We're making use of the MRTK package, but don't wish to include the samples in our project. We deleted the samples folder only to find that it breaks when built to the device. It turns out that the default input profile is referencing a hand tracking profile from the samples folder instead a profile from the non-samples folder.
A hand tracking profile should be added to the Providers/Profiles folder and that should be referenced by the default input profile instead so the samples folder can safely be deleted.
