Aspect Injector is a framework for creating and injecting aspects into your .net assemblies.

> dotnet add package AspectInjector

• Compile-time injection
• Injection Before, After and Around targets
• Injection into Methods, Properties, Events
• Injection Interface implementaions
• Works with any framework/runtime that supports netstandard2.0
• Debugging support
• Roslyn analyzers for your convenience (only c# currently)

Check out samples and docs

• .NetCore runtime 2.1.6+

• If you use Visual Studio earlier than 2019 you'll need to reference AspectInjector into every project when you want your injections work. Since VS2019 it is fixed.
• Unsafe methods are not supported and are silently ignored.
• You cannot inject code around constructors. Such attempts are silently ignored.

[Aspect(Scope.Global)]
[Injection(typeof(LogCall))]
class LogCall : Attribute
{
    [Advice(Kind.Before)]
    public void LogEnter([Argument(Source.Name)] string name)
    {
        Console.WriteLine($"Calling {name}");   //you can debug it	
    }
}

[LogCall]
public void Calculate() { }
