I have a c# codebehind to a web app I'm trying to add "using Microsoft.Ink" to, but it is not a valid namespace. Is there something I need to install before I do this? The documentation from Microsoft seems all over the place and there are no instructions on how to include this in the file. I checked in the modify menu for Visual Studio to see if I could add anything for tablet support and there is nothing.
How do I add "using Microsoft.Ink"?
