21. demo
desktop integration for all applications
and out-of-browser applications

22. trusted applications
Silverlight 4 introduces the trusted application
only for out of browser applications
indicated by metadata setting in the XAP’s manifest
• different installation experience
– can be verified or unverified ( no auto update )
• can be blocked by group policy settings

23. different types of Silverlight 4 apps
• relaxed sandbox for trusted applications
– no network restrictions on ports and x-domain/x-scheme access
– operations which require user initiation or consent relaxed
– open access to files in my [documents/videos/pictures/music]
– ability to access full file paths from file open/save dialogs
– access to the keyboard in full screen mode
– window options – alter chrome and offer alternate move/resize

24. COM interoperability
• trusted applications can call to COM code
– IDispatch interface only
– must be registered with a ProgId IDispatch
• programmability is via late binding must have a
– dynamic in C#
– no IntelliSense or compile time checking progId
• no deployment mechanism COM
– for existing code rather than new code Object
• COM is Windows only

28. WCF Data Services
RESTful service stack implementing the
Open Data Protocol ( www.odata.org )
Silverlight client stack improvements
cross-domain access to a data service
automatic change tracking of client-side entities

29. the Managed Extensibility Framework
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
Codeplex source for Silverlight 3 & .NET 3.5 Sp1

30. essence of MEF extensible set of catalogs which
discover & describe availablee.g. ISpellChecker
components
e.g. ISpellChecker
component catalog
import MEF export
Composition component catalog
component Engine
component
...
search for export(s)
e.g. WordProcessor that matches import component catalog
e.g. SuperSpellChecker

31. essence of MEF
MEF’s engine can monitor its catalogs
and update this relationship based on additions over run-time
import export
component component
e.g. another ISpellChecker shows up in a catalog?

32. one application of MEF in Silverlight
