Answer 1

In the RTM of Team Foundation Server 2015 you have to add a build step of the type "NuGet Installer", and restore the packages of the Solution file before you run the actual build process. In this task you can pass the argument -ConfigFile path/to/nuget.config which contains your repository path.

For Example:

<configuration>
  <packageSources>
    <add key="Internal Nuget" value="\\srv-nuget\Repo" />
  </packageSources>
</configuration>

Alternatively you could also add a NuGet Installer build step before the Visual Studio Build step in your build configuration to restore all NuGet packages.

There you can pass the location of your private repo as argument to nuget.exe:

-source "https://www.nuget.org/api/v2/;http://mynugetserver"
