How to call the WCF service from silverlight application?

Can you help me get the Silverlight Facebook application fixed on my Mac?

• Can anyone help me get the Silverlight Facebook app to work again on my Mac? I cannot get the Facebook Silverlight (or is it Silverlight Facebook... but I digress) application to work on my Mac. One day it worked. The next day it didn't. I've uninstalled both the silverlight plugin (framework?) and the Facebook app to no avail. I've also tried to parse some geeky suggestions online. When I launch it, all that shows up is a white screen. I really like it. It changes the way I use Facebook. Thanks in advance

• Answer:

  I'm totally not a mac person, nor have I ever used facebook, let alone a silverlight interface for said facebook, BUT, I'll bet there's something hanging around in ~/Library/Application Support Try uninstalling both things, then open a finder window, press Apple+Shift+G and type ~/Library/Application Support ... Then delete anything in there that says facebook or silverlight, and again try installing both things.
