Known Issues / Limitations

Simple advice

Create an aspect with simple advice:

[Aspect(Scope.Global)]
[Injection(typeof(LogCall))]
public class LogCall : Attribute
{
    [Advice(Kind.Before)] // you can have also After (async-aware), and Around(Wrap/Instead) kinds
    public void LogEnter([Argument(Source.Name)] string name)
    {
        Console.WriteLine($"Calling '{name}' method...");   //you can debug it	
    }
}

Use it:

[LogCall]
public void Calculate() 
{ 
    Console.WriteLine("Calculated");
}

Calculate();

Result:

$ dotnet run
Calling 'Calculate' method...
Calculated

Simple mixin

Create an aspect with mixin:

public interface IInitializable
{
    void Init();
}

[Aspect(Scope.PerInstance)]
[Injection(typeof(Initializable))]
[Mixin(typeof(IInitializable))]
public class Initializable : IInitializable, Attribute
{
    public void Init()
    {
        Console.WriteLine("Initialized!");
    }
}

Use it:

[Initializable]
public class Target
{ 
}

var target = new Target() as IInitializable;
target.Init();

Result:

$ dotnet run
Initialized!
