将Web API连接到SQL Server

Question

I am new to ASP.NET and I am creating a Web API using sort of code first. I have model class call gender and defined as follow

public class Gender
{
    public int Id { get; set; }
    public string Description { get; set; }
}

I decided to create a new folder call DBContext and inside will defined all my DBContext , so for the gender class I have created GenderDb and look like follow:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Data.Entity;

namespace BackAPI.Models
{
    public class GenderDB : DbContext
    {
       // not define yet
    }
}

However I am having an issue however with DbContext not being defined, apparently I am supposed to use Entity Framework, however I want to create my database not through Visual Studio, but using SQL Server 2014 Express.

I did add my data connection and can see that I created a table in SQL Server, however how do I fix DbContext , if I use EF wouldn't that just create it locally and that not what I want

Answer 1

Entity Framework, along with Migrations, will help you here.
