Mixedreality-webrtc: Build error

[jahnotto]

Hi,

I am getting a build error after pulling the lastest master (59df5a141edf80639b08e40480b7a2bca85595d8 [59df5a1]).

I am using Visual Studio 2019. I am not upgrading to a newer toolset or windows sdk when I'm loading the solution.

Any ideas?

Same issue here, seems the DLLs are still generated in C:\mr-webrtc\bin though, so you could check that folder and see if they are there.

They are there! Thanks.

I have experienced the same yesterday. This seems to be a regression, but I don't know yet if it's related to changes in the packages or to the latest Visual Studio update which brings support for the newly released .NET Core 3.0, because I had quite a lot of troubles with that and NuGet.

Actually I can confirm that on Visual Studio 16.1.2 all projects of the solution build correctly on 59df5a1 (latest master).

[eirikhollis]

Makes sense, I'm running 16.3.2 right now

And I can confirm on 16.3.2 it doesn't work anymore. This is an expected regression, because I was hoping to release a v1.0 at the end of the week, so that's why all regression bugs are popping up this week 😒

By the way you can temporarily work around the issue by commenting all but one Microsoft.MixedReality.WebRTC.Native.Core.WinRT.* package in the packages.json so that there's no conflict anymore. Pick the one you use most (_e.g._ x64 Debug).

Thanks for following up so quickly @djee-ms

Auto-closed by mistake, but should be fixed now with new packaged (0.2.2-preview-20191008.1) as of 8141ded471a169e0267c66f3d366a1d369bf6907.
