SignalR Self Hosting With WCF Service and Clients Would be Desktop Users - wcf

Question

My Scenerio is that i need a SignalR self Hosted WCF Service that response and sends message to all connected users that came from Winform or WPF.
I have tried alot as follows:
I have Created WCF service with SignalR Self Hosting code as below which contains 3 Classes and 1 Interface.
namespace SignalRServiceClass
{
[ServiceContract]
public interface ISignalRServiceClass
{
[OperationContract]
string GetsMessage(string name);
[OperationContract]
void Configuration(IAppBuilder app);
[OperationContract]
void Send(string name, string message);
}
}
namespace SignalRServiceClass
{
public class SignalRServiceClass : ISignalRServiceClass
{
public string GetsMessage(string name)
{
return "Message From Service " + name + "!";
}
}
}
namespace SignalRServiceClass
{
class ClassHub : Hub
{
public void Send(string name, string message)
{
Clients.All.addMessage(name, message);
}
}
}
namespace SignalRServiceClass
{
class Startup
{
public void Configuration(IAppBuilder app)
{
// app.UseCors(CorsOptions.AllowAll);
// app.MapSignalR();
app.Map("/signalr", map =>
{
map.UseCors(CorsOptions.AllowAll);
var hubConfiguration= new HubConfiguration
{
EnableDetailedErrors=true,
EnableJSONP= true
};
map.RunSignalR(hubConfiguration);
});
}
}
}
And Secondly Winform Client. I am confused here that how to manage the client code here but i put some code for testing as below.
private void button1_Click(object sender, EventArgs e)
{
//MessageBox.Show(test.GetsMessage("This is the Test Message"));
var hubConnection = new HubConnection("http://localhost:50172/");
var serverHub = hubConnection.CreateHubProxy("MessageRecievingHub");
serverHub.On("broadCastToClients", message => MessageBox.Show(message));
hubConnection.Start().Wait();
}
Please guide me in this manner.
Your Help will be appreciated. I have tried and googled alot but in vain.
Thanks alot in Advance.

Answer 1

You do not want SignalR, you need XSockets WCF sample

Answer 2

SignalR and WCF don't interoperate in this way, and don't really need to. If you're using SignalR, there's no reason to use WCF- you can publish your hub on IIS or self-hosted (see the Getting Started tutorial and the Self-Host tutorial at asp.net/signalr), and connect to it with desktop or JavaScript/HTML clients.

Answer 3

You can easily create a .NET client application to communicate with your SignalR server - below is a simple WinForm .NET C# client that sends and receives a SignalR message:
namespace SignalrTestClient
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
async void Form1_Load(object sender, EventArgs e)
{
var hubConnection = new HubConnection("http://localhost:8080/");
IHubProxy hubProxy = hubConnection.CreateHubProxy("MyHub");
await hubConnection.Start();
hubProxy.On("addMessage", message => onData(message));
await hubProxy.Invoke("Send", "Hello SignalR Server!");
}
private void onData(string msg)
{
Console.WriteLine(msg);
}
}
}
In your SignalR server you just need the following hub class:
public class MyHub : Hub
{
public void Send(string message)
{
Console.WriteLine("Received a message from a client");
if (message.Contains("Hello")) {
Clients.All.addMessage("Well hello there client!");
}
}
}
It is also possible to create a C++ client for SignalR
