is skipped. - - `EfcptQuerySchemaMetadata` runs and its schema fingerprint is used in incremental builds instead of the DACPAC content. - -- `EfcptAppSettings` - - Optional `appsettings.json` path used to resolve connection strings. - -- `EfcptAppConfig` - - Optional `app.config` / `web.config` path used to resolve connection strings. - -- `EfcptConnectionStringName` (default: `DefaultConnection`) - - Connection string name/key to read from configuration files. - -- `EfcptProvider` (default: `mssql`) - - Database provider identifier. - - Supported values: `mssql`, `postgres`, `mysql`, `sqlite`, `oracle`, `firebird`, `snowflake`. - -- `EfcptConfig` - - Optional override for the EF Core Power Tools configuration file (defaults to `efcpt-config.json` in the project directory when present). - -- `EfcptRenaming` - - Optional override for the renaming configuration (defaults to `efcpt.renaming.json` in the project directory when present). - -- `EfcptTemplateDir` - - Optional override for the template directory (defaults to `Template` in the project directory when present). - -- `EfcptSolutionDir` - - Root directory used when probing for related projects, if automatic discovery needs help. - -- `EfcptProbeSolutionDir` - - Controls whether solution probing is performed. Use this if your layout is non-standard. - -- `EfcptSolutionPath` - - Optional solution file path used as a fallback when discovering the SQL project. - -- `EfcptLogVerbosity` - - Controls task logging (`minimal` or `detailed`). - -### 5.2 Tool resolution properties - -These properties control how the `RunEfcpt` task finds and invokes the EF Core Power Tools CLI: - -- `EfcptToolMode` - - Controls the strategy used to locate the tool. Common values: - - `auto` – use a local tool if a manifest is present, otherwise fall back to a global tool. - - `tool-manifest` – require a local tool manifest and fail if one is not present. - - Any other non-empty value forces the global tool path. - -- `EfcptToolPackageId` - - NuGet package ID for the CLI. Defaults to `ErikEJ.EFCorePowerTools.Cli`. - -- `EfcptToolVersion` - - Requested CLI version or version range (for example, `10.*`). - -- `EfcptToolRestore` - - When `true`, the task may restore or update the tool as part of the build. - -- `EfcptToolCommand` - - The command to execute when running the tool (defaults to `efcpt`). - -- `EfcptToolPath` - - Optional explicit path to the `efcpt` executable. When set, this takes precedence over `dotnet tool run`. - -- `EfcptDotNetExe` - - Optional explicit path to the `dotnet` host used for tool invocations and `.sqlproj` builds. - -### 5.3 Fingerprinting and diagnostics - -- `EfcptFingerprintFile` - - Path to the fingerprint file produced by `ComputeFingerprint`. - -- `EfcptStampFile` - - Path to the stamp file written by `EfcptGenerateModels` to record the last successful fingerprint. - -- `EfcptDumpResolvedInputs` - - When `true`, `ResolveSqlProjAndInputs` logs the resolved inputs to help diagnose discovery and configuration issues. - ---- - -## 6. Configuration files and defaults - -The NuGet package ships default configuration assets under a `Defaults` folder. These defaults are used when you do not provide your own, and they can be copied into your project and customized. - -### 6.1 `efcpt-config.json` - -`efcpt-config.json` is the main configuration file for EF Core Power Tools. The version shipped by this package sets sensible defaults for code generation, including: - -- Enabling nullable reference types. -- Enabling `DateOnly`/`TimeOnly` where appropriate. -- Controlling which schemas and tables are included. -- Controlling namespaces, DbContext name, and output folder structure. - -Typical sections you might customize include: - -- `code-generation` – toggles for features such as data annotations, T4 usage, or using `DbContextFactory`. -- `names` – default namespace, DbContext name, and related name settings. -- `file-layout` – where files are written relative to the project and how they are grouped. -- `replacements` and `type-mappings` – table/column renaming rules and type overrides. - -You can start with the default `efcpt-config.json` from the package and adjust these sections to match your conventions. - -### 6.2 `efcpt.renaming.json` - -`efcpt.renaming.json` is an optional JSON file that contains additional renaming rules for database objects and generated code. Use it to: - -- Apply custom naming conventions beyond those specified in `efcpt-config.json`. -- Normalize table, view, or schema names. - -If a project-level `efcpt.renaming.json` is present, it will be preferred over the default shipped with the package. - -### 6.3 Template folder - -The package also ships a `Template` folder containing template files used by EF Core Power Tools when T4-based generation is enabled. - -If you need to customize templates: - -1. Copy the `Template` folder from the package into your project or a shared location. -2. Update `EfcptTemplateDir` (or the corresponding setting in `efcpt-config.json`) to point to your customized templates. - -During a build, the `StageEfcptInputs` task stages the effective config, renaming file, and template folder into `EfcptOutput` before running `efcpt`. - ---- - -## 7. Examples - -### 7.1 Basic project-level configuration - -Application project (`MyApp.csproj`): - -```xml - - - net8.0 - - - - - - - - - ..