“I need an extension to do X… I’ll just code it up quickly…” Wait! Before you go directly to code, check out ExtensionMethod.NET

ExtensionMethod.NET

“ExtensionMethod.NET is a database of C# 3.0 and Visual Basic 2008 extension methods. It contains many user-rated extension methods that will expand your code library immediately.

Extension methods add functionality to existing classes and allow you to expand the .NET framework. This way your favorite functions integrate seamlessly into the framework. For more information about extension methods visit the C# 3.0 and Visual Basic 2008 MSDN Library pages.

A very cool looking site indeed…
