+1  Q: 

ASP .NET and IIS

Most of the developers i work with test their web apps by running them from visual studio, and use the built in web server of VS to display the pages. My question is when these apps are deployed to a IIS server would they behave any differently?

+2  A: 

One area where your app may behave differently is in the area of security. Because the built in web server is effectively running under your identity (i.e. you could be running as an admin user), when you deploy into a production environment life for your app may be very different.
