TFS 2008 and VS2010 Beta1

Some users have tried to connect to TFS 2008 using VS2010 Beta1, and they have got the following error:

TF31001: Cannot connect to Team Foundation Server at xxx.com. The server returned the following error: The ServicePointManager does not support proxies with the https scheme.

The problem is that the default value to BypassProxyOnLocal (proxy server should be bypassed for local addresses) in TFS 2008 is false, while in 2010 the default value is true, resolving a performance problem experienced by some customers.

If you want to solve your problem just follow this post:
