Removal of the Design DLL makes Drag&Drop from Blend 2022 break

[sonnemaf]

Hi,

In the 3.0 release the Design DLL is removed. This breaks the Drag&Drop of a behavior/action in Blend 2022.

Just create a Blank UWP app and Install the NuGet Package.

Drag&Drop an Action to a Control.

After dropping a ChangePropertyAction on a button I get this exception.

If I downgrade to version 2.0.1 it still works fine.

Adding Behaviors in XAML isn't very hard but using Blend for newcomers (which I Train) was always handy. I hope this can be fixed.

Thanks,

Fons
