    We will use Microsoft.NET.Sdk.WindowsDesktop targets directly when local PresentationBuildTasks is not available
    We do not need to import Microsoft.NET.Sdk.WindowsDesktop.props from the Sdk - this only provides us with
    WPF references and Page, ApplicationDefinition globbing functionality - neither of which is used by our projects.

    If we had needed to use this props file, we'd have imported it like this:

    <PropertyGroup Condition="!Exists('$(LocalMicrosoftWinFXTargets)') And '$(InternalMarkupCompilation)'=='true'">
      <UseWpf>true</UseWpf>
    </PropertyGroup>
    <Import Sdk="Microsoft.NET.Sdk.WindowsDesktop"
            Project="../targets/Microsoft.NET.Sdk.WindowsDesktop.props"
            Condition="!Exists('$(LocalMicrosoftWinFXTargets)') And '$(InternalMarkupCompilation)'=='true'"/>

    The use of Microsoft.NET.Sdk.WindowsDesktop doesn't break the source-build promise.
      - Microsoft.NET.Sdk.WindowsDesktop is built from sources
      - It is used for compilation of assemblies in dotnet-wpf-int (the internal WPF repo), and serves as a
        'transport package' for PresentationBuildTasks.dll and related props+targets file.
      - When the corresponding projects move from dotnet-wpf-int to dotnet/wpf in the future, their build will
        fall back to use local PBT project outputs for their compilation (instead of using WindowsDesktop Sdk package
        as a convenient 'transport package').
