Remarks

You should only use this method for attributes you know were requested in the query that retrieved the entity. You can use Entity.Contains to check whether the entity instance includes the attribute.

When an entity instance does not include the attribute specified using the attributeLogicalName parameter this method will return null or the default value for the type rather than throw an exception. You should not assume that the entity includes the attribute. It may not be included if the code that retrieved the attribute didn’t request it.
