- 12. RoutingRoute engine parses url’s, extracts any data and sends it off to controllerCreate extremely customizable routesRoute table defines routes in global.asaxYou do not need to define a route to handle querystring parameters. They are automatically mapped.
- 13. Model The model is the representation of your data.Business Logic
- 14. ViewsNo Code behindAction 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
- 15. Html HelpersHtml 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.
- 16. Model BindingTakes data from an html form and creates an object.No need to write plumbing code
- 17. Best PracticesNever 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 helperAdd namespace to web.config so you don’t have to keep referencing it on each pageThe difference between routing name and class name.

Editor's Notes
- #7: Controller gets data from the model, Gives it to a view.Controller doesn’t care where model gets data, and likewise controller doesn’t care how the view renders.Each component only cares about itself. Easy to swap out.Benefits :Separation of ConcernsTestabilityEasy to modifyLack of ComplexityFlow:Request comes through. Controller class handles the request, fetching data from the model. Controller then sends that data to the View and the result is given to the framework for rendering
