    <p>There are some undocumented nuances with the latest version, in fact I was working through them today.</p> <p>First off you will not need the Code from Main, in the link you referenced. That is for using Signalr inside of a WPF app or Windows 8 app.</p> <p>The first issue that may or may not be an issue, is the use of HubNameAttribute, it may or may not be needed.<br> Without HubName the name of your hub should resolve to $.connection.chatHub</p> <p>The next part that you have already handled is the new namespaces on each hub.</p> <pre><code>chatHub.client - These are client defined methods, that the server may invoke. chatHub.server - These are server defined methods, that the client may invoke. chatHub.state - This is the state that gets sent to and from the server. </code></pre> <p>Now the uncaught error is something in the JavaScript not getting output correctly, most likely the hubs definition, as the hub variable is whats null. You need to verify under the covers that the hubs are coming back properly.</p> <pre><code>&lt;script type="text/javascript" src="~/signalr/hubs"&gt;&lt;/script&gt; </code></pre> <p>This should return a properly formatted jQuery ready block, that defines all the hubs and server methods for those hubs. Using a tool like <a href="http://www.fiddler2.com/fiddler2/" rel="nofollow">Fiddler</a> will help with this.</p> <p>I would also start using Chrome or Firefox w/Firebug, both have their advantages and disadvantages, but both will give you a network monitor and debugging facilities. Being able to catch unhandled exceptions has been a life saver trying to debug all things JavaScript.</p> <p>Hope this helps you on your quest to solve your outstanding issues.</p>

    1. COThanks for your response. Regarding code from controller, I removed it (**UPDATE3**), but still get error. I can't verify at the moment "~/signalr/hubs" (not at the working PC) but i remember trying yesterday, and it was an entire page with JavaScript, and in the end there were the definitions of the hubs. Also tried with/without HubName.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
