Bundle.config is a file created in default by MVC that is used to write the bundling code.

However, there are quite a few limitations on what you can specify in the Bundle.config. For instance, you can't specify any custom transformations to be applied to individual items or bundles. The only bundle properties that you're able to set are the Path, CdnPath, and CdnFallbackExpression. You can't set the Orderer or EnableFileExtensionReplacements properties. You don't have a way to include a directory including all subdirectories (like you can with the IncludeDirectory method). Basically, there's a LOT of functionality that is only available through the back-end code. Granted, a lot of this you could set by using back-end code to retrieve a bundle that was defined in the bundle.config, and then manipulating. But if you're going to do that, you might as well create the bundle in the back-end, also.

Why do we use bundling and minification?
Bundling and minification primarily improve the first page request load time. Once a webpage has been requested, the browser caches the assets (JavaScript, CSS and images) so bundling and minification won't provide any performance boost when requesting the same page, or pages on the same site requesting the same assets. If you don't set the expires header correctly on your assets, and you don't use bundling and minification, the browsers freshness heuristics will mark the assets stale after a few days and the browser will require a validation request for each asset. In this case, bundling and minification provide a performance increase after the first page request. For details, see the blog Using CDNs and Expires to Improve Web Site Performance.
How long does a bundle last?
Bundles set the HTTP Expires Header one year from when the bundle is created. If you navigate to a previously viewed page, Fiddler shows IE does not make a conditional request for the bundle, that is, there are no HTTP GET requests from IE for the bundles and no HTTP 304 responses from the server. You can force IE to make a conditional request for each bundle with the F5 key (resulting in a HTTP 304 response for each bundle). You can force a full refresh by using ^F5 (resulting in a HTTP 200 response for each bundle.)

What is bundle in web development?
Bundling combines multiple files into a single file. Bundling reduces the number of server requests that are necessary to render a web asset, such as a web page. You can create any number of individual bundles specifically for CSS, JavaScript, etc. Fewer files mean fewer HTTP requests from the browser to the server or from the service providing your application. This results in improved first page load performance.
Why do we need bundling and minification?
Bundling and minification primarily improve the first page request load time. Once a web page has been requested, the browser caches the static assets (JavaScript, CSS, and images). So, bundling and minification don't improve performance when requesting the same page, or pages, on the same site requesting the same assets.
Is ASP.NET Core compatible with WebOptimizer?
ASP.NET Core is compatible with WebOptimizer, an open-source bundling and minification solution. For set up instructions and sample projects, see WebOptimizer. ASP.NET Core doesn't provide a native bundling and minification solution.
Does bundling and minification improve performance?
So, bundling and minification don't improve performance when requesting the same page, or pages, on the same site requesting the same assets. If the expires header isn't set correctly on the assets and if bundling and minification isn't used, the browser's freshness heuristics mark the assets stale after a few days.
