Hi,
I tacked my question onto the bottom of another thread (http://social.msdn.microsoft.com/Forums/en-US/tfsgeneral/thread/8adcab44-0994-4ff8-8ea7-50636b7bd62f), but have had no response.
I've recently run into an issue where VS2012 will not connect to an external TFS. I sit behind a proxy and when VS2012 tries to connect, I get a 407 - Proxy Authentication required error. VS2010 installed on the same PC does not have any problem connecting.
I also tried connecting using the Excel Add-In and it has the same problem.
Using the default Devenv.exe.config, VS2012 will quite happily collect news and connect to Nuget and download extensions.
I tried making the changes suggested here, but the only effect it has is to prevent VS2012 from collecting news and extensions, but does not enable connection to the external TFS.
<system.net><defaultProxyuseDefaultCredentials="true"enabled="true"><proxyusesystemdefault="True"/></defaultProxy><settings><ipv6enabled="true"/><servicePointManagerexpect100Continue="false"/></settings></system.net>
What else can I try to make this work? I am sure that for a while, VS2012 did happily connect and perhaps since I installed the latest update, it now refuses to do so. Could that have any bearing on the case?
Thanks
Graham
