Get Rid of the Old ASPX View Engine

Peter didn't bother doing any performance testing but he believes that this change has just got to speed up your ASP.NET MVC application.

File this tip under the "I bet everyone knew this but me" heading: A couple of months ago, I was somewhat surprised to discover that my ASP.NET MVC applications were loading two view engines: The RazorEngine that I actually use and the original WebFormViewEngine from ASP.NET MVC 1.0 (because I came to ASP.NET MVC on or about version 3, I never used that engine). Furthermore, ASP.NET was occasionally referring to that engine, throwing away some cycles.

I decided to remove that engine and keep just the Razor engine. So far, I've had no problems. If you want to do that also, here's the code you should add to the Application_Start method in your Global.asax file:

ViewEngines.Engines.Add(New RazorViewEngine)

I'm not suggesting that you'll see some enormous speed gain, but I have to believe it's going to save me some cycles.
