* [Core] Added a builder for application messages using a fluent API
* [Client] Added a first version of a managed client which will manage the connection, subscription etc. automatically (Thanks to @JTrotta)
* [Server] Added support for WebSockets via ASP.NET Core 2.0 (Thanks to @ChristianRiedl)
* [Client] The session state response from the server is now returned in the _ConnectAsync_ method and also part of the _Connected_ event args
