Saspect

AOP (Aspect Oriented Programming) using dotnet source generator.

Including extensions for Autofac, but any implementation that calls the generated code would do.

Usage example, logging all calls to console:

Saspect/Saspect.Test/SampleTest.cs

Lines 8 to 45 in 6e61f79

	public class MyService
	{
	[Log]
	public virtual void MyMethod()
	{
	}
	}
	public class LogAttribute() : AspectAttribute(typeof(LogAspect));
	public class LogAspect : IAspect
	{
	public void OnBeforeInvocation(InvocationInfo invocation)
	{
	Console.WriteLine($"{invocation.Method.Name} is invoked");
	}
	public void OnAfterInvocation(Exception exception, InvocationInfo invocation)
	{
	Console.WriteLine($"{invocation.Method.Name} exited");
	}
	}
	public class SampleTest
	{
	[Test]
	public void ShouldLogMethodCallToConsole()
	{
	var builder = new ContainerBuilder();
	builder.RegisterType<AspectInterceptor>();
	builder.RegisterType<LogAspect>().As<IAspect>();
	builder.RegisterType<MyService>().ApplyAspects();
	var container = builder.Build();
	var target = container.Resolve<MyService>();
	target.MyMethod();
	}
