title: Creating unit tests for .net5 projects
body: <p>Trying to move from .Net4.5 to .Net5, so i have created my solution, which consists of folders called "Solution Items" and "src".</p>
  
  <p>I have managed to get 3 projects building using .NET 5.  I had to create the projects as "Class Library (Package) - PREVIEW - A project template for creating a class library as a NuGet package that can target any platform"</p>
  
  <p>Now i want to put my unit test projects into my solution.  I believe that i have to use XUnit now, which has different attributes for tests. </p>
  
  <p>But if i create a "Unit Test Project", i cant reference my new .net5 projects.</p>
  
  <p>Can someone point me in the right direction please.  </p>
