TFS Error: “Source Control - Unable to Access Database”

Question

I am currently using TFS with Visual Studio 2010 Ultimate and getting this error when I try to open up my solution:

The associated source control plug-in is no

Answer 1

I was able to eliminate the error by performing File | Source Control | Open from Source Control. You will be asked whether to overwrite existing files; answer "yes".
(You should, of course, back up your source code first.)

Note, this was on VS2008; I have not tried it on VS2010.

Answer 2

I had to reset my Visual Studio configuration and cache by following the below steps:

Delete the contents from the following folders

C:\Users\<>\AppData\Local\Microsoft\Team Foundation
C:\Users\<>\AppData\Local\Microsoft\VisualStudio
C:\Users\<>\AppData\Local\Microsoft\VSCommon

Go to the Visual Studio IDE folder in command prompt and Run the following command "devenv /resetuserdata" from the Visual Studio IDE folder.

Typical location for 62 bit: C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE
Typical location for 32 bit: C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE

I found these steps in the article below:

If you have problems with TFS or Visual Studio flush the user cache … or not?

Answer 3

Thank you guys for the suggestions. I tried all of those and neither of them worked. What I ended up having to do was create a new User Account on my machine, delete the original folder to where I had my mappings and Redo the Get Process for my project and everything worked fine. I guess something must have been corrupt on my User Account.
