The type of the property to be configured.

Remarks

When adding a new property, if a property with the same name exists in the entity class then it will be added to the model. If no property exists in the entity class, then a new shadow state property will be added. A shadow state property is one that does not have a corresponding property in the entity class. The current value for the property is stored in the ChangeTracker rather than being stored in instances of the entity class.
