How can I develop an app that acts as a touch keyboard?
Thanks.
Depends on edition, a keyboard text service is a desktop app, so you can't get it installed on Windows RT.
I think you need to implement the soft keyboard interface on the same object that exposes ITfTextInputProcessor.
I think you need to implement ISoftKbd

Does Windows8 support ISoftKbd interface? Is it compatible with MetroUI? Is there any sample to use it?
Thanks
