As part of migration from 2.5.2 version to 5.0.0.4 version of Go Diagrams (WinForms) I found this exception.
Can you please help me to resolve this?
System.MethodAccessException: Attempt by security transparent method ‘Northwoods.Go.GoText+ComboBoxControl.OnHandleCreated(System.EventArgs)’ to call native code through method ‘Northwoods.Go.GoText+ComboBoxControl.SetWindowTheme(IntPtr, System.String, System.String)’ failed. Methods must be security critical or security safe-critical to call native code.
