I think I understand my problem now. I was clicking on the Start Debugging button when Configuration manager was set to Release. I guess that even when you set configuration manager to Release and press on Start Debugging, VS wants to debug but no debugging information is available. So I need to click on Start without Debugger item. If I remember correctly it worked a little differently in VS 2003.

Again, thank you for your help.
