I am using arcgis silverlight api

getFeature(objectid);

so i used WCF service to get the geometry but i found error that say

Type 'System.__ComObject' cannot be serialized

can you help quickly please

Thank you in advance

eventually I found a solution


using Query Task and pass in the where clause the filter like

query.where="objectid=17";


but when i need to save edit delete in sde use WCF service

that's set
