Bundling in ASP.NET MVC already has a built-in mechanism for handling these type of cache-busting scenarios for release builds as per the "Bundle Caching" section of this documentation :

As long as the bundle doesn't change, the ASP.NET application will request the AllMyScripts bundle using this token. If any file in the bundle changes, the ASP.NET optimization framework will generate a new token, guaranteeing that browser requests for the bundle will get the latest bundle.

This features uses a token within the querystring called v to indicate current "version" of the bundle that looks like :

v=r0sLDicvP58AIXN_mc3QdyVvVj5euZNzdsa2N1PKvb81

This functions as a unique identifier for the particular build and as long as nothing in the bundle was changed, it will continue to use it, otherwise a new one would be generated to "bust" any existing caching.

For Non-Release Builds

If you needed to handle this in non-release builds, then I believe you could set the EnableOptimizations property to true to always handle this :

BundleTable.EnableOptimizations = true;
