ASP.NET Development Server (“Cassini”) Stops Working

If you are suddenly unable to debug ASP.NET apps using the ASP.NET Development Server (aka “Cassini”), check your hosts file and make sure there’s an entry:

 127.0.0.1    localhost

There was an update on March 9, 2009 that might have removed this entry from the hosts file.  For more information, see the Visual Web Developer team blog.
