Error running in Hololens

jornh · January 4, 2017, 8:36am

After upgrading to 5.6 beta (and build to Universal 10, Hololens) i get some errors running in Hololens. The same happens running in the HoloLens Emulator.

Exception: Incorrect hashcode or refCount - (GCHandleToObject)

Hi, Jørn.

It looks like there’s a problem with the WorldAnchorStore.GetAsync() invocation. What are you passing as a parameter?

Could you post a bug report with your project so we can take a look?

Same here, the thing is that the GetAsync method sometimes work and sometimes don’t. (I’m using the device, not the emulator).

Although the log shows an exception, i’m trying to catch it but nothing happens, and the “onComplete” delegate is also never called.

yes, I got the same on 5.6.0b8.
WorldAnchorStore.GetAsync never gets triggered.
Just after starting the Observer when you run an app on the Device (No Remote to Device), you get this:

Guys, we need a bug report with a repro project in order to fix this.
