Fiddler to calculate page load time of silverlight app

I have a silverlight application that I want to calculate the page load time through C # using the Fiddler API. Could you please share some helpful suggestions on how I can do this using fiddler / fiddlercore. Here are some details of what I want to do ...

• Launch fiddler and start IE (without using httpweb request)
• Download my app url.
• Calculate page load time

Earlier I tried to use the httpwatch API to calculate it. Httpwatch does all of this, but it doesn't calculate the load time of the silverlight component.

Please, help.

Thanks, Pritam
