title: Dotnet Installing Custom Templates Issue
body: <p>I have created a project Template for MS Orleans Grain (.NET Standard 2.0 project)
  To install using this command:</p>
  
  <pre><code>dotnet new -i OrleansGrain.NetCore.ProjectTemplate::*
  </code></pre>
  
  <p>The package is hosted on Nuget.org, with .NET Console App I managed to make it work, but this package is .NET Standard 2.0 Class Library and when I try to install i got the following error message:</p>
