The ASP.NET Web optimization framework provides services to improve the performance of your ASP.NET Web applications.

Current services provided by the framework include:

  • bundling - combining multiple scripts or style resources together into a single resource, and thereby requiring browsers to make fewer HTTP requests
  • minification - making scripts or styles smaller using techniques such variable name shortening, white space elimination, etc.

Additionally, the framework has multiple extensibility points, enabling you to add new services over time. The easiest way to install the framework is via its NuGet package.
