Here are the steps for repro:

1. Open TFS connected project
2. Under the project tab, click the ‘Open’ button on the TFS toolbar
3. The Open dialog then opens to a Connect to TFS pane with the TFS connection details. Click Connect.
4. The user then has to navigate to their local directory and choose the TFS connected project.

There should be a way to save the project location so that he won’t have to navigate to it every time he opens it.
