Problem
an unhandled exception occurred in the silverlight application

Solution
Just Enable the Security Validation in the central administration from Manage Web Applications --> General Settings (from ribbon).

Silverlight Application is unable to connect to the WCF endpoint configured by the product for enabling Client Object Model, if Security validation is set to Off.
