What are the requirements to open Document module 4.00.00 project or solution. I have tried both VS2005 and VS2003.

With 2005 I get project type is not supported by this installation

With 2003 I got the message that the file was created by a newer version...so I am assuming it should be opened with VS2005 .net2.0 framework. Anything else I need to install to the environment. Should I open the dotnetnuke solution and add the project?

I had this same configuration issue when I was extending the functionality of the calendar. It took me a day plus to get a successful pre development build and then only a couple of hours to write my code and build the new dll. I, and maybe others, would appreciate a short concise txt doc that just spells out what is needed to work with the source code of any particular module (if it exists and I am just missing it then ignore this rant).
