title: Where is the package sources location
body: <p>I use VS 2015 .Where in the visual studio project store the setting of  Tools>options >Nuget Package Manager >Package Sources's setting. Currently Nuget.org is checked for Package Sources.I want to point this to a different location other than <a href="https://www.nuget.org/api/v2/" rel="nofollow noreferrer">https://www.nuget.org/api/v2/</a>, by editing the file location.
  I checked the project file csproj, but did not find it
  I need to change this manually in the server to point to the server repository. Working fine in local machine but not in the server.</p>
