Visual Studio Project Convertor
It would really be a daunting experience after downloading a Visual Studio .NET project file and your Visual Studio refusing it to open complaining that it has been designed for another version of the product. I came across a tool called VSConvert from CodeProject, which I would like to share the information with my readers and which I hope would greatly help in converting project files across .NET Framework (1.0 and 1.1). Check out this tool from CodeProject VSConvert page.
Currently, conversion of project files to 2.0 framework is possible using Visual Studio 2005 itself as the IDE pops up a wizard. However, the reverse might not be possible since there are a lot of changes from 1.1 to 2.0 version of the framework.
