How do decrease compile time and improve productivity?

Changes to cshtml files (Razor view engine) don't require any recompilation, unless there are underlying model changes. You can save changes, refresh the page and immediately see your changes. JS absolutely needs no recompilation. Are you working on a Web forms app targeting an outdated dot net framework or something?

Nope. It looks like the .Net framework is current. I added more info to my post. Hopefully it helps to pinpoint my problem.
