I want a .net solution for AOP?-Collection of common programming errors

There are plenty of AOP-ish solutions for .NET – PostSharp, Unity Interception, Spring.NET AOP, LOOM.NET to name just a few.

They differ in the way of weaving (applying aspects to base code) – generally it can be done in IL or at runtime. They differ also in syntax, capabilities, way of creating/fetching your objects, performance, learning curve etc. You have to decide what is important for you and then we can maybe suggest any solution.

What I suggest you first is to read the “AOP on .NET” article at PostSharp website.
