Likewise the other samples relying upon spatial mapping aren't working either.
Upon saying 'show results' the resulting map appears to be multiple replicas of the same room added into the one space.
So standing in one room, having deleted all existing spaces, then remapping just the one, and starting the program shows the single room replicated at least 5 or 6 times.
Took these actions:
1. Updated UWP to latest
2. Updated SharpReality to latest
No change, still faulty.
Haven't run these samples in over a year, but last time I ran them all worked fine.
All versions set to latest.