\Database\Database.sqlproj - - -``` - -Place `efcpt-config.json` and (optionally) `efcpt.renaming.json` in the same directory as `MyApp.csproj`, then run `dotnet build`. Generated DbContext and entities are automatically included in the compilation. - -### 7.2 Solution-wide configuration via `Directory.Build.props` - -To enable the pipeline across multiple application projects, you can centralize configuration in `Directory.Build.props` at the solution root: - -```xml - - - - true - - - $(MSBuildProjectDirectory)\obj\efcpt\ - $(MSBuildProjectDirectory)\obj\efcpt\Generated\ - - - tool-manifest - ErikEJ.EFCorePowerTools.Cli - 10.* - - - - - - -``` - -Individual projects can then override `EfcptSqlProj`, `EfcptConfig`, or other properties when they diverge from the solution defaults. - -### 7.3 CI / build pipeline integration - -No special steps are required beyond installing the prerequisites. A typical CI job includes: - -```powershell -# Restore tools (if using a local manifest) - dotnet tool restore - -# Restore and build the solution - dotnet restore - dotnet build --configuration Release -``` - -On each run the EF Core models are regenerated only when the DACPAC or EF Core Power Tools inputs change. - -> **💡 Tip:** Use [Microsoft.Build.Sql](https://github.com/microsoft/DacFx) or [MSBuild.Sdk.SqlProj](https://github.com/rr-wfm/MSBuild.Sdk.SqlProj) to build DACPACs on Linux/macOS CI agents. Traditional `.sqlproj` files require Windows agents with SQL Server Data Tools components. - ---- - -## 8. Troubleshooting - -### 8.1 Generated models do not appear - -- Confirm that `EfcptEnabled` is `true` for the project. -- Verify that the `.sqlproj` can be built independently (for example, by opening it in Visual Studio or running `dotnet msbuild` directly). -- If discovery fails, set `EfcptSqlProj` explicitly to the full path of the `.sqlproj`. -- Increase logging verbosity by setting `EfcptLogVerbosity` to `detailed` and inspect the build output. -- Check that `EfcptGeneratedDir` exists after the build and that it contains `.g.cs` files. - -### 8.2 DACPAC build problems - -- Ensure that either `msbuild.exe` (Windows) or `dotnet msbuild` is available. -- For **traditional SQL Projects**: Install the SQL Server Data Tools / database build components on a Windows machine. -- For **cross-platform builds**: Use [Microsoft.Build.Sql](https://github.com/microsoft/DacFx) or [MSBuild.Sdk.SqlProj](https://github.com/rr-wfm/MSBuild.Sdk.SqlProj) which work on Linux/macOS/Windows without additional components. -- Review the detailed build log from the `EnsureDacpacBuilt` task for underlying MSBuild errors. - -### 8.3 `efcpt` CLI issues - -- Run `dotnet tool list -g` or `dotnet tool list` (with a manifest) to confirm that `ErikEJ.EFCorePowerTools.Cli` is installed. -- If using a local tool manifest, set `EfcptToolMode` to `tool-manifest` to enforce its use. -- If needed, provide an explicit `EfcptToolPath` to the `efcpt` executable. -- Make sure the CLI version requested by `EfcptToolVersion` is compatible with your EF Core version. - -### 8.4 Inspecting inputs and intermediate outputs - -- Set `EfcptDumpResolvedInputs` to `true` to log how the `.sqlproj`, config, renaming file, and templates are resolved. -- Inspect the directory specified by `EfcptOutput` to see: - - The staged `efcpt-config.json`. - - The staged `efcpt.renaming.json`. - - The staged `Template` folder used by EF Core Power Tools. - - The fingerprint and stamp files that control incremental generation. - -### 8.5 Test-only environment variables - -This repository’s own tests use a few environment variables to simulate external tools and speed up test runs: - -- `EFCPT_FAKE_BUILD` – simulates building the DACPAC without invoking a real database build. -- `EFCPT_FAKE_EFCPT` – simulates the `efcpt` CLI and writes deterministic sample output. -- `EFCPT_TEST_DACPAC` – points tests at a specific DACPAC. - -These variables are intended for internal tests and should not be used in production builds. - ---- - -## 9.

