I want to develop an extension for VS2010 that will allow me make some additional features to syntax-highlighting.
I installed the SDK, how do I start from?
You might check out
http://code.msdn.microsoft.com/ookLanguage
which has a syntax highlighter in "OokTokenTag.cs" in the C# sample. You do have to parse a whole block of text, of course, but this is not too hard.
