Getting Started

Start by running Visual Studion 2010 Ultimate and select New Project from the Start page.

Create Your First Application in ASP.NET MVC3 Web Application

In the New ASP.NET MVC 3 Project dialog box, select Internet Application. Leave Razor as the default view engine or you select ASPX View.

Now Click OK. Visual Studio Used Default templete for the ASP.NET MVC project which you created. Now you are working on this application.

Create The Model For The MVCStudent Application

Go To Solution Explorer > App_Data > Add > Existing Item explorer to locate the Student.mdf file. Select it and click Add.
Now Go To Solution Explorer > Models > Add > New Item Now Select ADO.Net Entity Data Model.
Change the name of the model to Model1.edmx and click Add.

In the Choose Model Contents window, select Generate from database and then click the Next button.
On the Choose Your Data Connection page, select Student.mdf in the data connection drop down and click Next.

Check the Tables checkbox in Choose Your Database Objects (shown in Figure 3) and click Finish.

Visual Studio will open the Entity Data Model designer with the new model,

From the Debug menu, select Start Debugging.

On Keyboard Shortcut Press F5 to Start Debugging.

Adding a Controller

The AddView dialog will open with the View name already set to Index.

Check the Create a strongly typed view checkbox.

Click Add to complete the view creation.

You’ll need to change that to start with the Index View of the Blog controller instead.

Open the global.asax file from Solution Explorer.

Modify the MapRoute call to change the value of controller from “Home” to “Student”.

Now Run The Application

Now run your application and see you can create, edit, detail,
