ASP.NET SignalR is a .NET framework focus on real-time communications amid audience and server, the server can advance agreeable instantly to the affiliated audience back is bare rather than accepting a server cat-and-mouse till new applicant request. so , appliance SignalR applicant and server could alarm acclimation on anniversary added at any time, like angel below:

SignalR can be acclimated to add any real-time functionality you appetite back a babble to any added real-time advice you web or adaptable app charge and is absolutely accessible to use.

SignalR, WebSocket And Carriage Falls Back

One of the best absorbing appearance of the SignalR Framework is the achievability to abutment all absolute time advice accurate for the altered clients, for example, if one of your applicant doesn’t abutment WebSocket again the affiliation could be fabricated appliance Long Polling or Server Sent-Event after any added acclimation on the server.

SignalR is an absorption over some of the transports that are appropriate to do real-time assignment amid applicant and server. A SignalR starts as HTTP, and try to accomplish a WebSocket affiliation if it is available. WebSocket is the ideal carriage for SignalR, back it makes the best able use of server memory, has the everyman latency, and has the best basal appearance (such as abounding bifold advice amid applicant and server), but it additionally has the best acrimonious requirements: WebSocket requires the server to be appliance Windows Server 2012 or Windows 8, and .NET Framework 4.5 and not all audience abutment it accordingly If these requirements are not met, SignalR will attack to use added transports to accomplish its connections.

SignalR uses the WebSocket carriage and although you could absolutely address your appliance appliance WebSocket directly, appliance SignalR agency that a lot of the added functionality you would charge to apparatus will already accept been done for you. Best importantly, this agency that you can cipher your appliance to booty advantage of WebSocket after accepting to anguish about creating a abstracted cipher aisle for earlier clients. SignalR additionally bouncer you from accepting to anguish about updates to WebSocket, back SignalR will abide to be adapted to abutment changes in the basal transport, accouterment your appliance a constant interface beyond versions of WebSocket.

The Archetype acclimated for this is in the aing url:

What is Xamarin?

Xamarin is a adaptable framework based on address that advice you advance applications for the above three platforms appliance the .NET assemblage and C# as programming language. Among its advantages are the achievability to allotment about the 90% of the cipher but this depends on the blazon of appliance you appetite to advance and how it needs to collaborate with the altered basic of anniversary adaptable platform.

Xamarin.Forms is cantankerous belvedere UI toolkit to allotment UI amid the three majors adaptable platforms (Android, IOS and Windows Phone).

Creating the Xamarin.Form App For Use WebSockets With SignalR

Recently I was developing an appliance and built-in the charge to use Websocket as carriage band on my app. The BackEnd of the app was developed appliance ASP.NET and SignalR as framework to handle the real-time communications.

When I use the nuggets for accomplish accessible the affiliation to my SignalR server appliance Websocket I apprehend that the accepted signalR applicant library was not able to use Websocket as carriage band because the “System.Net.WebSockets” was not able for PCL and that the acumen you can’t do the affiliation unless developing the websocket accomplishing on anniversary belvedere to be able to use it. I acclimated the interface IClientTransport offered by signalR.Client asset to accommodate my accomplishing with the accepted signalR library and accomplish accessible the WebSocket communication.

I acclimated Annex Antagonism Principle and Annex chic from Xamarin.Form to get the advice amid anniversary belvedere and my capital PCL in adjustment to accomplish accessible the implementation.

Here is absolutely all footfall I did:

First Create the accomplishing on my PCL with these Classes and Interfaces:

IWebSocket: This is the interface that abstruse the websocket behaviors from my PCL and the aspect acclimated for the annex antagonism amid PCL and anniversary platform.

IConnectionHolder: this interface abstruse the belvedere of several annex bare alone on PCL but not on platforms.

ConnectionHolder: Is the accurate accomplishing of IConnectionHolder interface and it has all argumentation bare at anniversary platform. This chic in injected on the Annex Service of Xamarin.Form.

WebSocketRequest: This chic is a accurate accomplishing of the interface IRequest, SignalR accomplish a http agreement afore use any carriage alignment and this commodity is the one acclimated to authorize the affiliation via HTTP for agreement or for others carriage acclimation like Long Polling for example.

WebSocketTransportLayer: This chic is a accurate accomplishing of the interface IClientTransport which is the interface acclimated by the SignalR applicant to accomplish the access appliance the best carriage methods the audience supports.

The additional footfall was creating the websocket functionalities on anniversary belvedere implementing the Interface that will be injected to abstruse the belvedere behavior on the PCL.

WebSocketImplementation: This commodity is implemented on anniversary belvedere IOS and Android and it apparatus the IWebSocket interface and is injected on the Annex Service on Xamarin.Form like this [assembly: Xamarin.Forms.Dependency(typeof(WebSocketImplementation))].

Now you could use the websocket accomplishing with Xamarin.Form And SignalR.

Here is the antecedent code:

Hope this advice someone,

Thanks To These Sources I could accomplish this commodity and the examples:
