Hi,
I need to insert a UserControl onto a TabPage on a main form but it does not work for me.
I have .NET5 WPF project in MS VS 2019 v 16.9.4.
Can someone help me ? Here is my source code:

The command <app:ProcessView /> does not work and shows me this error:
Severity Code Description Project File Line Suppression State
Error XDG0008 The name "UserControl1" does not exist in the namespace "clr-namespace:WpfApp". WpfApp c:\1\WpfApp4 TabControl\WpfApp\WpfApp\MainWindow.xaml 12
thanks Jerry
