RSCG – AutoInvoke.Generator
 
 

Finding all implementation of an interface/class and invoke them.

This is how you can use AutoInvoke.Generator .

The code that you start with is

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net8.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="AutoInvoke.Generator" Version="0.0.9">
      <PrivateAssets>all</PrivateAssets>
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
    </PackageReference>
  </ItemGroup>
	<PropertyGroup>
		<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
		<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
	</PropertyGroup>

</Project>

The code that you will use is

using AutoAdd;

RemoteCollection rc=new();
foreach(var item in rc.loaders)
{
    item.Execute();
}

namespace AutoAdd;
partial class RemoteCollection
{
    public List<IRemoteCommand> loaders = new ();

    public RemoteCollection()
    {
        LoadLoaders();
    }
    [AutoInvoke.FindAndInvoke]
    public void LoadLoaders<T>() where T : IRemoteCommand,new()
    {
        loaders.Add(new T());
    }
    
}

namespace AutoAdd;
internal class PCRemote : IRemoteCommand
{
    public void Execute()
    {
        Console.WriteLine("start PC");
    }
}

namespace AutoAdd;
internal class TVRemote : IRemoteCommand
{
    public void Execute()
    {
        Console.WriteLine("start TV");
    }
}

The code that is generated is

// <auto-generated/>
#nullable enable

namespace AutoInvoke;
[System.AttributeUsage(System.AttributeTargets.Method,Inherited = false,AllowMultiple = true)]
[System.Diagnostics.Conditional("AutoNotifyGenerator_DEBUG")]
internal sealed class FindAndInvokeAttribute : System.Attribute

    public FindAndInvokeAttribute()
