This is a problem that I haven’t come across before, but it looks like others have:
TF30330: Team Explorer cannot write to the project list configuration file. Free up space on the local hard disk. If the problem persists, contact the administrator for your computer to confirm that your user account has appropriate permissions to write to the file.
The simple fix is to:
- Open a Visual Studio Command Prompt
- Run: devenv /resetuserdata
If you want to know what the undocumented (and subsequently unsupported) /resetuserdata switch does, have a read of the section on this Visual Studio IDE Tips and Tricks post.
You’re probably still wondering where to find the actual “project list configuration file” that it complains about?
This file specifies which servers & project are visible in Team Explorer.
