When one use Windows7 to generate a WCF configuration file/ proxy that will generate some extra lines of code which will cause the problems in running the application. The extra lines generated are not supported in Silverlight/WPF environment. Those lines will look like <transport> <extendedprotectionpolicy policyenforcement = "Never" /> </transport> There are some limitations for silverlight & WPF to use custombinding. You can read an article related to this at http://msdn.microsoft.com/en-us/library/cc896571(VS.95).aspx Workaround: Those extra tags can be deleted or commented to run the application.
