Silverlight White Screen Of Death Debugging

If you’re working in Silverlight and your app suddenly starts giving you the white screen of death, chances are there’s something wrong with the markup. Of course, since the white screen of death results in zero exceptions, sometimes it’s hard to track down what the problem is. Enter the Error Console in Firefox. If you get a WSOD, pop open Tools->Error Console in Firefox, scroll to the bottom of the list and you might be pleasantly surprised to find your problem described there.
