Some time ago I started to write a class with some C# extension methods, adding more methods over time. I first uploaded the file to the webspace of my blog, but I think this is getting too complicated to mantain, which makes it harder than required to post new versions.
So I’ve put the code on github: https://github.com/jcoder/jCsharpExtensions
