In this video we will discuss, creating a reusable Models class library project. This project can then be reused with a razor pages web application, windows application, web api etc. It works cross platform.


Creating .Net Standard Class Library Project

In the Solution Explorer, right click on the solution and select Add - New Project.


In the Add a new project dialog, type Class Library. You will see several different class library projects. We will discuss the differences and when to use one over the other in our upcoming videos. The one we want is .NET Standard Class Library.



On the next screen provide a name for the project. Since this project is going to contain the models, I am going to name it RazorPagesTutorial.Models.

Finally, click Create.

Creating the models

In this project, we will be performing CRUD (i.e Create, Read, Update and Delete) operations against Employees. So we need an Employee class and Dept enum.

Dept Enum

namespace RazorPagesTutorial.Models
{
    public enum Dept
    {
        None,
        HR,
        IT,
        Payroll
    }
}

Employee Class

namespace RazorPagesTutorial.Models
{
    public class Employee
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public string Email { get; set; }
        public string PhotoPath { get; set; }
        public Dept? Department { get; set; }
    }
}

Next, we need to create services that retrieve data from an underlying data source such as a SQL Server database. We will create these services also in a separate reusable .Net Standard class library project.
