When I'm trying to add System.Windows.MessageBoxOptions.ServiceNotification, am getting error message.
here is the code.
MessageBox.Show("Correct", "Warning", System.Windows.MessageBoxButtons.OK,System.Windows.MessageBoxImage.Warning,System.Windows.MessageBoxOptions.ServiceNotification)
When I use, System.Windows.MessageBox.Show(........) am getting the message box in-front of all the windows. But the UI of the Messagebox is like normal windows form, not the ArcGIS Pro UI.
