New in .NET Framework 4.8.1
ARM64 Native Support
Now you no longer need to run x64 code emulators on ARM64 devices. With .NET Framework 4.8.1, native support for ARM64 devices has been added so that the .NET Framework apps and libraries can now leverage running the workloads directly.
WCAG2.1 Compliant Accessible Tooltips
Both of the new Windows UI development platforms offered by the.NET Framework 4.8.1 give programmers the assistance they need to develop programs that are accessible to users. The handling of tooltips has been improved in Windows Forms and WPF to make them more accessible. Tooltips now adhere to the standards outlined in the WCAG2.1 content on Hover or Focus recommendation in both situations.
The requirements for tooltips are the following:
- Tooltips must display either via mouse hover or by keyboard navigation to the control.
- Tooltips should be dismissible. That is, a simple keyboard command like the ESC key should dismiss the tooltip.
- Tooltips should be hoverable. Users should be able to place their mouse cursor over the tooltip. This enables scenarios like using magnifiers to be able to read the tooltip for low-vision users.
- Tooltips should be persistent. Tooltips should not automatically disappear after a certain time has elapsed. Rather, the tooltips should be dismissed by the user moving their mouse to another control, or by dismissing the tooltip as described above.
Accessibility Improvements to Windows Forms
Several improvements have been to Windows Forms so that they are more user-friendly and everyone can use them. Here are the issues addressed:
- Text Pattern Support– WinForms added support for the UIA Text Pattern. This pattern enables assistive technology to traverse the content of a TextBox or similar text-based control letter by letter. It enables text to be selected within the control and changed, as well as new text inserted at the cursor. WinForms added this support for TextBox, DataGridView cells, ComboBox controls, and more.
- Contrast issues– High contrast issues have been addressed in several controls and have changed the contrast ratio of selection rectangles to be darker and more visible.
- Fixed several DataGridView issues– The scrollbar names have been updated to be more consistent. An issue where Narrator was unable to focus on empty DataGridView cells has been addressed. Developers are now able to set the localized control type property for Custom DataGridView cells. The link color for DataGridViewLink cells has been updated to have better contrast with the background.
