A simple signalR Hub Protocol using protobuf to compress and send your data using binary.

Usage

Call AddProtobufProtocol extension method in your ConfigureService with types of protobuf message you will serialize. Types are needed in order to be able to deserialize the message. Note that client and server must supply the same types to deserialize property.

public void ConfigureServices(IServiceCollection services)
        {
            // Some services
            services.AddSignalR().AddProtobufProtocol(new[] { typeof(ProtobufObject1), ...,  typeof(ProtobufObjectN)});
            // Some other services
        }
