Hi Daniel,

In order for the "Source Control" folder to be displayed under your
connected project area, you have to make sure that your current source
control plug-in is pointing to "Jazz Source Control".

To verify, follow the steps below:
In Microsoft Visual Studio, click Tools > Options

From the Options dialog, select Source Control > Plug-in Selection
Ensure Jazz Source Control is selected from the Current source control
plug-in drop-down list.

Hope this helps!
