[Problem/Bug]: WPF app that also uses Microsoft.Windows.SDK.BuildTools not possible

[clovett]

What happened?

When I add the Microsoft.Windows.SDK.BuildTools to your ~\WebView2Samples\GettingStartedGuides\WPF_GettingStarted\WPFSample.csproj

  <PackageReference Include="Microsoft.Web.WebView2" />
  <PackageReference Include="Microsoft.Windows.SDK.BuildTools" />
  <PackageReference Include="Microsoft.WindowsAppSDK" />

So that I can use Microsoft.Windows.ApplicationModel.DynamicDependency.Bootstrap.TryInitialize(0x00010005, out int hresult)

The build fails.

The tag 'WebView2' does not exist in XML namespace 'clr-namespace:Microsoft.Web.WebView2.Wpf;assembly=Microsoft.Web.WebView2.Wpf'. Line 22 Position 10.

Can you recommend a fix or workaround?
