• different installation experience – can be verified or unverified ( no auto update )
• can be blocked by group policy settings
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
COM interoperability
COM Object
IDispatch
must have a progId
• trusted applications can call to COM code – IDispatch interface only
– must be registered with a ProgId
• programmability is via late binding – dynamic in C#
– no IntelliSense or compile time checking
• no deployment mechanism – for existing code rather than new code
• COM is Windows only
