  2. From Rich to ReachSilverlight 2 and IE8

  3. dedicated hardware+software desktop app (WPF/XBAP) browser enriched(silverlight) ASP.NET AJAX HTML + JavaScript

  4. The Rich Silverlight 2

  5. Media: Supported Media File Formats Video Formats WMV (VC-1, v.7, v.8, and v.9) Audio Formats WMA (v.7, v.8, and v.9), MP3 WMA 10 Pro (new in SL2)

  6. More Media Adaptive Streaming • Encode multiple bitrates • Silverlight switches based on CPU and Network load • Extensible (BYO algorithm) DRM • DRM9/10 • PlayReady Server side playlists

  7. Media: Bitrate Throttling • No bandwidth control with traditional HTTP downloads • Drop-off point in videos: • Microsoft.com ~ 40% • Typical video site < 20%

  8. Media: Bitrate Throttling

  9. Controls: Built-In

  10. Controls: Silverlight Toolkit AutoCompleteBox NumericUpDown Viewbox Expander • ImplicitStyleManager • Charting • TreeView • DockPanel • WrapPanel • Label • HeaderedContentControl • HeaderedItemsControl • http://www.codeplex.com/Silverlight/

  11. UI Customization • Silverlight is designed for UI flexibility • Customize the look of an applicationwithout changing it’s behavior • 2 levels of customization: • Styling: Small visual changes on an element (Font, background color, etc) • Skinning: Replacing an element’s entire visual tree

  12. Theming: Silverlight Toolkit • http://www.codeplex.com/Silverlight/

  13. Layout Controls • Layout containers • Canvas, Grid, StackPanel, Border • Layout properties • Width, MinWidth, MaxWidth, ActualWidth • Height, MinHeight, MaxHeight, ActualHeight • Margin and Padding

  14. Network • Cross Domain Policy Support (Silverlight and Flash policy files) • Socket Support • Background network treading (asynchronous data) • Socket and HTTP • Duplex Communication (ServerPush) • Using WCF • Instant Apps, Monitoring, Chat etc • ADO.NET Data Services • ADO.NET Data Services ships in .NET 3.5 SP1 • Silverlight has client access bits (REST)

  15. Asynchronous Support Asynchronous web services supported Start the async web service call proxy.BeginGetTransactionList( newAsyncCallback(OnTransactionDataLoaded), null); Handle the web service completion event private void OnTransactionDataLoaded(IAsyncResultiar) { transactionList = proxy.EndGetTransactionList(iar).ToList(); }

  16. XmlReader & XmlWriter • Core XML reading & writing capabilities • LINQ to XML Initialisethe reader XmlReaderxr = XmlReader.Create(newStringReader(RawResponse)); Find a node and read its value xr.ReadToFollowing("Item"); stringplayerNodeText = xr.Value; stringplayerNameAttribute = xr.GetAttribute("Name");

  17. LINQ • LINQ = Language INtegratedQuery • Allows query expressions to benefit from compile-time syntax checking, static typing & Intellisense • Works on any IEnumerable<T>-based source • Supports querying of in-memory data sources Return all players with more than twenty home runs, sorted varfilteredPlayers = from p in players wherep.HomeRuns > 20 orderbyp.HomeRunsdescending select p;

  18. Data Binding Data Template: Data (.NET Object): {{FileName=“Html.html”, FileImageUrl=“html.jpg”}, {FileName=“Image.jpg”, FileImageUrl=“jpg.jpg”}} Bind using ItemsControl (List Control):

  19. Silverlight Sandbox • Silverlight lives in the browser Sandbox • Developers cannot extend the sandbox • Silverlight extends in a secure way • Local storage (isolated storage) • Cookies on roids • 1 MB • Extendable by user initiation • FileOpen dialog …

  20. Access the HTML DOM from Managed Code HTML access available in new namespace usingSystem.Windows.Browser; Static HtmlPage class provides entry point HtmlPage.Navigate("http://www.microsoft.com"); String server = HtmlPage.DocumentUri.Host; Hookup events, call methods, or access properties HtmlElementmyButton = HtmlPage.Document.GetElementByID("myButtonID"); myButton.AttachEvent("onclick", new EventHandler(this.myButtonClicked)); privatevoidmyButtonClicked(object sender, EventArgs e) { ... }

  21. Access Managed Code from JavaScript Mark a property, method or event as [Scriptable] [Scriptable] publicvoidSearch(stringName) { ... } Register a scriptable object WebApplication.Current.RegisterScriptableObject ("EntryPoint", this); Access the managed object from script var control = document.getElementById("SilverlightControl"); control.Content.EntryPoint.Search(input.value);

