Visual Studio 2010 and TFS connection: "The ServicePointManager does not support proxies with the https scheme."

Using the beta version of Visual Studio 2010, and trying to connect to a Team Foundation Server, you may find that you get the error message:

 

"The ServicePointManager does not support proxies with the https scheme."

 

You'll only get this of course if you are trying to connect using HTTPS / port 443. The workaround seems to be some reg fixes which tell the TFS client to bypass the proxy.

 

Aaron Block's MSDN blog seems to have the answer to this:
