I am new to asp.net. I am learning SignalR, going through this tutorial. I have created everything correctly as mentioned in the tutorial. Now when I ran the Console Application, ERROR –> “One or more errors occurred.” at hubConnection.Start().Wait();.(the console application is still running). Anyhow I tried even running the Web application which is not giving any error but the button broadcast doesnt do any action(I think it should). When I checked the code in Web application, I saw that one of the script source has green scribbles. Here is the Image.

enter image description here

Please explain what I am doing wrong..

Edit: I am using ASP.NET Development server.

Edit2: The errors I get in Google Chrome Console are:

Uncaught Error: SignalR: jQuery not found. Please ensure jQuery is referenced before the SignalR.js file. jquery.signalR-1.0.0-alpha2.min.js:10
Uncaught TypeError: Cannot read property 'signalR' of undefined hubs:17
Uncaught ReferenceError: $ is not defined

Answer: I just added reference of jQuery in my code above all the scripts and the “file not found” error is careless because it is running on server side.

The Link has also been updated with reference to jQuery

    The error message describes fully what the problem is:

    Uncaught Error: SignalR: jQuery not found. Please ensure jQuery is referenced before the SignalR.js file.

    You need to include jQuery.
