    <p>I came across with same issue couple days ago. That took my 2 days to find solution and resolve it. After some serious investigate the problems root cause was the signalr dependency resolver that I set customly. </p> <p>At the end I found <a href="https://github.com/SignalR/SignalR/wiki/Extensibility" rel="noreferrer">this link</a> and that was saying this:</p> <blockquote> <p>Replacing the DependencyResolver</p> <p>You can change the DependencyResolver to use your DI container of choice by setting GlobalHost.DependencyResolver.</p> <p><strong>NOTE: DO NOT override the global resolver in PreApplicationStart, it will not work, or it'll work only sometimes. Do it in PostApplicationStart (using WebActivator) or in Global.asax.</strong></p> </blockquote> <p>The important place here the NOTE. Of course after signalr 2.0 this documentation become <strong>deprecated</strong>. So I mixed some of here with the new SignalR API. In new SignalR API not using WebActivatorEx anymore. OwinStartup preferred instead of WebActivator.</p> <pre><code>[assembly: OwinStartupAttribute(typeof(YourNamespace.Startup))] namespace YourNamespace { public partial class Startup { public void Configuration(IAppBuilder app) { //IoC container registration process UnityConfig.RegisterComponents(); UnityConfig.Container.RegisterType&lt;AHub, AHub&gt;(); HubConfiguration config = new HubConfiguration(); config.EnableJavaScriptProxies = true; //You should remove your dependency resolver code from here to Global.asax Application_Start method. Before setting the MVC properties. //config.Resolver = new SignalrDefaultDependencyResolver(UnityConfig.Container); // your dependency resolver // app.MapSignalR(config); } } } </code></pre> <p>And in your global.asax </p> <pre><code>namespace YourNamespace { public class MvcApplication : System.Web.HttpApplication { protected void Application_Start() { //Here your SignalR dependency resolver GlobalHost.DependencyResolver = new SignalrDefaultDependencyResolver(UnityConfig.Container); //other settings goes on AreaRegistration.RegisterAllAreas(); GlobalConfiguration.Configure(WebApiConfig.Register); FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters); RouteConfig.RegisterRoutes(RouteTable.Routes); BundleConfig.RegisterBundles(BundleTable.Bundles); } } } </code></pre> <p>I dont want to send all the code here, for showing up the real problem.</p> <p>So for me everything works fine for now. Dependency injection also works too. But the bad part is everywhere that I searched David Fowler was saying "Its by design". I started to think is this design really a necessary or a mistake.</p> <p>Hope it helps somebody else who makes research for same problem.</p>

    1. COI appreciate your answer. I don't understand it however. Why would I want to replace the DependencyResolver. The documentation on calling client methods from outside the hub (http://www.asp.net/signalr/overview/signalr-20/hubs-api/hubs-api-guide-server#callfromoutsidehub) says nothing about that. None of the examples I've cited above mention it either. My code above looks correct to me. Do you see something incorrect with it?

    2. COOk, my answer was all about assuming that you were using dependency injection. Before answer here, I checked your example links and in your second link OP was talking about dependency resolution. So please correct me if you are not using dependency resolver. And also there is one more thing here. The link which you gave me in above comment use also dependency resolver. An also that StockTickerHub is singleton instance. So it always gives you same thing back. But in our case dependency resolver gives different instances. If you want I can update my answer with some more code.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
