Solution to connecting to TFS using HTTPS over the Internet from behind ISA

This problem it seams is to do with the way Visual Studio 2010 connects to your TFS server over HTTPS. The default value for “BypassProxyOnLocal” in Visual Studio 2008 was “False”, but it has been changed to “True” for Visual Studio 2010 Beta 1. It should be noted that this is currently a Beta 1 workaround and this behaviour may be updated for Beta 2 and RTM.

You can fix this by adding the following registry keys and restarting Visual Studio 2010:

You need to add a “RequestSettings” key to both of the following location that contains a string value pair of “BypassProxyOnLocal=’False’”.

32bit OS Key Locations:

HKEY_LOCAL_MACHINESOFTWAREMicrosoftTeamFoundationServer10.0RequestSettings

HKEY_LOCAL_MACHINESOFTWAREMicrosoftVisualStudio10.0TeamFoundationRequestSettings

64bit key locations:

HKEY_LOCAL_MACHINESOFTWAREWow6432NodeMicrosoftTeamFoundationServer10.0RequestSettings

HKEY_LOCAL_MACHINESOFTWAREWow6432NodeMicrosoftVisualStudio10.0TeamFoundationRequestSettings

You can find out more on the “How to: Change the BypassProxyOnLocal Configuration ” documentation on MSDN.
