Demonstrates inability to push .net core 3.1 project that references Microsoft's Slow-Cheetah (3.2.18 as of the time of this writing) transform package for Visual Studio.

To reproduce:

• Download the repo and set for Release build in the Configuration selector.
• Build and run the app to confirm all dependencies are set.
• Right-click the ClickOnceCoreSlowCheetah project and hit "Publish..." to invoke ClickOnce.

This will fail to publish with an error about the build targets.

To fix:

• Double-click on ClickOnceCoreSlowCheetah to edit the xml and delete/comment out :

    <PackageReference Include="Microsoft.VisualStudio.SlowCheetah" Version="3.2.26">
      <PrivateAssets>all</PrivateAssets>
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
    </PackageReference>
  </ItemGroup>

• Clean the solution.
• Right-click the ClickOnceCoreSlowCheetah project and hit "Publish..." again.

This time it should succeed.

Everything in the project are defaults. I simply created a new WPF (.NET Core 3.1) App which automatically created the window. I did add a single TextBlock to it. I then used the Publish Wizard, selected Folder for Target and ClickOnce for Specific Target, and used all defaults in subsequent screens.
