I just upgraded to ArcGIS Pro 2.5 and the .NET project I am working on no longer 'Builds'. The is the error....
Error The tag 'ProWindow' does not exist in XML namespace 'clr-namespace:ArcGIS.Desktop.Framework.Controls;assembly=ArcGIS.Desktop.Framework'. Line 1 Position 21.
Can someone explain what I need to do to get things going again?
Thanks,
