In an earlier entry (Format C# or .NET Code for your Blog or Website), I linked to manoli.net/csharpformat as a great web site for formatting C# or .NET Code for you blog.  Clint Rutkas pointed out that Windows Live Writer has a plug-in that uses Jean-Claude Manoli's library:  Insert Code for Windows Live Writer.  So far, I haven't been using Windows Live Writer although everyone recommends it;  now I have a compelling reason to check it out!
