C# Extension methods in .NET 2.0

Question

I have found several links to methods of making extension methods work in .NET2.0 (The moth, Discord & Rhyme, Stack Overflow). I have also heard vaguely from a colleague

Answer 1

I would recommend Discord and Rhyme because it providing meaningful constraints for how the attribute is supposed to be applied.

1. It can only be applied to methods
2. You can only apply it once
3. The attribute cannot be inherited
