Is it possible to use a service published from MapServer using ArcGIS API for Silverlight?
For example:
<esri:FeatureLayer ID="Schools Without Attendance Areas"
MouseEnter="FeatureLayer_MouseEnter"
MouseLeave="FeatureLayer_MouseLeave"
Visible="False"
Url="http://webaddress"
OutFields="SCHNAME, ADDRESS, PHONE, URL"/>
