Answer 1

Go to (Examples.FirstProject -> Entities -> and in (Employee.cs, Product.cs, and Store.cs)

Change the Id property from:

public virtual int Id { get; private set; }

To:

public virtual int Id { get; set; }

Answer 2

Your type, Examples.FirstProject.Entities.Employee should have the ID property set to

public virtual int ID { get; set; }
