Aspect Injector is an attribute-based framework for creating and injecting aspects into your .net assemblies.

> dotnet add package AspectInjector

• Compile-time injection
• Injecting Before, After and Around targets
• Injecting into Methods, Properties, Events
• Injecting Interface implementaions
• Supports any project that can reference netstandard2.0 libraries
• Debugging support
• Roslyn analyzers for your convenience (only c# currently)

Check out samples and docs

• .NetCore runtime 2.1.6+

• Unsafe methods are not supported and are silently ignored.
• You cannot inject code around constructors. Such attempts are silently ignored. You can since 2.2.1!
• Until Nuget v5 you need to refrecence AspectInjector into every project in your solution. Thus,

    if VisualStudio >= 2019 && CoreSDK >= 2.1.602
        no worries about references
    else 
        reference AspectInjector directly to projects where aspects are defined or used

[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() { }
