Answer 1

Using IDE configuration:

1. Open Visual Studio 2012, click on Tools from the file menu bar and then click Options,

2. From the Options window, expand the Source Control option, click on Plug-in Selection and make sure that the Current source control plug-in is set to Visual Studio Team Foundation Server.

3. Next, click on the Visual Studio Team Foundation Server option under Source Control and perform the following steps: Check Use proxy server for file downloads. Enter the host name of your preferred Team Foundation Server 2010 Proxy server. Set the port to 443. Check Use SSL encryption (https) to connect.

4. Click the OK button.

Using exe.config:

Modify the devenv.exe.config where IDE executable is like this:

Declare your proxy at proxyaddress and remember bypasslist urls and ip addresses will be excluded from proxy traffic.

Then restart visual studio to update changes.
