title: Unable to generate a Nuget Package in VSTS Build
body: <p>I have a dotnet core library that I'm trying to publish to my VSTS hosted Nuget feed. I have a problem in that it doesn't seem to be doing anything. The build is completing without errors but the nupkg file seems to be neither created nor pushed. The build log below contains an error as I am trying to publish the output as a build asset but there is no output to publish...</p>
  
  <p>(log start cut off for brevity)</p>
