Additional Silverlight 5 new features include:

  • P/Invoke support for calling native functions – enables existing native code to be run directly from Silverlight.
  • 64 bit support
  • Remote Control and Media Command Support
  • DataContextChanged event
  • In-Browser Trusted Applications
  • PivotViewer Control
  • Power awareness for media apps

The software giant said Silverlight 5 performance improvements include: Reduced network latency by using a background thread for networking; XAML parser improvements that speed up startup and runtime performance; support for 64-bit operating systems; and reduced network latency by using a background thread for networking.

Moreover, Silverlight tools improvements include Microsoft Visual Studio profiling support including CPU, memory, thread contention and Visual Studio Team Test support.
