Code First Approach Using Data With Stored Procedure

Introduction

In this article we will see how to access a SQL Server database with the Entity Framework Code First Approach using data and later we will see how to create a procedure using the Fluent API.

Step 1: Create console application

Employee.cs

  1. using System;  
  2. using System.Collections.Generic;  
  3. using System.ComponentModel.DataAnnotations;  
  4. using System.ComponentModel.DataAnnotations.Schema;

  13.        public Employee()  
  14.        {  
  15.        }

  18.        [DatabaseGenerated(DatabaseGeneratedOption.Identity)]  
  19.        public int Id { getset; }

  21.        public string LastName { getset; }

  24. }

Employeecontext.cs

  1. using System;

  9. {  
  10.     public class EmployeeContext : DbContext  
  11.     {  
  12.         public EmployeeContext()  
  13.             : base("EmployeeConn")  
  14.         {  
  15.             Database.SetInitializer<EmployeeContext>(new CreateDatabaseIfNotExists<EmployeeContext>());  
  16.         }  
  17.   
  18.         public DbSet<Employee> Employees { getset; }  
  19.   
  20.         protected override void OnModelCreating(DbModelBuilder modelBuilder)  
  21.         {  
  22.   
  23.             modelBuilder.Entity<Employee>()  
  24.                 .MapToStoredProcedures();  
  25.         }  
  26.     }  
  27. }

Web.config

  1. <connectionStrings>  
  2.     <add name="EmployeeConn"  
  3.     connectionString="Data Source=WIN-B4KJ8JI75VF;Initial Catalog=EmployeeDB;Integrated Security=true"  
  4.     providerName="System.Data.SqlClient"/>  
  5.   </connectionStrings>

Program.cs

  1. using System;  
  2. using System.Collections.Generic;  
  3. using System.Linq;  
  4. using System.Text;  
  5. using System.Threading.Tasks;  
  6.   
  7. namespace CodeFirstApproach_SPApp  
  8. {  
  9.     class Program  
  10.     {  
  11.         static void Main(string[] args)  
  12.         {  
  13.             EmployeeContext empContext = new EmployeeContext();  
  14.             Employee emp = new Employee()   
  15.             {   
  16.                 FirstName = "Haney",   
  17.                 LastName = "Jow"  
  18.             };  
  19.             empContext.Employees.Add(emp);  
  20.             empContext.SaveChanges();  
  21.             Console.WriteLine("Inserted");  
  22.             Console.ReadKey();  
  23.         }  
  24.     }  
  25. }

The following shows the output of the application:
