Accessing from outside of a controller

[MattHartz]

Hi, I'm trying to access my websockets from outside in another service. Is there a way similar to how SignalR allow you to access Hubs via IHubContext?

Thanks!

Take a look at this sample here

Basically, you can have a messageHandler injected via constructor injection in any class you need.

hmm, well for my example, i'm utilizing Service Fabric which has this code in Program.cs. Which I want to pass the handlers into the constructor of "Service", but at this point Startup.cs has yet to be called therefore the handlers have yet been stored in the IOC container... does that make sense?

private static void Main()
{
	try
	{
		// The ServiceManifest.XML file defines one or more service type names.
		// Registering a service maps a service type name to a .NET type.
		// When Service Fabric creates an instance of this service type,
		// an instance of the class is created in this host process.

		ServiceRuntime.RegisterServiceAsync("ServiceType",
			context => new Service(context)).GetAwaiter().GetResult();

		ServiceEventSource.Current.ServiceTypeRegistered(Process.GetCurrentProcess().Id, typeof(NotificationAPIService).Name);

		// Prevents this host process from terminating so services keeps running. 
		Thread.Sleep(Timeout.Infinite);
	}
	catch (Exception e)
	{
		ServiceEventSource.Current.ServiceHostInitializationFailed(e.ToString());
		throw;
	}
}

Would i need to do something like such inside of Program.cs?

public static void Main(string[] args)
    {
        //setup our DI
        var serviceProvider = new ServiceCollection()
            .AddLogging()
            .AddSingleton<IFooService, FooService>()
            .AddSingleton<IBarService, BarService>()
            .BuildServiceProvider();

        //configure console logging
        serviceProvider
            .GetService<ILoggerFactory>()
            .AddConsole(LogLevel.Debug);

        var logger = serviceProvider.GetService<ILoggerFactory>()
            .CreateLogger<Program>();
        logger.LogDebug("Starting application");

        //do the actual work here
        var bar = serviceProvider.GetService<IBarService>();
        bar.DoSomeRealWork();

        logger.LogDebug("All done!");

    }
