[Question] Using acrylic background in Xaml Island control causes exceptions.

Describe the bug

Hi,

I've followed this excellent guide in order to create a custom UWP control in a WPF Net Core 3.1 application. It works perfectly fine in the original state.

However when I modify the window changing the background from a solid color to "Acrylic" the application runs but throughs a few exceptions as seen below then automatically terminates itself before the window is drawn on screen. Do you know what could be the cause of this?

Thanks @spacelime, can you provide more details on what OS you're on, what VS version you're running, which NuGet package versions you're using?

Thank you, I've updated the post now.

[ocalvo]

Can you please update to the latest version 6.1.1?

Does it still repro?

[ghost]

Hi,

I havn't tested 6.1.1. The problem got solved when I implemented XAML island code directly into the WPF app, skipping the custom UWP control step of the tutorial.

Thank you, Olof

Closing it given it's no longer an issue for the developer who could workaround it.
