  • .NET Core Version: 3.0 Preview1 (3.0.100-preview-009812)
  • Windows version: win10 1809 17763
  • Does the bug reproduce also in WPF for .NET Framework 4.8?: No

Problem description:
This is probably a know issue of the first preview, very excited about this thing by the way!

Running my app, I get exceptions for windows that contain a System.Windows.VisualStateGroup(only tested via xaml). See below.
I had this on three different windows and removing the VisualStateGroup fixes it. (That of course also removes the functionality)

I guess this is not yet done? Known Bug? Or something real?

Actual behavior:
System.Windows.Markup.XamlParseException: "'Set connectionId threw an exception.' Line number '11' and line position '14'."
Inner Exception:
InvalidCastException: Unable to cast object of type 'System.Windows.VisualStateGroup' to type 'System.Windows.Shapes.Ellipse'.

Expected behavior:
Should work as it does in dotnet framework.

Minimal(ish) repro:

<Grid Name="TheEllipse" MouseUp="TheEllipse_MouseUp">
        <VisualStateGroup Name="MouseStates">
            <VisualState Name="MouseEnter">
                    <ColorAnimation To="#A1A1A1" Duration="00:00:00.3" Storyboard.TargetName="BackFill" Storyboard.TargetProperty="(SolidColorBrush.Color)" />
   <Ellipse Stroke="Black" StrokeThickness="1">
           <SolidColorBrush x:Name="BackFill" Color="#F1F1F1" />
