Here's the deal. I had a computer with Visual Studio 2003, 2005, and 2008 all installed with .Net 1.1, .NET 2.0, and .NET 3.5. I was able to open projects in all three versions of Visual Studio. I just got a new computer (same OS, same model laptop, same everything) and installed all of those versions of VS, with the addition of Visual Studio 2010 and the .NET 4 framework. When I attempt to open one of my previously working applications in VS2005 I receive the following error:
Unable to read the project file '[project name].vbproj'...The imported project [project location] was not found. Confirm that the path in the <Import> declaration is correct, and that the file exists on disk.
Does this have anything to do with where / how I installed Visual Studio 2005?