SDK Version Check (`CheckSdkVersion`) + +**Purpose:** Validates that the JD.Efcpt.Build package version matches expectations. + +**Inputs:** +- `PackageVersion` - The current package version +- `ExpectedSdkVersion` - The expected SDK version (optional) + +**Outputs:** +- `SdkVersionCheckPassed` - Boolean indicating if check passed + +**Behavior:** +- If `ExpectedSdkVersion` is not specified, check always passes +- Logs a warning (not error) if versions don't match +- This is a non-breaking check to help identify version mismatches + +### 2. Input Resolution (`ResolveSqlProjAndInputs`) + +**Purpose:** Resolves the DACPAC file, configuration files, and connection string based on the project's configuration. + +**Resolution Strategy:** + +The task follows a multi-tier resolution chain for each input type: + +#### DACPAC Resolution + +1. **Explicit DacpacPath** - If `EfcptDacpac` is set, use it directly +2. **SQL Project Reference** - If `EfcptSqlProj` is set, locate the `.dacpac` in its output directory +3. **Auto-Discovery** - Search for `.sqlproj` files in: + - Same directory as the .csproj + - Parent directories (up to solution root) + - Adjacent directories + +#### Configuration File Resolution + +1. **Explicit Path** - If `EfcptConfig` is set, use it +2. **Convention-Based** - Search for `efcpt-config.json` in: + - Project directory + - Solution directory + +#### Connection String Resolution + +Supports multiple input sources: + +1. **Direct Connection String** - `EfcptConnectionString` property +2. **appsettings.json** - Reads `ConnectionStrings:DefaultConnection` or `ConnectionStrings:Default` +3. **app.config** (Framework projects) - Reads from `` section +4. **User Secrets** (.NET Core+) - Reads from user secrets if configured + +**Outputs:** +- `ResolvedDacpacPath` - Absolute path to the DACPAC file +- `ResolvedConfigPath` - Absolute path to the efcpt-config.json file (if found) +- `ResolvedConnectionString` - Connection string for database access (if using connection string mode) +- `ResolvedSqlProjectPath` - Path to the .sqlproj file (if found) + +### 3. DACPAC Build Verification (`EnsureDacpacBuilt`) + +**Purpose:** Ensures that if a SQL project is referenced, its DACPAC is built and up-to-date. + +**Inputs:** +- `SqlProjectPath` - Path to the .sqlproj file +- `ExpectedDacpacPath` - Where the DACPAC should be + +**Behavior:** +- Checks if DACPAC exists at the expected location +- Compares timestamps of .sqlproj and .dacpac +- Logs a warning if DACPAC is missing or stale +- Does NOT automatically build the SQL project (respects build orchestration) + +### 4. Fingerprint Computation (`ComputeFingerprint`) + +**Purpose:** Computes a deterministic hash representing all inputs to the code generation process. + +**Components of the Fingerprint:** + +The fingerprint is a XXH64 hash of: + +1. **DACPAC Content** + - Full binary content of the .dacpac file + - Includes schema definitions, table structures, columns, indexes + +2. **Configuration File** + - Content of efcpt-config.json (if present) + - Includes all override settings + +3. **Template Files** + - Content of custom T4 templates (if used) + - Includes EntityType.t4, DbContext.t4, etc. + +4. **Tool Version** + - Version of the efcpt CLI tool being used + - Ensures regeneration when tool is updated + +5. **Connection String Schema Fingerprint** (when using connection string mode) + - Schema metadata from the live database + - Includes table names, column definitions, indexes + - Normalized to ensure deterministic ordering + +**Output:** +- `GeneratedFingerprint` - 16-character hexadecimal hash + +**Algorithm:** +```csharp +fingerprint = XXH64( + File.ReadAllBytes(dacpacPath) + + File.ReadAllBytes(configPath) + + Directory.GetFiles(templateDir) + .OrderBy(f => f) + .SelectMany(f => File.ReadAllBytes(f)) + + Encoding.UTF8.GetBytes(toolVersion) + + Encoding.UTF8.GetBytes(schemaFingerprint) +) +``` + +### 5. Incremental Build Check + +**Purpose:** Compares the computed fingerprint against the last successful build to determine if regeneration is needed. + +**Fingerprint Storage:** +- Stored in `$(IntermediateOutputPath).efcpt/fingerprint.txt` +- Plain text file containing the hex fingerprint +- Persisted across builds for comparison + +**Decision Logic:** +``` +if fingerprint.txt exists AND + contents match GeneratedFingerprint: + Skip code generation (use cached files) +else: + Proceed with code generation + Write new fingerprint.txt +``` + +### 6. Code Generation (`RunEfcpt`) + +**Purpose:** Invokes the Entity Framework Core Power Tools CLI to generate model files. + +**Tool Resolution Strategy:** + +The task supports multiple modes for running the efcpt tool: + +#### 1. Explicit Tool Path Mode + +```xml +/path/to/efcpt.exe +``` + +Directly executes the specified executable. + +#### 2. DNX Mode (.NET 10+) + +For projects targeting .NET 10.0 or later: + +```bash +dotnet dnx ErikEJ.EFCorePowerTools.Cli --yes -- [args] +``` + +- Automatically used when: + - Target framework is `net10.0` or later + - .NET 10 SDK is installed + - `dnx` command is available +- Benefits: + - No tool installation required + - Uses SDK-provided tool execution + - Faster startup + +#### 3. Local Tool Manifest Mode + +```bash +dotnet tool run efcpt -- [args] +``` + +- Used when `.config/dotnet-tools.json` is found +- Searches parent directories for the manifest +- Automatically runs `dotnet tool restore` if `EfcptToolRestore=true` + +#### 4. Global Tool Mode + +```bash +dotnet tool update --global ErikEJ.EFCorePowerTools.Cli +efcpt [args] +``` + +- Fallback mode when no manifest is found +- Updates/installs the global tool if `EfcptToolRestore=true` +- Executes the global `efcpt` command + +**Execution:** + +```bash +efcpt reverse-engineer \ + --dacpac /path/to/project.dacpac \ + --config /path/to/efcpt-config.json \ + --output-dir /path/to/generated \ + --namespace MyProject.Models +``` + +**Environment Variables:** +- `EFCPT_TEST_DACPAC` - Forwarded from MSBuild environment (for testing) + +### 7. File Renaming (`RenameGeneratedFiles`) + +**Purpose:** Renames generated files with `.g.cs` extension to clearly mark them as generated code. + +**Pattern:** +``` +Product.cs → Product.g.cs +Customer.cs → Customer.g.cs +NorthwindContext.cs → NorthwindContext.g.cs +``` + +**Rationale:** +- Clear visual indicator of generated code +- Follows .NET convention (similar to `.g.i.cs` for XAML) +- Enables `.gitignore` patterns like `*.g.cs` +- IDE integration (some IDEs treat `.g.cs` specially) + +### 8. Output Categorization (`SplitOutputs`) + +**Purpose:** Categorizes generated files into MSBuild item groups for proper compiler integration. + +**Output Item Groups:** + +```xml + + + + + + + +``` + +**Why Separate DbContext?** +- Enables conditional inclusion +- Supports custom compilation settings +- Allows for different code analysis rules + +### 9. Configuration Serialization (`SerializeConfigProperties`) + +**Purpose:** Serializes MSBuild properties into a JSON file for consumption by the efcpt tool. + +**Generated File:** `$(IntermediateOutputPath).efcpt/build-properties.json` + +**Content:** +```json +{ + "ProjectDir": "/path/to/project", + "IntermediateOutputPath": "obj/Debug/net8.0/", + "TargetFramework": "net8.0", + "RootNamespace": "MyProject", + "AssemblyName": "MyProject", + "Configuration": "Debug" +} +``` + +## Incremental Build Behavior + +### When Code IS Regenerated + +Code generation occurs when: + +1. **DACPAC changes** - Schema modifications detected +2. **Configuration changes** - efcpt-config.json modified +3. **Template