[WinForms] Deprecate Switch.System.Windows.Forms.DoNotLoadLatestRichEditControl quirk #14173
Description
Deprecate Switch.System.Windows.Forms.DoNotLoadLatestRichEditControl quirk
See Switch.System.Windows.Forms.DoNotLoadLatestRichEditControl compatibility switch not supported for updated documentation for this change.
Deprecate Switch.System.Windows.Forms.DoNotLoadLatestRichEditControl quirk
Version introduced
3.0 Preview9
Old behavior
In the .NET Framework 4.6.2 and previous versions the RichTextBox control would instantiate the Win32 RichEdit control v3.0 (versions differences), and for applications retargeting to .NET 4.7.1, the RichTextBox control would instantiate RichEdit v4.1 (msftedit.dll).
Switch.System.Windows.Forms.DoNotLoadLatestRichEditControl was introduced to allow applications targeting .NET 4.7.1 and later to opt-out of the new RichEdit v4.1 and use the old RichEdit v3 instead.
New behavior
The switch is deprecated, only new versions of RichEdit control are supported.
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.
Ensure the code dependent on the switch contiues to work correctly.
