I don\'t like to use IE for my system default web browser.
but
I do want to set IE as my browser in VS2010 because it works a little nicer for debug
The "World of VS Default Browser Switcher" vs2010 extension will select your desired browser for you and it works with MVC too. This is a free extension :)
