I am new to Silverlight so please bare with me. I am testing the samples and they are excellent but when i try to in corporate my data i can't seem to get it to work. I am using the sample "Simple" under feature layer because i have some ArcGIS map services. This is my current code, so any help would be great thanks. We currently have some layers in ArcGIS server map services and varified the url and Map layer IDs through ArcGIS Services Directory.
