Publishing WebRTC app on Microsoft Store failing WACK

[anders-lundgren]

So I've managed to work around the issues described in #59, and am now trying to publish the app to Microsoft Store. Unfortunately the build failed WACK prior to publishing, with the following error message:

Error Found: The general metadata correctness test detected the following errors:
Parameter __returnValue of method CreateMediaStreamSource of type Org.WebRtc.__IMediaPublicNonVirtuals in file Org.WebRtc.winmd references the non-Windows Runtime type IntPtr. Windows Runtime types can reference only Windows Runtime types.
Parameter __returnValue of method CreateMediaStreamSource of type Org.WebRtc.Media in file Org.WebRtc.winmd references the non-Windows Runtime type IntPtr. Windows Runtime types can reference only Windows Runtime types.
Impact if not fixed: Microsoft store doesn't allow apps that don't pass Windows Runtime Metadata Validation. 
How to fix: Please ensure that the compiler you are using to generate your Windows Runtime types is up to date with with the Windows Runtime specifications. 

Is there an easy way to fix this that I'm overlooking?

Are you using the nuget package, and if so, which version?

I'm using the Unity example by recursively cloning the m71 branch of https://github.com/webrtc-uwp/webrtc-uwp-sdk, which includes this repository, and build everything from scratch, don't think there's a good way to import nuget packages to Unity unfortunately.
