Hello
Before I had VS 2019 and all of my application worked very well with (.net 4.8) ,But today I installed VS 2022 and when I open each application in the Blend Visual studio it gives this error:
The member "VisualStateGroups" is not recognized or is not accessible.
But if I open it in VS 2019 again everything is ok.
Do I need to install something?
Thank you.

do you have any solution?
Many of my styles doesn't works - therefore I had to go back to VS2019.Regards
