Is it possible to开发者_运维技巧 check that an object is in the context before trying to delete that from context ?

Yes, something like:

var key = myContext.CreateEntityKey("Table", myObject);

if (myContext.TryGetObjectByKey(key, out otherObject))
{
     // delete or edit otherObject
}

But you find in /delete from the database, not (just) the context.
