Remarks
Backing fields are normally found by convention. This method is useful for setting backing fields explicitly in cases where the correct field is not found by convention.
By default, the backing field, if one is found or has been specified, is used when new objects are constructed, typically when entities are queried from the database. Properties are used for all other accesses. This can be changed by calling UsePropertyAccessMode(PropertyAccessMode).
See Backing fields for more information and examples.
