Setting this property to false improves performance at retrieval time, because there are fewer items to track.
An exception is thrown:
If the property is set to false after a query has been executed.
For more information, see the Valid Modes section in DataContext.
If the property is set to false and SubmitChanges is called.
If ObjectTrackingEnabled is false, DeferredLoadingEnabled is ignored and treated as false. In this case, the DataContext is read-only.
If ObjectTrackingEnabled is true, DeferredLoadingEnabled is false. In this case, DataContext allows you to load an object graph by using LoadWith directives, but does not enable deferred loading.
