Nuget and Proxies

If you need to access the from behind a corporate firewall that needs authentication, one might think you need a custom nuget.config file with your proxy server URL and user/password settings.

It appears that even up to nuget 4.1, this is still not the case, the proxy settings need to reside in the default nuget.config location which is at %APPDATA%\NuGet\NuGet.Config.

This is covered in details in this nuget bug.

So, if you want to get out through the proxy easily, configure your nuget with the following:

nuget.exe config -set http_proxy=""
nuget.exe config -set http_proxy.user=Username
nuget.exe config -set http_proxy.Password=Password

Do not store these in a separate config file! Make sure they go to the default!

In other words, don't do this:

nuget.exe config -set http_proxy="" -ConfigFile=D:\nuget\nuget.config

Then when you run your nuget restore, it should work
