thanks for your reply
May be I haven’t used much wpf and it was not very straight forward for me to change the user control inheritance
from : public partial class PopUpMessage : UserControl
To : public partial class PopUpMessage : Window to get the window properties.
In wpf solution we have option for adding new wpf page, page has the method to show().
But RhinoCommon plugin project doesn’t have that, it has only the wpf user control. need to update the inheriting class as above .
Rhinocommon plugin solution
wpf solution
thanks,
