A first chance exception of type 'System.Threading.ThreadAbortException'
Am building a .net web application on my local machine and when I insert a breakpoint so I can test something I see all the messages (below) in the immediate window.
Everything is working fine with the app so I'm not sure what they can mean. There are no other messages in other windows to give me any other clues.
What is it trying to tell me?
asp.net 4.0
c#
visual studio 2010

First chance exceptions are handled by the runtime. They will not cause your application not to function.

so what is it taking exception to?

I have a couple of response.redirects that are set up to take a user back to a particular page should there be some missing querystring data... but I'm not testing that part of the app when I'm seeing this. Or will these exceptions be thrown even if that portion of the code is not running (arrived at)?

actual I'm wrong I am using a response.redirect on button click and each time I use it I get another exception so it looks as though you've nailed that one...
"A first chance exception of type 'System.Threading.ThreadAb
An exception of type 'System.Threading.ThreadAb
Not sure how to recreate this one though
"A first chance exception of type 'System.NullReferenceExcep
I went to debug->exceptions and ticked everything, but other than write to the intermediate window nothing other seems to be happening in debug mode.
Should it not break and highlight the offending line?
Should I care about these exceptions?

Not at all, this is the purpose of a "First Chance" exception.

It's likely an external piece of code is catching the NullReferenceException and handling it gracefully.
