Designer issues should be reported to Microsoft as there is nothing we can do to fix this on our side.

@Zeleksonob Make sure that you have added all necessary MahApps resources at App.xaml. What you are missing exactly?

@punker76

I'm missing buttons, Tile , properties like text, count, image, and background color.

, maybe I'll do missing a resource, could you look at the images below, please?

App.xaml

this is what my designer looks like :

@punker76 any suggestions?

Hi @Zeleksonob ,

make sure the project is build correctly and that custom controls are activated in the designer.

Even then like @batzen already said the designer for WPF is buggy, but we cannot solve it. I personally write my UI completly in XAML

Happy coding Tim
