Applications, resources, and deployment

1. Week 4 – Applications, Resources, and Deployment Jim LaVine jim.lavine @gmail.com

2. Agenda Loading the application XAP files Binary resources Xaml resources Application class Application extensions

3. Loading the Plugin HTML <object> tag Compiled Silverlight content Splash / download UI Error Handling Fallback content

4. Code Behind <object id=“slPlugin” width=“100%” height=“100% type=“application/x-silverlight-2” data=“data:application/x-silverlight-2,”> <paramname=“source” value=“client/bin/SLContent.xap” /> <paramname=“onerror”value=“onSilverlightError” /> <paramname=“minRuntimeVersion”value=“4.0.50401 .0” /> <paramname=“autoUpgrade”value=“true” /> <ahref=“http:go.microsoft.com/fwlink/?linkid=115261” style=“text-decoration: none;> <imgsrc=“http:go.microsoft.com/fwlink/?linkid=108181” alt=“Get Microsoft Silverlight” style=“border-style: none”/> </a> </object>

5. Silverlight.js Benefits Silverlight.IsInstalled helper Can choose content at runtime Disadvantages More Complex Extra file to download Moving Target

6. Using Silverlight.js <script type="text/javascript" src="Silverlight.js"></script> … <divid=“slPLaceholder”></div> … <script type="text/javascript"> Silverlight.createObject( "ClientBin/SLObject.xap", document.getElementById("slPlaceholder"), "slControl", {width:"500" heigth:"500", version:'4.0'}, {onError: myErrorHandler} );</script>

7. XAP Just a Zip Main DLL Dependent DLLs Resources Mainfest Server config Mime type for .xap:application/x-silverlight-app

8. AppManifest.Xaml <Deployment xmlns=http://schemas.microsoft.com/client/2007/deployment xmlns:x=“http://schemas.microsoft.com/winfx/2006/xaml” EntryPointAssembly=“UriStyles” EntryPointType=“UriStyles.App” RuntimeVersion=“4.0.50401.0”> <Deployment.Parts> <AssemplyPartxname=“UriStyles” Source=“UriStyles.dll”/> <AssemplyPartxname=“Systems.Windows.Controls.Data” Source=“Systems.Windows.Controls.Data.dll”/> </Deployment.Parts> </Deployment>

9. Application Library Caching Package shared assemblies separately Exploit browser caching <Deployment xmlns=http://schemas.microsoft.com/client/2007/deployment xmlns:x=“http://schemas.microsoft.com/winfx/2006/xaml” EntryPointAssembly=“UriStyles” EntryPointType=“UriStyles.App” RuntimeVersion=“4.0.50401.0”> <Deployment.Parts> <AssemplyPartxname=“UriStyles” Source=“UriStyles.dll”/> </Deployment.Parts> <Deployment.ExternalParts> <ExtensionPartSource=“Systems.Windows.Controls.Data.zip”/> </Deployment.ExternalParts> </Deployment>

10. Resources: XAP vs ‘Loose’ Images, Media, etc. in Silverlight projects end up in XAP: Application is self contained Availability guaranteed once application starts Can add to Web site instead Faster startup Easier to change

11. Resources and URIs Image ad MediaElement refer to resources Absolute ‘pack:’ URI not supported URI Style Location Img.jpg In Xap (falls back to site, relative to .xap location) /Img.jpg In DLL as embedded resource (alsofalls back to site) /AssemblyName;component/Img.jpg In Xap (falls back to site, relative to .xap location) http://example.com/app/Img.jpg Specified Location

12. Download UI Define as Xaml Set SplashScreenSource <param> Optionally handle onSourceDownloadProgressChanged V1 programming model - JavaScript
