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

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

extensible applications with MEF
navigation
• Frame displays a Page
<UserControl> <Frame Source=“authors.xaml”/>
authors.xaml
Page
books.xaml
Page
• 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()]
navigation
• 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
<UserControl> <Frame Source=“authors.xaml”/>

search
extensible applications with MEF
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
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”

extensible applications with MEF
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 )
essential MEF
Component(e.g. Visual Studio)
import(e.g DebuggerVisualizer)
Component(e.g. XML Visualizer)
export(e.g DebuggerVisualizer)
MEF Composition Engine
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
