[VS/TFS] 連接TFS出現無法切換伺服器，忙碌中訊息/unable to switch server at this time, team explorer is busy

說明：
使用VS 2008安裝Team Explorer 2008與向上相容TFS 2010套件連接TFS 2010，在新增伺服器時，輸入TFS URL後，出現該錯誤訊息。


解法：
將輸入的URL最後的反斜線拿掉即可。例：http://[ServerName]:8080/tfs/，移除/。
因為Team Explorer 2008比較舊，無法處理/，造成無法連線。
可參閱[1]：

Warning:  Although the Admin Console displays the URL with a final slash, "/", the older clients do not take handle the slash and will not connect.

It is possible to connect to the default Team Project Collection by providing the server name only. This method is limited, as it only allows connection to one of the Team Project Collections in a TFS Instance.
