Well, today I had something very annoying. I was working on my Silverlight application for the customer I’m working for and suddenly, when I hit F5 in my Visual Studio, debugging didn’t work anymore. I had no idea what was going on, did a rebuild of the solution after a clean, but nothing helped.
There was however a simple way to fix it. Just go to the properties page of the web project hosting the application and remove the application.
Then add the application again (remove the check before “Add a test page that references the control” or you’ll get another test page) and fire it up again.
This fixed it for me. Hope this also helps somebody else. Let it know if it was helpful.
