title: Xunit Namespace Could not be Found in Visual Studio Code
body: <p>I'm using Visual Studio Code for a .NET Core Project.
  I have an ASP.NET Core Project for which i want to create a separate unit tests project, i created a sub folder and ran</p>
  
  <pre><code>dotnet new xunit
  dotnet restore
  </code></pre>
  
  <p>When i tried to run it from the cli "dotnet build" "dotnet run" it ran successfully, however in visual studio, it says that it can't find the namespace Xunit</p>

  <p>This is very strange because Visual Studio code has worked fine for me so far, it never had problem with dependencies, it only has this problem with Xunit.</p>
  
  <p>Anyone familiar with this issue?  </p>
