Own TemplatedControl does not show in VisualBrush

[JaegerChris]

Demo.ResultViewer.zip

We have tried to use our own TemplatedControl in a VisualBrush. However, the control is not displayed in the VisualBrush.

In the example (MainWindow.axaml) we try to use our DemoPatternLocal control with a Visual Brush. It is displayed on its own, but not in the brush.

It doesn't matter if we use namespaces directly or have them mapped to an URL. It also does not matter if the control is from another assembly (DemoPattern vs. DemoPatternLocal).

Any Ideas what we are doing wrong?

Does the control show if used outside the VisualBrush? If not, could be a missing StyleInclude

Outside of the VisualBrush, the control works just fine. It only stops working as soon as we put it into the VisualBrush.
