ThreadAbortException when using Trace

[Christoph Wienands]

Hey guys,

I just got some really weird behavior. I put the following code into the
Application_Start event in Global.asax:

// init some trace listeners
Uri codeBase = new Uri(Assembly.GetExecutingAssembly().CodeBase);
string fileName = Path.GetDirectoryName(codeBase.LocalPath);
fileName = Path.Combine(fileName, "pmatsiemens_trace" +
DateTime.Now.ToString("yyyyMMddHHmmss") + ".log");
TextWriterTraceListener listener = new TextWriterTraceListener(fileName,
"FileLogger");
Trace.Listeners.Add(listener);
Trace.AutoFlush = true;
Trace.WriteLine("Application started");

When I then run a web application I notice that Application_Start is
executed over and over again. In the output window I see the following error
messages:

Application started
'/LM/W3SVC/1/Root/MyWebApp-34-127730118577453952': Loaded

Application ended
An unhandled exception of type 'System.Threading.ThreadAbortException'
occurred in Unknown Module.
Additional information: Thread was being aborted.
The program '[2760] aspnet_wp.exe:

(0x0).
The thread '<No Name>' (0x62c) has exited with code 0 (0x0).

Does anybody have a clue why this is happening?

Thanks, Christoph

Christopher,

This is only a guess, but normally in .NET when you change the web.config
file and re-save or change a .dll file and re-save the application restarts
to get the new code. Whatever listner triggers the application restart might
be triggered by your code that is writing to the application's directory.
Try saving elswhere. I think that will resolve the issue.

The ThreadAbortException is a bit of a trick ASP.NET uses when a Response.Redirect
is used.

Goood catch! Should have thought of that myself. Whenever a file changes in
the bin directory the app seems to restart. Now I just save it to a log
directory.
