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

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
