Deprecate Switch.System.Windows.Forms.DoNotSupportSelectAllShortcutInMultilineTextBox quirk
Version introduced
3.0
Old behavior
Prior to .NET Framework 4.6.1 the Ctrl + A shortcut key in a TextBox failed to select all text when the ShortcutsEnabled and Multiline properties were both set to true. In .NET Framework 4.6.1 the behavior has been corrected.
Switch.System.Windows.Forms.DoNotSupportSelectAllShortcutInMultilineTextBox was introduced in .NET Framework 4.6.1 to retain the original behavior.
For more information, see https://docs.microsoft.com/en-us/dotnet/api/system.windows.forms.textbox.processcmdkey?view=netframework-4.8.
New behavior
The switch is deprecated, and no alternative functionality is available.
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.