changes** - Custom T4 templates updated +4. **Tool version changes** - efcpt CLI updated +5. **First build** - No previous fingerprint exists +6. **Clean build** - Intermediate output cleaned +7. **Connection string schema changes** - Live database schema modified + +### When Code is NOT Regenerated + +Code generation is skipped when: + +1. **Fingerprint matches** - All inputs unchanged since last build +2. **Rebuild without changes** - Manual rebuild with identical inputs + +### Benefits of Incremental Builds + +- **Faster builds** - Skips expensive schema analysis and code generation +- **Better caching** - Works with MSBuild's incremental build system +- **CI/CD friendly** - Deterministic, cacheable outputs +- **Developer experience** - Quick iteration when models unchanged + +## Integration with MSBuild + +### Target Ordering + +The pipeline integrates into MSBuild's standard target graph: + +``` +BeforeBuild + ↓ +CheckSdkVersion + ↓ +ResolveSqlProjAndInputs + ↓ +EnsureDacpacBuilt + ↓ +ComputeFingerprint + ↓ +StageEfcptInputs + ↓ +RunEfcpt + ↓ +RenameGeneratedFiles + ↓ +SplitOutputs + ↓ +SerializeConfigProperties + ↓ +CoreCompile (standard MSBuild) +``` + +### Dependency Management + +The pipeline properly declares dependencies: + +```xml + +``` + +**MSBuild Optimization:** +- `Inputs` and `Outputs` attributes enable MSBuild's own incremental logic +- Complements the fingerprint-based approach +- Ensures proper build ordering + +## Configuration Override System + +The pipeline supports a sophisticated override system: + +### Application Point + +Configuration overrides are applied: + +1. **After** efcpt generates the base configuration +2. **Before** code generation executes + +### Override Sources + +```json +{ + "Overrides": { + "Names": { + "DbContext": "CustomContext", + "Namespace": "Custom.Namespace" + }, + "FileLayout": { + "OutputPath": "Generated/Models", + "SplitDbContext": true + }, + "Preferences": { + "UseDataAnnotations": false, + "UseDatabaseNames": true + } + } +} +``` + +### Application Strategy + +The `ApplyConfigOverrides` task: + +1.

Mission-critical production systems (for initial pilot) +- ❌ Projects with unusual schema requirements +- ❌ Teams under tight deadlines + +#### 1.2 Initial Setup + +**Option 1: Create from template (quickest start)** + +```bash +# Install templates package +dotnet new install JD.Efcpt.Build.Templates + +# Create new project from template +dotnet new efcptbuild -n MyProject -o src/MyProject + +# Template creates: +# - MyProject.csproj (configured with JD.Efcpt.Sdk) +# - efcpt-config.json (standard configuration) +``` + +**Option 2: Use as MSBuild SDK (for existing projects)** + +```xml + + + + +``` + +**Option 3: Use as NuGet package** + +```xml + + + + + +``` + +#### 1.3 Create Standard Configuration + +Create a baseline `efcpt-config.json` (or use the one generated by the template): + +```json +{ + "names": { + "root-namespace": "YourCompany.PilotProject", + "dbcontext-name": "ApplicationDbContext", + "dbcontext-namespace": "YourCompany.PilotProject.Data", + "entity-namespace": "YourCompany.PilotProject.Data.Entities" + }, + "code-generation": { + "use-nullable-reference-types": true, + "use-date-only-time-only": true, + "enable-on-configuring": false, + "use-t4": false + }, + "file-layout": { + "output-path": "Models", + "output-dbcontext-path": ".", + "use-schema-folders-preview": true, + "use-schema-namespaces-preview": true + } +} +``` + +#### 1.4 Measure Success Metrics + +Track: +- **Build time reduction** (incremental builds) +- **Developer satisfaction** (survey) +- **Bugs related to model sync** (reduction expected) +- **Time to onboard new developers** (should decrease) + +### Phase 2: Standardization (4-8 weeks) + +**Goal:** Establish organization-wide standards