Hi,
Xaml designer can't displayed content in the runtime design mode
but, complie and excute all OK
The VS2019 project was made with WPF R3 2020, updated to WPF R1 2022 with VS2022 and compiled.
when installing wpf r1 2022, the installation folder was designated separately, and framework 4.6.2 was used.
Also, i tried to create a new one using the telerik template tool in vs2022 and tried it with
telerik ui for wpf->confiure project or upgrade wizard in 2019 existing project, but it didn't work.
