How to use dotnet restore on Visual Studio Team Services Hosted Build Agent with VSTS Nuget feed

Question

I have a .Net Core 1.0 class library that uses a Nuget package that is hosted in a Visual Studio Team Services Nuget feed.

We use the Visual Studio Team Services to build the class library and have a build definition with a build step that does a dotnet restore on the project. The command fails with the following errors:

2016-06-28T13:07:09.0634265Z ##[warning]File name doesn't indicate a full path to a executable file.

Obviously it fails because FeedName requires that we authenticate to it, which is why we also have this nuget.config file alongside our project.json:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
    <add key="nuget.org" value="https://www.nuget.org/api/v2/" />
    <add key="FeedName" value="https://Company.pkgs.visualstudio.com/DefaultCollection/_packaging/FeedName/nuget/v2" />
  </packageSources>
  <packageRestore>
    <add key="enabled" value="True" />
    <add key="automatic" value="True" />
  </packageRestore>
  <bindingRedirects>
    <add key="skip" value="False" />
  </bindingRedirects>
  <FeedName>
    <add key="Username" value="username" />
    <add key="ClearTextPassword" value="the_actual_clear_text_password" />
  </FeedName>
</configuration>

This works if we use the Nuget Installer build step, but with dotnet restore it does not.

Please help, this is the missing part we need to continue using Visual Studio Team Services to build our projects.

You can refer to this link for details: .NET Core.

.NET Core doesn't currently support encrypted credentials. To use VSTS NuGet feeds with .NET Core applications, you'll need to specify a Personal Access Token in plain text.
