  • 2. capabilities graphics browser need to know some or all media of this depending on what local machine you’re building layout network styling controls binding animation resources
  • 3. beyond capabilities rich internet ASP.NET Client Application Services application WCF Data Services WCF RIA Services navigation search extensible applications with MEF patterns frameworks *lots of other Silverlight frameworks, libraries, patterns out there – sorry if I missed your favorite
  • 4. where are we? ASP.NET Client Application Services WCF Data Services WCF RIA Services navigation search extensible applications with MEF
  • 5. ASP.NET Client App Services • ASP.NET services available to Silverlight clients ASP.NET membership roles profiles no specific client libraries here, just add a reference and make the call
  • 6. enough hot air, do a demo ASP.NET Services from Silverlight
  • 7. where are we? ASP.NET Client Application Services WCF Data Services WCF RIA Services navigation search extensible applications with MEF
  • 8. RESTful services (in general) Resources HTTP Request URL Res 1 VERB GET Res 2 Payload POST Res 3 PUT Res 4 XML JSON DELETE HTTP Response Status Payload XML JSON
  • 9. odata • Open Data Protocol ( odata ) – www.odata.org – published under the Open Specification Promise • Extends the AtomPub standard to add – an addressing scheme – a mechanism for schema – alternate representation – JSON – handling for concurrent updates – handling for batched requests
  • 10. WCF Data Services ( “Astoria” ) http://server/customers(‘alfki’)/Orders?$top=20 metadata Atom implementation of odata for the client and the server
  • 11. enough hot air, do a demo WCF Data Services from Silverlight
  • 12. WCF Data Services oData – There’s a Feed for That oData – How to Create a Feed for That To learn about OData go to Pablo/Mike’s talks Tuesday 11.30am Lagoon L Tuesday 3pm Breakers H ( check 2 B sure )
  • 13. where are we? ASP.NET Client Application Services WCF Data Services WCF RIA Services navigation search extensible applications with MEF
  • 14. WCF RIA Services DomainContext DomainService Stateful view + Bindable Data Stateless CRUD + App Logic class PlateViewDomainService class PlateViewDomainService EntityList<Restaurant> Books { get } Data Model + IQueryable<Restaurant> GetRestaurants() EntityQuery<Restaurant> GetRestaurantQuery() IQueryable<Restaurant> SearchRestaurant(string) EntityQuery<Restaurant> SearchRestaurantQuery(string) Metadata + Shared Code void AddRestaurant(Restaurant) class Restaurant Validation and authorization rules, Data members + Validation Application workflows, … Data Model class Restaurant Rich Internet Application Services Presentation Domain Network Data App Data Access Logic Context Service Logic Layer Under the covers infrastructure DB Note: Slide stolen from Brad Abrams
  • 15. WCF RIA Services • WCF RIA Services (fka .NET RIA Services) You’re building an application – You’re responsible for both server and client deep in business logic and semantics • WCF Data Services (fka “Astoria”) You’re exposing/acquiring data – You control one side or the other, not both – CRUD among arbitrary producers / consumers logic and semantics are invisible NB: Slide stolen from Brad Abrams
  • 16. enough hot air, do a demo WCF RIA Services
  • 17. WCF RIA Services Developing with WCF RIA Services Quickly & Effectively To learn about WCF RIA Services go to Nikhil Kothari’s talk Tuesday 1:30pm Lagoon H ( check 2 B sure )
  • 18. where are we? ASP.NET Client Application Services WCF Data Services WCF RIA Services navigation search extensible applications with MEF
  • 19. navigation Page • Frame displays a Page authors.xaml <UserControl> Page <Frame Source=“authors.xaml”/> books.xaml • navigation between pages – call Frame.Navigate() or set the Source property – or use a HyperlinkButton ( NavigateUri/TargetName ) • navigation history – call Frame.[Can]Go[Back()/Forward()]
  • 20. navigation Page • Frame displays a Page authors.xaml <UserControl> Page <Frame Source=“authors.xaml”/> books.xaml • navigation can integrate with the browser – enables hyperlinking into Silverlight content – requires a browser! – requires a hidden iframe on the hosting page – for top level Frames not nested frames
  • 21. navigation navigate: http://booksite/default.aspx#/authors/steinbeck navigate: /authors/steinbeck Frame UriMapper ContentLoader Uri MappedUri /authors/{author} /views/authors.xaml?surname={author} /{pageName} /views/{pagename.xaml} Asynchronously turns the URI into a Page or UserControl
  • 22. enough hot air, do a demo Navigation Framework in Silverlight 4
  • 23. where are we? ASP.NET Client Application Services WCF Data Services WCF RIA Services navigation search extensible applications with MEF
  • 24. search • search engines visiting a page with Silverlight – read robots.txt and sitemap – read/index the page title – read/index the <meta name=“description”/> – read/index the surrounding HTML ( if any ) – will not read XAP or dynamic Silverlight content • approach – alternate content in the <object/> tag – for both search engines & down-level clients
  • 25. enough hot air, do a demo offering alternate content to search note – I stole this demo, it comes from the WCF RIA Services Code Gallery and is called “Silverlight Store”
  • 26. WCF RIA Services Search Engine Optimization for MS Silverlight To learn more about SEO go to Brad Abrams’ talk Wednesday 12.00 Lagoon B ( check 2 B sure )
  • 27. where are we? ASP.NET Client Application Services WCF Data Services WCF RIA Services navigation search extensible applications with MEF
  • 28. extensible applications with MEF • the Managed Extensibility Framework – “an extensible framework for composing applications from a set of loosely-coupled parts discovered and evolving at run-time“ (mike) • versions – .NET Framework shipping with Silverlight 4 – .NET Framework 4 shipping with VS 2010 – Silverlight 3 & .NET Framework V3.5 Sp1 ( from source on CodePlex )
  • 29. essential MEF Compose • MEF discovers exports via catalogs – several “in box” catalogs plus many extensibility points – supports available exports changing at runtime • and/or can be handed component instances
