I have tried to convert an application with .net 6.0 to .net framework 4.8 but the wpf.ui didn’t show errors but still can’t work. Even a simple frontend code like button can’t use, if applied the ui tag like <ui:UiWindow> or <ui:Button>. So, Im wondering whether the wpf-ui able to use in .net framework 4.8 framework and how to use it correctly.
