Converting an old unit test project leaves reference to MS Test Framework

[mungojam]

I'll try and post an example project later, but after converting two old unit test projects, I was left with the following references in each one which I had to manually delete:

  <ItemGroup>
    <Reference Include="Microsoft.VisualStudio.QualityTools.UnitTestFramework, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a, processorArchitecture=MSIL" />
  </ItemGroup>

    <Reference Include="Microsoft.VisualStudio.QualityTools.UnitTestFramework">
      <HintPath>..\..\..\..\..\..\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\PublicAssemblies\Microsoft.VisualStudio.QualityTools.UnitTestFramework.dll</HintPath>
    </Reference>

The MSTest unit test packages had been correctly added in so it clearly detected that they were unit test projects.

I also have this and the converted CodedUITest can't be compiled, because the CodedUITestAttribute is not found

I've created a new CodedUI Project in VS2017 15.6 and here the old format is used. So is CodedUI not compatible with the new csproj format? Should it be excluded?
