How to write Visual Studio addin for custom text coloring?

Question

Hello.

I need to write a visual studio 2005+ addin for custom coloring of some file format (for example, i need to highlight all words "test" in files that has ".test" extension). Is it any good tutorials available? MSDN help is very general and huge :(. Preferable language is C#, but VB or C++ will do too :).
