Source Inject

A source generator for C# that uses Roslyn (the C# compiler) to allow you to generate your dependencies injection during compile time. By doing this you avoid using reflection and services are automatically registered.

How to use it

Install it and add an attribute to the classes you want injected in your service provider, like so:

[Inject]
public class ExampleService
{
    private readonly AnotherService anotherService;

    public ExampleService(AnotherService anotherService) =>
        this.anotherService = anotherService;

    public string GetValue() => anotherService.Value;
}

[Inject(ServiceLifetime.Singleton)]
public class AnotherService
{
    public string Value => "Hello World!";
}

As you can see above you can define the lifetime. The default lifetime is transient. You can also use the following attributes:

  • InjectSingletonAttribute
  • InjectScopedAttribute
  • InjectTransientAttribute

The last one is the same as using Inject without any arguments.

You then have to call the Discover method so these classes are found and the source is generated. You can then require them using constructor injection or service locator, for example:

var services = new ServiceCollection();
services.Discover();
var serviceProvider = services.BuildServiceProvider();
var exampleService = serviceProvider.GetRequiredService<ExampleService>();

You can also discover services in other assemblies. To be able to do this you have to call the method DiscoverIn<AssemblyName> or <AssemblyName>Discoverer.Discover(services). If your assembly name has dots . in them they will be replaced by underscore _.

All these methods (Discover et all) and attributes will be generated in your project for you.

You can see the generated code using Visual Studio. See here for an example.
