In this article, we’ll learn how to set dynamic versioning of JavaScript files in MVC. We will create a simple MVC project and call one JavaScript file from the View.

Step 1

Open Visual Studio and select “File” >> "New". Then, click on Project.

Step 2

Select “Templates” >> Visual C# >> Web then ASP.NET Web Application (.NET Framework), and put the appropriate project name. Click the “OK” button.

Step 3

And from here, select MVC project (you can select the project as per your requirement).

Step 4

Now, go to the .cs file where you want to create the extension method to append the versions. I'm creating a Helper class in which the below code will be added.

The class must be static and publicly accessible.

Here, we will create an HtmlHelper extension method which we can use anywhere in the project. Copy the below code and put it in your .cs file.

And that's it. We have created the extension method which we are going to use in View to append dynamic versioning.

Step 4

Go to the .cshtml file (your View) and add the below line.

@Html.IncludeVersionedJs is the extension method we created.

@Html.IncludeVersionedJs("YOUR FILE PATH")
