Проблема с CallerIdValue

[deniska]

Добрый день. Изучаю CRM 4.0. Взял пример автонумерации поля из книги. Подключил microsoft.crm.platform.callout.base.dll и microsoft.crm.sdk.dll. Возникла проблема с CallerId() и CallerIdValue.

             // Standard CRM Service Setup
             CrmService service = new CrmService();

             // We need a user that has global read access to the lead record so that we 
             // have the absolute maximum lead number. If all roles have global read privileges to 
             // the read value of the Lead, then this wouldn't be necessary.
             // For production, access this guid in a config file.
             Guid callerid = new Guid("A3222222-EEEE-AAAA-5555-000000000000");

            // Impersonate our global read user
              service.CallerIdValue = new CallerId();
              service.CallerIdValue.CallerGuid = callerid;

Возникают такие ошибки:
Error 1 CRM.Callout.CrmSdk.CrmService' does not contain a definition for 'CallerIdValue' and no extension method 'CallerIdValue' accepting a first argument of type 'Crm.Callout.CrmSdk.CrmService' could be found (are you missing a using directive or an assembly reference?)

Error 2 The type or namespace name 'CallerId' could not be found (are you missing a using directive or an assembly reference?)

Подскажите в чем проблема?
