* 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.

* 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
*DEMO
*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.
