Answer 2

This is a rather old question, but I want to share my solution/opinion. I ran into a similar problem recently. Actually, I want Visual Studio to keep my WinForms as they are, but them to scale at runtime. I found no consistent summary on how to correctly do that. After some reading and experimenting I came to this solution:

• Keep the Form’s AutoScaleMode = Font.
• Set in your Forms Designer: Font = MS Sans; 11px
• In the Forms Ctor, after InitializeComponent, set: Font = SystemFonts.DefaultFont
• Enable DPI-Awareness, either through a manifest or by API function SetProcessDPIAwareness

Since AutoScaleMode remains active, all DPI-changing magic works, even per-monitor DPI awareness. What remains, is designing Forms in a way scaling works nicely.
