Have the latest releases to Windows IoT included an On Screen Keyboard? I am aware of other suggestions that use the webview to provide a keyboard, but I would prefer an OSK for my UWP app. Ideally internationalised.
On Screen Keyboard is not mentioned in the latest release 14931, so the answer is no at the moment.
Part of the reason for this is that we don’t have a ‘shell’ like explorer that is there helping control what app is running or providing other services such as SIP / OSK as is handled on the desktop.
Longer term I believe this is something that the product team is considering / looking into but I do not have any timeline on if or when it might be an option (if ever).
The following link is the MSDN post you can reference:
Update:
It is available. Please refer to "Windows IoT Core - On-screen keyboard for headed devices".