  22. Deep Zoom • Provides seamless viewing & zooming of huge images • Loads only the data necessary to show the part of an image the user is viewing • Effectively turns a large image into an efficiently scaling vector

  23. Silverlight 2 <Demo />

  24. Hot off the press H.264 support GPU Hardware Acceleration 3D 3

  25. The Reach IE8

  26. Internet Explorer 8 Standards Interoperability Improvements • CSS 2.1, HTML 4.01, HTML 5 DOM Storage, etc. • Multiple rendering modes support, Acid2 test passes! New Features • Accelerators (The artist formerly known as Activities) • WebSlices • Visual Search • Favorites bar • AJAX Improvements • Automatic crash recovery • Security Features Platform Enhancements • Performance improvements • Developer tools

  27. Versioning and IE Modes Compatibility Modes • IE8 Standard (default) – CSS 2.1-compliant • IE7 Emulation – backward compatibility with IE7 • IE5 Compatible – IE5 rendering behavior Mode Switches (Opt-in) • HTTP header: X-UA-Compatible: IE=7 • For example, Web.Config in IIS7: <httpProtocol> <customHeaders> <clear /> <add name="X-UA-Compatible" value="IE=7" /> </customHeaders> </httpProtocol> • JavaScript: document.documentMode • Meta tag: <meta http-equiv="X-UA-Compatible" content="IE=7">

  28. Compatibility View

  29. Accelerators Contextual Menu Options • Based on content selection • “look up” & “send to” external services • In-place content preview Implementation • OpenService Activity XML descriptor http://www.microsoft.com/schemas/openservicedescription/1.0 • HTTP GET/POST • JavaScript integration window.external.AddService() & IsServiceInstalled()

  30. OpenService Format <?xml version="1.0" encoding="utf-8" ?> <os:openServiceDescriptionxmlns:os="http://www.microsoft.com/schemas/openservicedescription/1.0"> <os:homepageUrl>http://maps.live.com</os:homepageUrl> <os:display> <os:name>Map with Live Maps</os:name> <os:icon>http://maps.live.com/favicon.ico</os:icon> </os:display> <os:activity category="Map"> <os:activityAction context="selection"> <os:execute method="get“ action="http://maps.live.com/default.aspx?where1={selection}" /> <os:preview method="get" action="http://maps.live.com/geotager.aspx"> <os:parameter name="b" value="{selection}" /> <os:parameter name="clean" value="true" /> <os:parameter name="w" value="320" /> <os:parameter name="h" value="240" /> <os:parameter name="format" value="full" /> </os:preview> </os:activityAction> </os:activity> </os:openServiceDescription>

  31. Web Slices Page Content Subscription • RSS-based subscriptions to portions of a Web page • Favorites Bar with update notification • Content-hover discovery • In-place content preview Implementation • Enabled by adding HTML annotations • hAtomMicroformat and Web Slice format • Refresh interval configurable Sample HTML Annotations …

  32. Add Web Slice delicategeniusblog.com <div id="dg_recent_comments"> <abbr></abbr> <?php if (function_exists('get_recent_comments')) { ?> <li><h2 class="entry-title"><?php _e('Recent Comments:'); ?></h2> <ul><?phpget_recent_comments(); ?></ul> </li> <?php } ?> </div> • <div class="hslice" id="dg_recent_comments"> • <abbrclass="ttl" title="60"></abbr> • <?php if (function_exists('get_recent_comments')) { ?> • <liclass="entry-content"><h2 class="entry-title"><?php _e('Recent Comments:'); ?></h2> • <ul><?phpget_recent_comments(); ?></ul> • </li> • <?php } ?> • </div>

  33. Web Slice Format • hAtomMicroformat describes a feed & items • Web Slice builds on hAtom • hAtom can represent static content • Web Slice is dynamic content • Web Slice reuses properties on hAtom • Adds optional properties for subscribing • ttl – time-to-live value • feedurl – alternative path to get updates • endtime – When the feed item is no longer relevant • Can be applied to an hAtom

  34. Developer Tools Built-In Developer Tools • Dynamic toggling of rendering modes • 3 modes – HTML, CSS, JavaScript HTML & CSS Explorer • Exposes internal representation of DOM tree and CSS styles • Real-time editing and rendering • Element-based style explorer • CSS file-based view in CSS mode
