How to get CPU Usage of a Silverlight application from code?

I need to build a widget which would show (and monitor) CPU usage by a Silverlight instance (the control will be part of the silverlight application and would track the running instance). I could not find Process/PerformanceMonitor class in Silverlight.

Is there any existing API or some way to do this?

Edit 1) Same question being answered fo开发者_开发技巧r non-Silverlight: How to get the CPU Usage in C#?

Thanks for your interest.

You should be about to use System.Windows.Analytics.AverageProcessorLoad to get the CPU load.

Not sure if OOB or Elevated Trust is required for this to work.
