Chances are you need to compile first before you can view.

Subject: [wix-users] Problem loading designer for current WixBA code

The e-mail below is from an external source.  Please do not open attachments or click links from an unknown or suspicious origin.

Using VS 2015 Update 2, with SDK 10 and WDK 10 installed.

I located the sample code for the wixba to try and learn how a custom ba is written and how it works.  When trying to view the RootView.xaml in the designer, it chokes with the following:

Value cannot be null.
Parameter name: targetPlatformIdentifier
   at Microsoft.VisualStudio.DesignTools.Platform.PlatformCreatorBase.IsCompatiblePlatform(PlatformIdentifier targetPlatformIdentifier, PlatformIdentifier guestPlatformIdentifier)
   at Microsoft.VisualStudio.DesignTools.WpfDesigner.WpfPlatformCreator.IsCompatiblePlatform(PlatformIdentifier targetPlatformIdentifier, PlatformIdentifier guestPlatformIdentifier)
   at Microsoft.VisualStudio.DesignTools.Platform.PlatformService.IsCompatiblePlatform(PlatformIdentifier hostPlatformIdentifier, PlatformIdentifier guestPlatformIdentifier)
   at Microsoft.VisualStudio.DesignTools.Designer.Project.ProjectContextManager.GetCompatiblePlatformIdentifier(IHostProject project)
   at Microsoft.VisualStudio.DesignTools.Designer.Project.ProjectContextManager.GetProjectContext(IHostProject project, IPlatform platform, Boolean create)
   at Microsoft.VisualStudio.DesignTools.Designer.Project.ProjectContextManager.GetSourceItemContext(IHostSourceItem sourceItem)
   at Microsoft.VisualStudio.DesignTools.Designer.DesignerService.CreateDesigner(IHostSourceItem item, IHostTextEditor editor, CancellationToken cancelToken)
   at Microsoft.VisualStudio.DesignTools.DesignerContract.Isolation.Remoting.RemoteDesignerService.<>c__DisplayClass12_0.<Microsoft.VisualStudio.DesignTools.DesignerContract.Isolation.Remoting.IRemoteDesignerService.CreateDesigner>b__0(CancellationToken cancelToken)
   at Microsoft.VisualStudio.DesignTools.DesignerContract.Isolation.Remoting.RemoteDesignerService.<>c__DisplayClass6_0`1.<MarshalInWithCancellation>b__0()
   at Microsoft.VisualStudio.DesignTools.DesignerContract.Isolation.Remoting.STAMarshaler.Call.InvokeWorker()

... and it continues on with "server stack trace", "Exception rethrown at [0]: ", etc.

I haven't played with WPF before, so I don't know what I might need to adjust to load the designer... What would I need to do in this case?
