Debugging a first chance exception in MSCORLIB.DLL

Hi, I have a fully working application, but I noticed that I get different
exceptions while running in debug in the output window:

 

A first chance exception of type 'System.Threading.ThreadAbortException'
occurred in mscorlib.dll

 I am using visual studio 2005.


Now the application still runs after these exceptions are thrown, and I read in
many places online that I could go to the exceptions window, then check the box
to break on my exception right?  Which I did, but this doesn't stop the
exceptions in mscorlib.dll.  I am wondering how exactly I can configure the
debugger to stop on first chance exceptions AND can stop in mscorlib.dll so I
can get a stack trace and figure out whats going on.  Thank you.

Thread Abort exceptions may be normal in an ASP.NET Application. If anywhere in
your code you use Response.Redirect("url"); or
Response.Redirect("url", false); it will cause a thread abort. This is
because the first overload or the second overload with false calls
Response.End(); which in turn calls a Thread.Abort();

This may be what you are seeing.

Kevin,

 Thank you for your response, but I am getting 4 different types of these first
chance exceptions at varying times.
  I really need to know how I can get visual studio to break at these
exceptions, when I configure it in the exceptions tab to break, it doesn't
break.  Thanks, I am using VS 2005, ASP .NET 2.0.

in mscorlib.dll

System.Web.dll

mscorlib.dll
