Generating class DI registration from attributes

This is how you can use AutoRegisterInject .

The code that you start with is

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

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net7.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="AutoRegisterInject" Version="1.2.1" />
    <PackageReference Include="Microsoft.Extensions.DependencyInjection" Version="7.0.0" />
  </ItemGroup>
	<PropertyGroup>
		<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
		<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
	</PropertyGroup>
</Project>

The code that you will use is

// See https://aka.ms/new-console-template for more information
using AutoRegisterInjectDemo;
using Microsoft.Extensions.DependencyInjection;

Console.WriteLine("Hello,World!");
ServiceCollection sc = new();
sc.AutoRegisterFromAutoRegisterInjectDemo();
var b=sc.BuildServiceProvider();
var con = b.GetRequiredService<DatabaseCon>();
var db=b.GetRequiredService<IDatabase>();
db.Open();

namespace AutoRegisterInjectDemo;

[RegisterScoped]
internal class Database : IDatabase
{
    private readonly DatabaseCon con;

    public Database(DatabaseCon con)
    {
        this.con = con;
    }
    public void Open()
    {
        Console.WriteLine($"open {con.Connection}");
    }

}

namespace AutoRegisterInjectDemo
{
    internal interface IDatabase
    {
        void Open();
    }
}

namespace AutoRegisterInjectDemo;

[RegisterSingleton]
internal class DatabaseCon
{
    public string? Connection { get; set; }
}
