I added some files to my Solution and then deleted after some code tests. Now, the items are still in Excluded Changes of Team Explorer. How can I refresh Visual Studio Excluded Changes panel so that the removed items go away?
Depending on your version of Visual Studio you will have a pending changes window (probably under the Team Explorer tab). Just select the deleted file, open the context menu and select Undo...
