Xaml Rules compilation stops working when adding WPF Xaml pages

[josesimoes]

I'm trying to reach the TargetPath property for a project on the DeployProvider.

1. can't use Properties.GetConfigurationGeneralPropertiesAsync() because the build fails.
   Actually there are no errors listed, I can only see this on the build output window. The partial class is there and exists on the obj folder.

2. Trying to use the dereferenced property fails because types are missing:
   (new System.Threading.Tasks.SystemThreadingTasks_FutureDebugView<Microsoft.Build.Evaluation.Project>(((Microsoft.VisualStudio.ProjectSystem.ConfiguredProjectImpl)Properties.ConfiguredProject).MSBuildProject).Result).AllEvaluatedProperties["TargetPath"]

Do you have by any chances any WPF xaml files in the same project?

[josesimoes]

Yes I do. There is a ToolWindow that hosts a WPF page.

This issue is now fixed in Microsoft.VisualStudio.ProjectSystem.SDK.Tools 15.3.224

In order to apply the fix, you will need to upgrade the nuget package used by your project to that version.

I am still able to reproduce the problem with VS SDK 15.8.243.

It seems that https://github.com/microsoft/PTVS/blob/master/Build/CommonProjectSystemExtension.targets is not imported in the generated csproj while one uses PackageReference.

I can workaround the problem by manually importing the targets in my csproj like

  <Import Project="path\to\global\packages\microsoft.visualstudio.projectsystem.sdk.tools\15.8.243\build\Microsoft.VisualStudio.ProjectSystem.Sdk.Tools.targets" Condition="!$(PrepareResourceNamesDependsOn.Contains('GenerateRuleSourceFromXaml'))"/>
