What does Silverligtht 4.0 Trusted Mode mean on a Mac?

Question

Are there any special considerations we will need to take into account for Mac scenarios? Furthermore, with features such as COM interop which aren't applicable on a Mac, how do you give visibility of these capabilities to your code?

if (Silverlight.Environment.SupportsCOMInterop) {
   // do stuff
}

More generally, could your code determine whether it's running on a Mac or Windows?

Answer 1

Shawn Wildermuth gave a talk last night in Atlanta and he discussed some of the potential compatability issues with the Elevated Trust (not Full Trust) on the Mac. He mentioned that Drag-and-Drop support is going to be difficult because of the way Safari/Firefox (can't remember which one) is used to run out-of-browser on the mac. HTML embedding on the Mac might also be an issue. Shawn is speaking at notatpdc.com tonight about SL4 features. You might want to attend and ask: http://www.notatpdc.com/Schedule/Detail/20 (note, time is central time).

According to the LIVE speak afterwards (approx. 2h ago): besides the lack of COM (obviously) Trusted Mode on Mac should be equivalent to the TM on Windows (access to hardware/cam/keyboard/file-system).
