Silverlight in a Cocoa WebView in sandboxed app mode

Silverlight in a Cocoa WebView in sandboxed app mode

The problem is quite simple, I have a WebView that may be used to browse some page that may contain a silverlight app.

Everything works well in non sandboxed mode.

In sandboxed mode, all the webkit plugins work, except Silverlight: no exception thrown, nothing in the sandboxd logs, just an empty silverlight app placeholder in the page.

I was wondering if anyone stumbled upon the same issue and found a way to make it work :)

Update: I added the following key/value to my entitlements file but it did not help

<key>com.apple.security.temporary-exception.mach-lookup.global-name</key> <array>     <string>com.apple.WebKit.PluginAgent</string> </array>
