ASP.NET MVC SignalR错误

Question

I have an ASP.NET MVC application. When I start the application I get the error here:

SignalR: Connection must be started before data can be sent. Call .start() before .send()

No transport could be initialized successfully. Try specifying a different transport or none at all for auto initialization.

I am not at all using SignalR but I get that error related to SignalR. I am not sure why ...

But when I start my application, it loads browserlink file (please see below) which has references to SignalR. Is this creating problem? Please help.

typeof JSON!="undefined"&&(window._vwdJSON=JSON),typeof define!="undefined"&&(window._vwdDefine=define,define=null),typeof window.onbeforeunload!="undefined"&&(window._vwdonbeforeunload=window.onbeforeunload)

You may not be using SignalR, but yes, browser link uses SignalR.

According to the documentation :

Browser Link is enabled by default. There are several ways to disable it: In the Browser Link dropdown menu, uncheck Enable Browser Link.
