2. 2 ASP.NET MVC Scott Hanselman Senior Program Manager Microsoft

3. 3 Hello Cheesy Scott Hanselman Senior Program Manager Microsoft

4. 4 What’s the Point? This is not Web Forms 4.0 It’s about alternatives. Car vs. Motorcycle. Flexible Extend it. Or not. Fundamental Part of System.Web and isn’t going anywhere. Plays Well With Others Feel free to use NHibernate for Models, Brail for Views and Whatever for Controllers. Keep it simple and DRY

5. 5 Goodness – Driving Goals Maintain Clean Separation of Concerns Easy Testing Red/Green TDD Highly maintainable applications by default Extensible and Pluggable Support replacing any component of the system

6. 6 Goodness – Driving Goals Enable clean URLs and HTML SEO and REST friendly URL structures Great integration within ASP.NET All the same providers still work Membership, Session, Caching, etc. ASP.NET Designer Surface in VS2008

7. It’s still ASP.NET Providers still work Membership, Caching, Session, etc. Views leverage.aspx and.ascx But they don’t have to if you don’t want them to Within System.Web namespace Feature Sharing

8. 8 3 Circles Model ControllerView

9. 9 A Little More Detail ModelController View Browser requests /Products/ Route is determined Controller is activated Method on Controller is invoke Controller does some stuff Renders View, passing in custom ViewData URLs are rendered, pointing to other Controllers

16. 16 Routing Scott Hanselman Senior Program Manager Microsoft

17. 17 Extensibility Views Controllers Models Routes …are all Pluggable

18. 18 ViewEngines View Engines render output You get WebForms by default Can implement your own MVCContrib has ones for Brail, Nvelocity NHaml is an interesting one to watch View Engines can be used to Offer new DSLs to make HTML easier Generate totally different mime/types Images, RSS, JSON, XML, OFX, VCards, whatever.

19. 19 Views <%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" AutoEventWireup="true" CodeBehind="List.aspx" Inherits="MvcApplication5.Views.Products.List" Title="Products" %> ( )

20. 20 NHaml – Extreme Views %h2= ViewData.CategoryName %ul - foreach (var product in ViewData.Products) %li = product.ProductName.editlink = Html.ActionLink("Edit", new { Action="Edit", ID=product.ProductID }) = Html.ActionLink("Add New Product", new { Action="New" }) - foreach (var product in ViewData.Products) %li = product.ProductName.editlink = Html.ActionLink("Edit", new { Action="Edit", ID=product.ProductID }) = Html.ActionLink("Add New Product", new { Action="New" })

21. 21 Testing Controller Actions No requirement to test within ASP.NET runtime. Use Moq or RhinoMocks or TypeMock Create Test versions of the parts of the runtime you want to stub

25. Choosing Between The Two

26. You Might be an MVC if… You want full control over markup You want a framework that enforces separation of concerns TDD/Unit Testing is a priority for you Control abstractions get in your way more than they help You like writing Javascript

27. You Might be a WebForm if… You like programming against controls that encapsulate UI and logic You like the WYSWIG designer and would rather avoid angle brackets You like keeping logic on the server rather than hand writing Javascript
