WAMP Protocol in Unity?

WAMP is an open standard WebSocket subprotocol that provides two application messaging patterns in one unified protocol: Remote Procedure Calls + Publish & Subscribe
http://wamp-proto.org/

Because multiplayer games use RPCs calls, this seems very useful in Unity. I've found a C# project called WampSharp:
https://github.com/Code-Sharp/WampSharp

I've imported the DLLs into Unity 2017.3.0f3 but I'm getting an error:

Code (CSharp):

1.  
2. Exception: RemoteCertificateChainErrors
3. Rethrow as AggregateException: One or more errors occurred.
4. System.Threading.Tasks.Task.ThrowIfExceptional (System.Boolean includeTaskCanceledExceptions) (at <c95265f74fdf4905bfb0d5a4b652216c>:0)

7. WAMPClientTest.Main () (at Assets/WAMPClientTest.cs:27)
8.  

I've reported the error as an Issue at GitHub:
https://github.com/Code-Sharp/WampSharp/issues/224

However, it's possible I've just made a mistake or there's a problem with experimental 4.6 API build in Unity?

If you have any insight, please help out

 

Did the WAMP tutorials work for you? http://wampsharp.net/wamp2/getting-started-with-wampv2/

 

I could not get the DLLs to work inside of Unity, even using .Net 4.6 build. Here's the exception:

I opened an issue on Gibhub and the developer indicated there seems to be an issue with System.Reactive:
https://github.com/Code-Sharp/WampSharp/issues/224
He asked me to try to reference the .NET Standard 2.0 dlls, which means I would have to wait for the 2018 Beta.

 

I meant, were you able to get WAMP working OUTSIDE of Unity first, as a test.

 

I got the same InvalidCastException in my app. My app refers to System.Reactive.Core/Linq/Interface 3.1.1 nuget packages.

The static constructor of the Observable class in System.Reactive.Core tries to load System.Reactive.PlatformServices by reflection if it exists. In Unity, the PlatformServices is found in MonoBleedingEdge/lib/mono/4.5 but its version is 2.2.0. And then, the cast is invalid because of loading the same class from other versions.
