                                                     select c;

Hi asid,

To clear the DomainContext's cached instance, please pass LoadBehavior to Load method like below

 LoadOperation<Customer> loadOp = this._customerContext.Load(query, LoadBehavior.RefreshCurrent , false);

For details, please refer to
