Error when compiling solution

I download the solution (git clone https://github.com/reactjs/React.NET.git) and run dev-build.bat and receive the following errors:

RestorePackages:

Unable to find version '2.6.3' of package 'NUnit.Runners'.

If I remove the package from .nuget\packages.config, I receive the following errors

That's bizarre... All those packages definitely exist! Do you have custom NuGet sources configured? What happens if you try to install one of those packages in a brand new project in Visual Studio?

works fine in a blank project...

I don't have any custom NuGet sources. It's a fresh install of Windows 10 and VS 2015

Really strange that it works on a blank project... to me this sounds like a NuGet issue rather than a ReactJS.NET issue 😕

Looks like the older version of NuGet I had bundled in tools\NuGet\NuGet.exe no longer works properly. I've upgraded it to a newer version and it should be fine now. I can probably just totally delete it and rely on the user to have a locally-installed version of NuGet.exe, but this will do for now.
