Let's start with an overview of what you'll learn in this course.

Prerequisites

To get the most from this course, you should feel comfortable with C#, ASP.NET MVC, Visual Studio, and the basics of Entity Framework. For more information about those topics, check out these Treehouse courses and workshops:

While it's not absolutely required, you'll also find it helpful to know something about relational databases and the SQL language. Check out this Treehouse course:

    Hi, my name is James. 0:04
    Entity framework or 0:07
    simply EF is a type of framework known as an object relational mapper or ORM. 0:08
    Using EF for your applications data access allows you to interact with your data using 0:15
    the set of entities and a database context clause. 0:19
    This keeps you from having to write SQL queries 0:23
    in order to interact directly with the database. 0:25
    In an earlier treehouse course we learned about the basics of EF, 0:28
    but we did that within the confines of console application. 0:32
    While that allowed us to keep the focus on EF, 0:36
    it didn't give us a realistic common use case. 0:38
    This course is designed to do just that. 0:43
    Show you how to use EF within a web application developed using Microsoft's 0:46
    asp.net MVC web framework. 0:50
    We'll start this course by seeing how to put our EF entities and 0:53
    database context classes into its own class library project. 0:57
    Then we will add an ASP.NET MVC project to our solution and 1:01
    update to use EF code in the class library. 1:05
    After updating our web app to retrieve and persist data. 1:08
    We'll look at some options for organizing our data access code. 1:11
    By the end of this course you will be able to use EF with ASP.NET MVC to 1:16
    create powerful data-driven web applications. 1:20
    Let's talk about how to get the most out of this course. 1:24
    I'm going to assume that you're already familiar with the basics of ASP.Net MVC, 1:28
    entity framework, and Visual Studio. 1:32
    If you're unfamiliar with any of those topics or maybe you need a refresher, 1:36
    check the teacher's notes for a list of Treehouse resources that can help. 1:41
    This course is designed to be highly interactive. 1:45
    Throughout, I'll be asking you questions and 1:48
    giving you hands-on coding exercises to complete on your own. 1:51
    But don't worry, you won't be left hanging. 1:54
    After you've had time to think about the question or complete an exercise, 1:57
    I'll share with you the answer or walk you through my solution. 2:02
    Also, I'd encourage you to follow along with each video. 2:05
    Write the code yourself as I'm writing it or just after and 2:09
    take the time to complete each exercise. 2:14
    Even if you aren't able to come up with the solution just the act of trying will 2:17
    help you to learn and retain the material Before we start working on setting 2:21
    up our solution, let's take a look at our web app in its finished form. 2:26
