This one always drives me nuts. When you add an area web project to an Mvc solution and go to debug mode you will see an extra web development server running. OK, don't want that, how to shut it off? Not too hard but its a deep google problem for me usually.

Here is how...

First click on the area web project, seen here in the MvcCms AddOns.Web folder. After it is highligted click properties down below, THIS IS NOT THE SAME IS RIGHT CLICK PROJECT PROPERTIES!



Then adjust the Always Start When Debugging property to false.
Now back to coding...
