how to determine the last time a user input was received in silverlight 3

Question

I have a Silverlight 3 application, and in a method, I want to determine when the last time that the application received user input was. Is there an easy way to detect this?

Thanks for any help.

I doubt there is framework support for such a value, but you should be able to roll your own easily enough by monitoring key, mouse and other input events and setting a timestamp value accordingly. You could even persist this in isolated storage to carry the value across sessions (provided the user has not disabled isolated storage of course).
