    I'm targeting the latest UWP apis but getting this re-writer error and I'm not sure how to fix it.

    @Tautvydas-Zilys is there something I'm missing here?

    Using .net 4.x and il2cpp

    Reference rewriter: Error: method `System.Numerics.Vector3[] Windows.Perception.Spatial.SpatialStageFrameOfReference::TryGetMovementBounds(Windows.Perception.Spatial.SpatialCoordinateSystem)` doesn't exist in target framework. It is referenced from XRTK.WindowsMixedReality.dll at System.Boolean XRTK.WindowsMixedReality.Providers.BoundarySystem.WindowsMixedRealityBoundaryDataProvider::TryGetBoundaryGeometry(System.Collections.Generic.List`1<UnityEngine.Vector3>&).

    Which Unity version are you on? Generally that error indicates that either you're using APIs from a newer Windows SDK that you're targeting, or there's an issue in reference rewrite not properly projecting Windows Runtime types (there have been a few known issues there but I thought we fixed them). If it's the latter, you can ignore the error: it will not cause the build to fail (but we'd like a bug report).

    I'm using 2019.1.14f but was able to reproduce it with 2019.4.1 LTS

    I double checked the API targets and that seems to be correct. I'm thinking it might be the latter?

    I'll go ahead and file the bug report

    Does it cause any issues at your app runtime?

    That method doesn't seem to return any data when it should.

    Thanks, we will take a look.

    If there's no exception at runtime, it's likely is working correctly. Are you sure that API is supposed to return stuff when you're using it the way you are? It's very unlikely data gets lost on IL2CPP side if the call is made successfully. I would suggest looking at that because our fix will likely just be fixing this error without any other functional changes.

    It's working. I made a simple mistake of not actually loading the test level /facepalm.

    The backport is in progress. Unfortunately I have no ETA at this point.

    Is this blocking you in any way? That error is purely cosmetic and should not cause issues at runtime.

    It is not, just curious about the level of effort for LTS

    Backports work on priority basis: higher priority issues are prioritized. This particular issue was deemed as cosmetic and was given low priority.
