Visual Studio 2022 can't add controls to toolbox

[charesch]

I am using VS 2022 to create a simple .net 6.0 application. I need the maskedtextbox but i can't add the controls to my toolbox.

I installed the package via nuget package manager. In the toolbox, I've tried adding a tab, then chose items and add the DotNetProjects.Wpf.Extended.Toolkit.dll but it throws this error :

"*.dll targets a platform whose toolbox items cannot be enumerated dynamically"

What am i doing wrong?
Thank you very much for your time

Think it's an issue with the designer:

MahApps/MahApps.Metro#3734

You can use the items, but not via the toolbox

i've now also created a net6 version, maybe this helps

You're right, it works when you add the controls directly in xaml. It displays at design time and does its job at run time.
I would like to see the list in my toolbox, but it is a minor issue. I've got what i wanted.

Thank you for your help!
