DLLs raise issue when building for Hololens/UWP

[ghost]

Hi,

When building for windows store, unity says that included Newtonsoft.json DLL is incompatible with Windows Universal App platform.

UnityException: Failed to run reference rewriter with command --target="Temp\StagingArea\Newtonsoft.Json.dll" --additionalreferences="Temp\StagingArea","C:\Program Files (x86)\Windows

Error: type `System.Runtime.Serialization.SerializationInfo` doesn't exist in target framework. It is referenced from Newtonsoft.Json.dll at System.Void Newtonsoft.Json.JsonException::.ctor(System.Runtime.Serialization.SerializationInfo,System.Runtime.Serialization.Streaming<message truncated>

These go away after replacing the DLL with a portable one from https://github.com/JamesNK/Newtonsoft.Json/releases.

After that, it works fine, but then another DLLs have similar issues that are not so easily handled (logs below). Most of the errors relate to namespaces like System.Security, System.Threading and others that have different analogues in the UWP world.

Facing the same issue.. Any solutions ?

I don't think this can be fixed easily. Socket.io alternatives like SignalR also don't work. I got around it by polling with a REST API.

The one thing I didn't try is websockets. This library https://github.com/SoylentGraham/Websocket-Sharp-UWP claims to work, so maybe you can check it out.
