Getting Started

By Rick Anderson and Scott Hanselman

This tutorial will teach you the basics of building an ASP.NET MVC Web application using Microsoft Visual

Studio 11 Express Beta for Web, which is a free version of Microsoft Visual Studio. Before you start, make sure

you've installed the prerequisites listed below. You can install all of them by clicking the following link: Web

Platform Installer.

If you're using Visual Studio 11 Beta instead of Visual Studio 11 Express Beta for Web , install the prerequisites

by clicking the following link: Web Platform Installer

A Visual Web Developer project with C# source code is available to accompany this topic. Download the C#

version.

What You'll Build

You'll implement a simple movie-listing application that supports creating, editing, searching and listing movies

from a database. Below are two screenshots of the application you’ll build. It includes a page that displays a list

of movies from a database:

The application also lets you add, edit, and delete movies, as well as see details about individual ones. All data￾entry scenarios include validation to ensure that the data stored in the database is correct.

Skills You'll Learn

Here's what you'll learn:

• How to create a new ASP.NET MVC project.

• How to create ASP.NET MVC controllers and views.

• How to create a new database using the Entity Framework Code First paradigm.

• How to retrieve and display data.

• How to edit data and enable data validation.

Getting Started

Start by running Visual Web Developer 11 Express Beta("Visual Web Developer" or VWD for short) and select

New Project from the Start page.

Visual Web Developer is an IDE, or integrated development environment. Just like you use Microsoft Word to

write documents, you'll use an IDE to create applications. In Visual Web Developer there's a toolbar along the

top showing various options available to you. There's also a menu that provides another way to perform tasks

in the IDE. (For example, instead of selecting New Project from the Start page, you can use the menu and

select File>New Project.)

Creating Your First Application

You can create applications using either Visual Basic or Visual C# as the programming language. Select Visual

C# on the left and then select ASP.NET MVC 4 Web Application. Name your project "MvcMovie" and then

click OK.

In the New ASP.NET MVC 4 Project dialog box, select Internet Application. LeaveRazor as the default view

engine.
