I've looked everywhere but I can't find any solution. If anyone could help, it would be very much appreciated since I'd like to get this build ready by tomorrow.

 

The error is shown (a little hard to read since the stack trace is pretty long):

Do you have this DLL in your project? it seems to fail in finding it..

 

I do have that DLL in my project, although the Windows 10 platform wasn't included in it's import settings. Thanks a lot!

 

Is it intended to work with Windows 10? if so you should check that DLL for the Windows 10 platform...

 

I had to download a different version of the DLL that does work with Windows 10. Building goes fine now. I am running into a whole lot of other issues when running the game on Windows Phone, but that's a whole different story.

 

Where did you get the DLL for the Windows 10 platform? Is it this one:
Json110r1\Bin\portable-net45+win8+wpa81+wp8

 

The OP's throw away account name should have told you all you need to know, but regardless he hasn't logged in since 2016.

 

I am working with an example from Microsoft which deals with running WebRtc on Universal Windows Platform, more specifically the Peer-CC example (https://github.com/Microsoft/WebRTC-universal-samples/tree/master/Samples/PeerCC-Sample)

For me, the project was missing some

.dll

(more specifically

Org.webRtc.dll

). I copied the

.dll

but not the associated

.winmd

file.

That was causing this error and was solved after coping the

.winmd

file.

 

I have the same issue, i have downloaded what you linked, but there is no Org.webRtc.dll there. Where can i download it and where should i put it

 

I have the same issue, but nothing seemed to work for me. I try to build for hololens 2. Does anyone have some ideas?
