How to change a Visual Studio project type?

Question

I finally figured out that Visual Studio keeps track of how you create a project (in other words which project template you select initially) and filters your options later

Answer 1

In visual studio the project type is stored inside the .csproj XML file as GUID. You have to change the GUID to define the new project type you want.

check http://www.mztools.com/Articles/2008/MZ2008017.aspx for some of the availbale GUIDs
