Tropa Chat Messaging Server with .NET 8 Minimal API and SignalR

This project implements a real-time chat messaging server using ASP.NET 8 Minimal API, SignalR, and an in-memory cache for temporary data storage (for demonstration purposes). The code adheres to an N-Tier architecture and incorporates authentication and authorization mechanisms.

---

Prerequisites:

• .NET 8 SDK (https://dotnet.microsoft.com/en-us/download)
• Basic understanding of ASP.NET Minimal API, SignalR, N-Tier architecture, and caching

---

Tech Stack:

• ASP.NET 8 Minimal API
• SignalR
• Caching library (choose one based on preference): https://learn.microsoft.com/en-us/dotnet/api/system.runtime.caching.memorycache?view=dotnet-plat-ext-8.0 - Microsoft.Extensions.Caching.Memory
• Optional: Entity Framework Core (for future persistence layer): https://learn.microsoft.com/en-us/ef/core/get-started/overview/install

---

Features:

• Real-time chat functionality using SignalR
• User authentication and authorization (implementation details omitted for brevity)
• N-Tier architecture separates concerns (Models, Controllers, Hubs, Services, Repositories)
• In-memory cache acts as a temporary database (for demo)
• (Optional) Future integration with a persistent database (e.g., SQL Server, CosmosDb) using Entity Framework Core

---

Running the application:

• Restore NuGet packages: dotnet restore
• Run the server: dotnet run
• Access the application using a web client that supports SignalR (e.g., localhost:5000/)

---

Notes

• This is a basic implementation for demonstration purposes.
• Authentication and authorization details are omitted for brevity. You'll need to implement them based on your chosen approach (e.g., JWT, IdentityServer).
• The in-memory cache is for demo only. Consider a persistent database for production environments.
• Error handling and logging are not included in this basic example.

---

Further Enhancements:

• Implement user presence and typing indicators.
• Integrate private messaging functionality.
• Add file upload capabilities.
• Persist chat history in a database.
