Rejuicer is a great new minifier for ASP.NET that's getting a lot of buzz: http://rejuice.me

It is configured as a HTTP module & performs minification at run-time (once) and caches the output.

It:

• Has a fluent interface for configuration
• Allows you to specify files to minify with wildcard rules
• Runs on Windows Azure
• Somewhat magically turns itself off in development environments, so you can debug your original javascript code (not minified).

The configuration (done on ApplicationStart in global.asax.cs) is as simple as:

OnRequest.ForJs("~/Combined.js")
            .Compact
            .FilesIn("~/Scripts/")
              .Matching("*.js")
            .Cache
            .Configure();
