Ling.AutoInject

Ling.AutoInject provides attribute-driven registration helpers and integrates with a source generator to emit IServiceCollection extension methods that register services discovered via attributes at compile time.

Features

  • Attributes: SingletonService, ScopedService, TransientService for simple, declarative registration.
  • Optional service typing and keyed registration support.
  • Configurable generated method name, host class and namespace through an assembly-level AutoInjectConfig attribute.
  • Service replacement: use Replace = true to replace existing registrations instead of skipping when a service is already registered.
  • Class-level customization via AutoInjectExtensionsAttribute for control over method generation behavior, including optional IConfiguration parameter support.
  • Complementary analyzers to surface common mistakes and invalid configurations in the IDE.

Installation

via .NET CLI:

dotnet add package Ling.AutoInject

via Package Manager Console:

Install-Package Ling.AutoInject

Usage

  1. Decorate implementation types:

    using Ling.AutoInject;

[SingletonService]
public class MyService { }

[ScopedService(typeof(IFoo))]
public class MyService : IFoo { }

[TransientService(ServiceKey = "k1")]
public class MyService { }

  2. (Optional) Configure generator output naming:

    [assembly: Ling.AutoInject.AutoInjectConfig(
    MethodName = "AddCustomServices",
    ClassName = "ServiceExtensions",
    Namespace = "MyNamespace")]

  3. Call the generated extension in Program / Startup:

    services.Add[MyAssembly]Services();
// or
services.AddCustomServices();

Notes

  • If no service type is specified, the implementation type is registered as itself.
  • If a service type is specified, the generator registers the mapping from service interface to implementation.
  • Keyed registration requires the DI Abstractions package to support keyed APIs; analyzers warn when unsupported.

Advanced features

Replace existing registrations

Use the Replace property to replace existing service registrations instead of using TryAdd methods:

[SingletonService(typeof(IFoo), Replace = true)]
public class MyService : IFoo { }

This generates services.Replace(ServiceDescriptor.Singleton<IFoo, MyService>()) instead of services.TryAddSingleton<IFoo, MyService>().

Using AutoInjectExtensionsAttribute

Instead of using the assembly-level AutoInjectConfig, you can decorate a static partial class with AutoInjectExtensionsAttribute for more control:

using Ling.AutoInject;

namespace MyNamespace
{
    [AutoInjectExtensions(MethodName = "AddCustomServices")]
    public static partial class MyServiceExtensions { }
}

This generates a partial class with the specified method name in the same namespace as the decorated class.

Including IConfiguration

Use IncludeConfiguration = true to generate a method that accepts an IConfiguration parameter:

[AutoInjectExtensions(MethodName = "AddCustomServices", IncludeConfiguration = true)]
public static partial class MyServiceExtensions { }

This generates:

public static IServiceCollection AddCustomServices(this IServiceCollection services, IConfiguration configuration)
{
    // ...
    AddAdditionalServices(services, configuration);
    return services;
}

static partial void AddAdditionalServices(IServiceCollection services, IConfiguration configuration);

You can implement the AddAdditionalServices partial method to add custom service registrations that require configuration.

Planned features

  • Options binding: future work will add attribute-driven registration and configuration binding for options classes (IOptions<T>), including section binding.

Contributing

  • PRs and issues welcome. Include tests for analyzer/generator changes.
