Silverlight SSL and WebService

I have recently modified my web service in IIS7 to use SSL. To do this, I have created a self signed certificate and applied that to my web service. I then added https bindings to my site in IIS. I have changed my clientaccesspolicy.xml file to allow https ->

 <domain uri="https://*" />

Whenever I try to call my service from my SL site I get the following error:

{System.Security.SecurityException: Security error. at System.Net.Browser.BrowserHttpWebRequest.InternalEndGetResponse(IAsyncResult asyncResult) at System.Net.Browser.BrowserHttpWebRequest.<>c__DisplayClass5.b__4(Object sendState) at System.Net.Browser.AsyncHelper.<>c__DisplayClass2.b__0(Object sendState)}

Does anyone know wha开发者_运维技巧t else I have to do to get this to work?
