Silverlight Spy allows you to investigate Silverlight application. Just enter the URL in the address bar and Silverlight Spy will automatically pick up all embedded Silverlight applications. The XAP is displayed in an explorer type tree view.

Some of the features:

1. View contents of the XAP.

2. View isolated storage that is used by the application.

3. View the styles of each control. This is great as you can cut and paste the style of any control.

4. Integration with Red Gate's Reflector (formerly Lutz's Reflector) provides the disassembled code in the XAP.

5. Built-in browser.

6. Event, HTTP, and performance monitoring while the application is running.

I'm impressed and I've only used it for a few hours now.

Guess the movie

He tasks me. He tasks me, and I shall have him!