based on pilot learnings. + +#### 2.1 Create Configuration Standards + +**Establish conventions:** + +```jsonc +// company-efcpt-config-template.json +{ + "names": { + // Standard: DbContext name derived from project/database + // Note: JD.Efcpt.Build auto-derives from SQL project or DACPAC name + "dbcontext-name": "ApplicationDbContext", + // Standard: Align with project's root namespace + // Note: JD.Efcpt.Build uses RootNamespace MSBuild property by default + "root-namespace": "YourCompany.Data" + }, + "file-layout": { + // Standard: Always use "Models" folder for generated entities + "output-path": "Models", + // Standard: Split DbContext for clarity + "split-dbcontext-preview": true + }, + "code-generation": { + // Standard: Use fluent API (not data annotations) + "use-data-annotations": false, + // Standard: Use C# conventions (not database names) + "use-database-names": false, + // Standard: Never include connection strings in code + "enable-on-configuring": false, + // Standard: Use nullable reference types + // Note: JD.Efcpt.Build derives this from project's setting + "use-nullable-reference-types": true + } +} +``` + +#### 2.2 Create Internal Documentation + +**Document:** +- Why the organization uses JD.Efcpt.Build +- Step-by-step setup guide (with screenshots) +- Configuration standards +- Common troubleshooting steps +- Who to contact for help + +**Example structure:** +``` +internal-wiki/ +├── why-jd-efcpt-build.md +├── setup-guide.md +├── configuration-standards.md +├── troubleshooting.md +└── faq.md +``` + +#### 2.3 Create Project Templates + +**Option A: Extend existing templates** + +```bash +# Create custom template package +dotnet new template create --name YourCompany.AspNet.Template +``` + +**Include:** +- Pre-configured `efcpt-config.json` +- Standard connection string in `appsettings.json` +- Example SQL project reference +- Note: Generated files go to `obj/efcpt/Generated/` by default, which is already excluded by standard `.gitignore` + +**Option B: Scripted setup** + +```bash +#!/bin/bash +# setup-efcpt.sh +PROJECT_NAME=$1 +ROOT_NAMESPACE=$2 + +echo "Setting up JD.Efcpt.Build for $PROJECT_NAME..." + +# Create standard efcpt-config.json +cat > efcpt-config.json < + + + ..\company-efcpt-configs\base-config.json + +``` + +### Strategy: MSBuild Directory.Build.props + +**Centralize common properties:** + +```xml + + + + + tool-manifest + ErikEJ.EFCorePowerTools.Cli + 10.* + + +``` + +**Projects automatically inherit:** + +```xml + + + + + + + ../Database/Database.dacpac + + +``` + +## Multi-Project Best Practices + +### Pattern 1: Shared SQL Project +

+- Regular audits of project configurations + +### Challenge: Build Performance in Large Monorepos + +**Problem:** Many projects regenerating models slows builds. + +**Solution:** +- Use fingerprinting (should be automatic) +- Cache `obj/` directories in CI/CD +- Consider splitting very large schemas +- Use incremental builds (`dotnet build --no-restore`) + +### Challenge: Resistance to Adoption + +**Problem:** Some teams reluctant to change existing workflows. + +**Solution:** +- Demonstrate time savings with metrics +- Highlight reduced bugs from automated sync +- Start with enthusiastic early adopters +- Provide excellent support during transition +- Allow gradual migration (not all-at-once) + +### Challenge: Training at Scale + +**Problem:** Hard to train 100+ developers individually. + +**Solution:** +- Record training sessions for async learning +- Create interactive sandbox environments +- Champion network for peer-to-peer help +- Office hours for live questions +- Comprehensive written documentation + +## Success Metrics + +### Key Performance Indicators (KPIs) + +**Adoption Metrics:** +- % of projects using JD.Efcpt.Build +- % of developers active
