the web page on your web site "ATK, CDK, SDK – What does it mean?" seems need an update to include II SDK.
Please note I am on Windows 10.
The whole web site seems confusing about those technologies. ATK is mentioned in some web page here but I can't find the link to download ATK and its examples.
After going through your web site, my understanding is that ATK and CDK are replaced by II SDK. But I don't know what is the relationship between MyScript SDK and II SDK.
For developing UWP application, it seems we have to include MyScript.InteractiveInk.UIReferenceImplementation.Uwp? I downloaded from github ii sdk example. I didn't find much explanation about how to use UIReferenceImplementation. Hopeful you can add to the online documents.
