Попробуйте это может работать ...

Вы должны иметь расширенные свойства декларации на задаче создания свойства. просто добавьте x0020 в имеющихся пространствах. Код может выглядеть

SPTaskCreate_TaskProperties.ExtendedProperties["Start_x0020_Date"] = DateTime.Now; 

и не

SPTaskCreate_TaskProperties.ExtendedProperties["Start Date"] = DateTime.Now;
