Application Status Samples Status


> dotnet add package AspectInjector


  • Compile-time injection - works with Blazor and AOT
  • Injecting Before, After and Around (wrap) Methods, Constructors, Properties and Events
  • Injecting Interface implementations
  • Supports any project that can reference netstandard2.0 libraries, see here
  • Debugging support
  • Roslyn analyzers for your convenience (only c# currently)
  • Can work DI/IoC frameworks #166

Check out samples and docs


  • (semi-optional) Nuget 5.0+ for transient build feature. All modern versions of VS and dotnetsdk have it. (If you still use project.json for some reason - make sure you add AspectInjector to all projects in the solution)
  • (optional) For analyzers to work in VSCode, don't forget to enable "omnisharp.enableRoslynAnalyzers": true

Known Issues / Limitations

  • Unsafe methods are not supported and are silently ignored.

Simple advice

Create an aspect with simple advice:
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:
public void Calculate() 

$ dotnet run
Calling 'Calculate' method...

Simple mixin

Create an aspect with mixin:
public interface IInitializable
    void Init();

public class Initializable : IInitializable, Attribute
    public void Init()
Use it:
public class Target

var target = new Target() as IInitializable;
$ dotnet run
