Unable to add data connection. Key not valid for use in specified state.

I found a relevant bug report (FDBK18994) in
http://lab.msdn.microsoft.com/productfeedback/default.aspx
the MSDN Product Feedback Center.

I solved the problem by renaming the VisualStudio folders in
..\Application Data\Microsoft
..\Local Settings\Application Data\Microsoft
to VisualStudioXXX

I had installed Visual Studio Team System (after I got the CD-ROMs in the mail) on top the express editions of Visual C# and Visual Web Developer. I did not experience any problems for several weeks. After renaming the two directories, I have a cleaner looking GUI that has Team Explorer and Class View tabs. I even have File-New-Project. Now I understand why the labs and webcasts have looked different from my version.

This solution worked for me.

1. Open the registry

2. Rename [HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\8.0]

To [HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\8.0back]

3. Restart Visual Studio
