Today I had to make a connection between an old windows service and SignalR client. After tackling for an hour I decided to reference the Microsoft.AspNet.SignalR.Client library to my web service project and use it like below by overriding the OnStart method, actually I created the SignalR hub connection in the web service method:
1 2 3 4 5 6 7 8 9 | protected override async void OnStart(string[] args) { var hubConnection = new HubConnection("http://www.MySignalRDomain.com/signalr", useDefaultUrl: false); IHubProxy myProjectHub= hubConnection.CreateHubProxy("myProjectHub"); await hubConnection.Start(); await myProjectHub.Invoke("HiToYou", "an invoked message, for example"); } |
And in the SignalR service, I created the target hub to get the string ("an invoked message, for example") from the web service in HiToYou method :
1 2 3 4 5 6 7 8 9 | public class myProjectHub: Hub { public void HiToYou(string message) { Clients.All.addNewMessageToPage(message); } } |
Needless to say, if you are using OwinStartup, you need to register SignalR middleware:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 | using Microsoft.Owin;using Owin; [assembly: OwinStartup(typeof(MyApplication.Startup))]namespace MyApplication{ public class Startup { public void Configuration(IAppBuilder app) { app.MapSignalR("/signalr", new HubConfiguration()); } }} |
Hope it would be useful!
