Is there a developers guide some where to help get started with .net & VS?

I am using SolidWorks 2006 and I have the 2005 professional edition of Visual Studio (VS for short). I did see that in my VS that I did have com references for solidworks, but I am not sure how to get started. Is there a developers guide linked some where? I also tried to run or look at an example in the API documents but they would not open in my VS, so I am a bit stuck at the moment.

Thanks for any assistance,
Robert
