WinForms application

This example demonstrates the creation of a WinForms application in the pure DI paradigm using the Pure.DI code generator.

The composition definition is in the file Composition.cs. Remember to define all the necessary composition roots, for example, this could be a main form such as FormMain:

using Pure.DI;
using static Pure.DI.Lifetime;

namespace WinFormsAppNetCore;

partial class Composition
{
    private void Setup() => DI.Setup()
        .Root<Program>(nameof(Root))

        .Bind().As(Singleton).To<FormMain>()
        .Bind().As(Singleton).To<ClockViewModel>()
        .Bind().To<ClockModel>()
        .Bind().As(Singleton).To<Ticks>()

        // Infrastructure
        .Bind().To<DebugLog<TT>>()
        .Bind().To<WinFormsDispatcher>();
}

A single instance of the Composition class is defined in the Main method of the Program.cs file:

namespace WinFormsAppNetCore;

public class Program(FormMain formMain)
{
    [STAThread]
    public static void Main()
    {
        ApplicationConfiguration.Initialize();
        using var composition = new Composition();
        composition.Root.Run();
    }

    private void Run() => Application.Run(formMain);
}

The project file looks like this:

<Project Sdk="Microsoft.NET.Sdk">
    ...
    <ItemGroup>
        <PackageReference Include="Pure.DI" Version="2.3.6">
            <PrivateAssets>all</PrivateAssets>
            <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
        </PackageReference>
    </ItemGroup>

</Project>
