  • Hi, this list is nice. I am Microsoft developer and I’ve recently noticed that regular expressions in Visual Studio 2008 are slightly different then the standard. Not nice of course but this is the reality. Maybe the tool for checking the Visual Studio Regex expression could be nice?

    I have wrote something more about it. (http://blog.goyello.com/2009/08/22/do-it-like-a-pro-–-visual-studio-find-and-replace/)
