DependencyInjection.SourceGenerator.LightInject 1.2.1

DependencyInjection.SourceGenerator.LightInject

Register services using attributes instead of registering in code.

Usage

Add the "Register" attribute to the class you want to register. The attribute takes a type and a lifetime. The type is the type you want to register and the lifetime is the lifetime of the service. The lifetime is optional and defaults to Transient.

var services = new ServiceCollection();
services.AddMyProject();

### LightInject

```csharp
[Register(ServiceName = "ServiceName", Lifetime = Lifetime.Singleton)]
public class ExampleService : IExampleService
{
	public string GetExample()
	{
		return "Example";
	}
}

public interface IExampleService
{
	string GetExample();
}

Generates a class CompositionRoot

public class CompositionRoot : ICompositionRoot
{
	public static void Compose(IServiceRegistry serviceRegistry)
	{
		serviceRegistry.Register<IExampleService, ExampleService>("ServiceName", new PerContainerLifetime());
	}
}

If you already have a class CompositionRoot defined, the generated class will be made partial. Remeber to make your CompositionRoot partial as well. It will also call a method RegisterServices on the existing CompositionRoot class (this must be defined).

public partial class CompositionRoot : ICompositionRoot
{
	public static void Compose(IServiceRegistry serviceRegistry)
	{
		RegisterServices(serviceRegistry);
		serviceRegistry.Register<IExampleService, ExampleService>("ServiceName", new PerContainerLifetime());
	}
}

The final existing CompositionRoot class must look like this:

public partial class CompositionRoot
{
	public void RegisterServices(IServiceRegistry serviceRegistry)
	{
		// Register services here
	}
}

Lifetime

The lifetime is an enum with the following values:

• Transient
• Scoped
• Singleton
