Thank you for writing.
The DPI scaling mechanism works differently in Windows Forms. It basically calculates a scaling factor depending on the system settings on which the form has been designed and the system on which the application is run.
The application also needs to be declared as DPI-aware. We have a nice blog post discussing in details this topic: WinForms Scaling at Large DPI Settings–Is It Even Possible?
I hope this helps. Should you have further questions please do not hesitate to write back.
