I have a strange error. I'm debugging an asp.net site and suddenly it stops. Visual Studio stays in debug mode and my web application stays on running just fine. I found this post on, but I don't think a background thread is causing the problem. There's even a try catch around the code where it usually stops debugging, but the catch is not triggered... Everytime I try it, it stops at a different place in the code.
Check mode in your ide its set to Debug not to Release.
Because cannot able to debug your application if it set to Release mode.

Make sure the "Ping Enabled" setting is set to "False" in the IIS configuration.
In IIS7, right-click on your AppPool, choose "Advanced Settings," navigate down to the Ping Enabled setting and change it to false.
If you're using IIS6, the setting is slightly different. I believe it's called "Ping Interval" if I remember correctly and it's set to a number of seconds.
