It turns out that if i call saves twice in program within millisecond, i will see the error. Now I am checking if there is already save in progress, then wait for second save to complete.

See if you can identify any of the entities causing the concurrency violation:

All my updates are done via ideaBlade. I am not explicitly attaching or detaching entities, plus all the fields in EntityManager are set to CuncurrencyMode="None". If  I had any of the fields  CuncurrencyMode set to Fixed then this error would have made sense.

Hello,
I am keep on seeing following exception when saving in silverlight.:
"Store update, insert, or delete statement affected an unexpected number of rows(0). Entities may have been modified or deleted since entities were loaded. Referesh ObjectStateManager entries".
 
This error usually happens if I were to save multiple objects. It saves successfully to database, but when checking for error once the Async save has been completed there is an exception. I also noticed this message when I am the only updating records, so i don’t think this would be concurrency issue when though it looks like.   Does anyone know what could be the underlying issue?
 
Thanks,
Amit
