C# Source Generator to automatically register dependencies in Microsoft Dependency Injection Service Collection

Hey there, the name's Patrick 👋

autoregisterinject's Issues

vNext roadmap

Tracking issue for vNext

This list represents issues and ideas to be implemented in vNext. Below will not necessarily be released at the same time, but rather over a longer term.

• Add ability to ignore interfaces
• Add ability to auto register hosted services

Add GitHub Action pipeline for automated releases

Add GitHub Actions to build and release to Nuget.

• Add GitVersion for versioning
• Add GitHub Action pipeline for main release
• Add GitHub Action pipeline to validate PRs

Support Generated Interfaces

We are actually generating our interfaces (we're actually using multiple generators together).

[AutoInterface]
[AutoConstruct]
public partial class ItemsService : IItemsService
{
   // removed for brevity
}

However, AutoRegisterInject isn't finding our generated interfaces.

Both:

[AutoInterface]
[AutoConstruct]
[RegisterTransient]
public partial class ItemsService : IItemsService
{
   // removed for brevity
}

And:

[AutoInterface]
[AutoConstruct]
[RegisterTransient(typeof(IItemsService))]
public partial class ItemsService : IItemsService
{
   // removed for brevity
}

Produce:

// <auto-generated>
//     Automatically generated by AutoRegisterInject.
//     Changes made to this file may be lost and may cause undesirable behaviour.
// </auto-generated>
using Microsoft.Extensions.DependencyInjection;
public static class AutoRegisterInjectServiceCollectionExtension
{
    public static Microsoft.Extensions.DependencyInjection.IServiceCollection AutoRegisterFromServices(this Microsoft.Extensions.DependencyInjection.IServiceCollection serviceCollection)
    {
        return AutoRegister(serviceCollection);
    }

    internal static Microsoft.Extensions.DependencyInjection.IServiceCollection AutoRegister(this Microsoft.Extensions.DependencyInjection.IServiceCollection serviceCollection)
    {
        serviceCollection.AddTransient<Services.ItemsService>();
        return serviceCollection;
    }
}

Not sure whether it will be possible to address this due to the use of multiple generators. Was hoping to not have to chose one generator in favor of another when they do not compete in equivalent features.

Support keyed services

New attributes to register as keyed services, string to indicate their key.

Keyed services

Hi is there any plans for adding support for keyed services?

Support TryAdd methods

Instead of using methods such as AddTransient and AddSingleton, can it use TryAddTransient and TryAddSingleton (including the other possible lifetimes)? Or possibly make it configurable?

Doesn't register as abstract service, only as implementation.

I have this class:

public sealed class Settings
{
   public required string ConnectionString { get; init; }
}

I have a fluent validator like so:

[RegisterTransient(typeof(IValidator<Settings>))]
public class SettingsValidator : AbstractValidator<Settings>
{
   public SettingsValidator() =>
      RuleFor(static settings => settings.ConnectionString)
        .NotEmpty()
        .WithMessage($"{nameof(Settings.ConnectionString)} must have a valid connection string.")
        .Must(BeAbleToConnect)
        .WithMessage($"{nameof(Settings.ConnectionString)} is not valid or cannot connect to the database.");

   static bool BeAbleToConnect(string connectionString)
   {
      try
      {
         using SqlConnection connection = new (connectionString);

         connection.Open();

         return true;
      }
      catch { return false; }
   }
}

I expect it to register like so:

serviceCollection.AddSingleton<IValidator<Settings>, SettingsValidator>();

However, it always registers it like this instead:

// <auto-generated>
//     Automatically generated by AutoRegisterInject.
//     Changes made to this file may be lost and may cause undesirable behaviour.
// </auto-generated>
using Microsoft.Extensions.DependencyInjection;
public static class AutoRegisterInjectServiceCollectionExtension
{
    public static Microsoft.Extensions.DependencyInjection.IServiceCollection AutoRegisterFromMyProject(this Microsoft.Extensions.DependencyInjection.IServiceCollection serviceCollection)
    {
        return AutoRegister(serviceCollection);
    }

    internal static Microsoft.Extensions.DependencyInjection.IServiceCollection AutoRegister(this Microsoft.Extensions.DependencyInjection.IServiceCollection serviceCollection)
    {
        serviceCollection.AddTransient<MyProject.SettingsValidator>();
        return serviceCollection;
    }
}
