jQuery intellisense support helps a lot while programming with jQuery. By default Visual Studio doesn't provide us the jQuery intellisense support. We can enable the jQuery intellisense support in Visual Studio with MVC Razor by adding vsdoc.js file to your view like as :
The above if-statement prevents the rendering of script tag into the html source code and it used only by the Visual Studio for jQuery intellisense support. To check jQuery intellisense type the $ or $( between your $(document).ready(function() function and you can see the intellisense as shown in fig.
In MVC Razor, there is no central place to add the reference to the vsdoc.js file. We need to add this code line to each every view separately to enable the IntelliSense support for jQuery.
