Base bproject create Failed to create Nuget core cache

Question

I am trying to launch my first .Net Core solution.

When I try to create a project in VS 2015, it fails. So, back to the basics.

Using these guidelines: MS.Net Core

I have done it.

C:\dev\Tests>mkdir hwapp2
C:\dev\Tests>cd hwapp2
C:\dev\Tests\hwapp2>dotnet -v new

I run this on the command line as an administrator. The same thing happens when I try to create a project in VS 2015. I tried it with Firewall disabled, by the way.
