Starting from version 2.1, Entity Framework Core allows defining a parametrized constructor for a class and calls this constructor when creating a class instance.
Entity Developer allows adding parameters to such a constructor for assigning property values in the constructor when reading data from the database instead of calling a parameterless constructor and then assigning properties via their setters. This allows you, for example, to use read-only properties with private setters.
To add a parameter for a property to the constructor, simply set its Constructor Parameter property to True in the Properties window.
