[WinForms] Deprecate Switch.System.Windows.Forms.DomainUpDown.UseLegacyScrolling quirk #14160
Description
Deprecate Switch.System.Windows.Forms.DomainUpDown.UseLegacyScrolling quirk
See Switch.System.Windows.Forms.DomainUpDown.UseLegacyScrolling compatibility switch not supported for updated documentation for this change.
Deprecate Switch.System.Windows.Forms.DomainUpDown.UseLegacyScrolling quirk
Version introduced
3.0 Preview9
Old behavior
In the .NET Framework 4.7.1 and previous versions the DomainUpDown control's UpButton action is ignored when control text is present, and the developer was required to use DownButton action on the control before using UpButton action. Starting with the .NET Framework 4.7.2 both the UpButton and DownButton actions work independently in this scenario and remain in sync.
Switch.System.Windows.Forms.DomainUpDown.UseLegacyScrolling was introduced in .NET Framework 4.7.2 to allow to opt-out of the fixed behavior and retain the original behavior.

New behavior
The switch is deprecated, and no alternative functionality is available.
UpButton and DownButton actions work independently in this scenario and remain in sync.
Reason for change
.NET Core 3.0 is a new moderm development platform, and it brings significantly simpler servicing scenarios, thus allowing for removal of quirks targeting specific legacy use cases.
Recommended action
Remove the switch.
