I am currently trying to update Vuforia in Unity from a very old version (not quite sure which one exactly, but it's many years old at this point).
With the new version of Vuforia, i'm now missing assembly references for MarkerTracker & MarkerAbstractBehaviour. Even though i can see the VuforiaUnityExtensions.dll file in the package, and I've got the using Vuforia namespace present.
I've tried everything at this point, and there's no documentation anywhere about this issue.
Can anyone please help?
