Now all Step Into and Step Over and Step Out, all are in light color and none can be pressed.Please see the screenshot on this link also on clicking "Web" i get this see the link please prntscr.com/34eya9

I am using Firefox Could that be a problem for not debugging ? But it is displaying the GUI i have created using xml and c#

Answer 1

right click on the project, go to "properties", select "web" tab, scroll at the bottom, and you will find that under "debuggers" silverlight is not checked.

check that, and rebuild the solution.

this should then enable silverlight debugging.
