A complete look into the bundling and minification framework available in the ASP.NET web optimization library. Learn how to efficiently optimize your website resources and assets without comprising the way you want to develop. ASP.NET makes bundling and minification incredibly easy and leaves no reason not to ensure your web application is fully optimized. Walk through basic optimization setup against a demo application in both Web Forms and MVC. Then, work to enhance the demo application by adapting the bundling framework for ignoring files, ordering files, and adding CDN scripts with a fallback. You will see how to begin extending the optimization library with your own custom transforms to harness great flexibility. We will take customizations a step further and consider using custom bundles to consolidate and inject resources, enumerations and templates to the client. Finally, we will dive into unit testing your optimization configurations and extensions and the importance of doing so in a team environment.
