HelixToolkit.Core.Wpf 2.21.0 -"Teapot" not found assembly in WPF .NET 6.0

[MauNguyenVan]

Hi.
I'm a new member of the learning helix toolkit.
Now I'm getting issues to add "teapot" to viewport3D - "Could not load file or assembly 'HelixToolkit.Wpf, Culture=neutral, PublicKeyToken=null'. The system cannot find the file specified.".
What's wrong with the teapot or where am I wrong.
Thank you.

I don't think there is a Teapot visual in helixtoolkit wpf. Not sure where you get this example from.

@holance I think it's a bug, not a question label.

I found the code occurred exception in .NET core ( image below). but in .NET Framework run OK.

Sorry, I found but I can not fix it.

I hope someone can fix it
