dotnet add package SharpAspect
SharpAspect is an AOP (Aspect-Oriented Programming) package for .Net
It depends on Castle.Core DynamicProxy. Currently only supports method and property interception.
Take advantage of run-time interception for your next project.
Check the wiki page for more samples and documentation.
