I have a silverlight app that is connecting to a WCF self hosted service. Originally it was just using HTTP and it worked fine in and out of browser. I recently added Transport security for SSL and it its using a self signed certicate created by makecert. The CA is added to my trusted CA's list. The application works fine in browser; however, out of browser it does not appear to be working at all. It seems to be having issues negotiating the SSL connection.
