title: error CS0246: The type or namespace name could not be found (are you missing a using directive or an assembly reference?)
body: <p>I am new to the .NET Core and xUnit. I would like to run xUnit tests from command line (CI pipeline). The project contains referenced dll (via <code>&lt;PackageReference Include=&quot;some_library.dll&quot;&gt;</code> in the csproj file). When running <code>dotnet test</code> from command line I get the following error:</p>
  <pre><code> error CS0246: The type or namespace name could not be found (are you missing a using directive or an assembly reference?)
  </code></pre>
  <p>Running tests from within VS is without any problem.</p>
  <p>How shall I run tests in such a way that the referenced library will be included also when running tests from cmd?</p>
