What is the MVC paradigm?
Controllers and Action Methods

A new web development framework that allows you to develop web applications on the Microsoft stack using an MVC Architecture.
Is NOT a replacement for traditional ASP.NET web forms.
Web Forms vs MVC
Current Version is MVC3.
MVC2 and MVC3 are extension of MVC1.
MVC1 and MVC2 - .NET Framework 3.5 & 4.0
MVC3 4.0 ONLY
Visual Studio Tooling Support
Convention over configuration
What is ASP.NET MVC

What is MVC?

Why should I use ASP.NET MVC?
Testability
Model Binder is awesome!
No Viewstate
SEO friendly url’s
Complete control over Html output
Easier integration with Jquery
Better Separation of Concerns

ASP.NET Web Forms
Traditional urlhttp://www.yoursite.com/admin/menu.aspx

ASP.NET MVC
http://www.yoursite.com/admin/menu
Admin is not a folder, but a class called AdminController
Menu is not a file, but a Method in the AdminController Class

Routing
Route engine parses url’s, extracts any data and sends it off to controller
Create extremely customizable routes
Route table defines routes in global.asax
You do not need to define a route to handle querystring parameters. They are automatically mapped.

Model
The model is the representation of your data.
Business Logic

Views
No Code behind
Action methods by default call views with the same name. (Convention over configuration)
Views are not tied to a specific action method or controller.
Views should be dumb (shouldn’t contain any application logic, only rendering logic)
Views can be strongly typed

Html Helpers
Html helpers are extension methods that generate html. @Html.TextBox(“Name”,”Bob”)
Html helpers are NOT controls, they simply generate html markup (strings)
You can create your own Html Helper.

Model Binding
Takes data from an html form and creates an object.
No need to write plumbing code

Best Practices
Never include a hard reference in the view(eg <script src=“../js/jquery.js”></script>)instead use url.content like so<script src=“<%=Url.Content(“~/js/jquery.js”)%>”></script>)
Never have big if then else in view, put it in an html helper
Add namespace to web.config so you don’t have to keep referencing it on each page
The difference between routing name and class name.
