silverlight cann't display a Arcgis map service,already copy the file

XINGMIN

i have publiched an ArcGis map service using Arcgis server installed on

my own computer,the map service runs correctly in the Arcgis Server Manager

(can see the little map when you expand the service node).But a new-builded

silverlight application can not display the map!i have already copy the

fileclientaccesspolicy.xml to the web server(IIS) root dictionary:

C:\inetpub\wwwroot,the following is the XAML:
<UserControl x:Class="SilverlightApplication.MainPage"   
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"    
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"    
  xmlns:esri="http://schemas.esri.com/arcgis/client/2009">
  <Grid x:Name="LayoutRoot">
    <esri:Map x:Name="MyMap" >
      <esri:ArcGISTiledMapServiceLayer ID="MyMapLayer"   
        Url="http://minxing/ArcGIS//services/binhai/MapServer"/>
    </esri:Map>
  </Grid>
</UserControl>

When you hit the rest end point

http://yourservername/arcgis/rest/services

and click on the service you published

Then click View In ArcGIS JavaScript

Can you see the map with that?  Can you view the source code?  If you can then I think it might be your silverlight app code.
