Where is trace.write going?

Where do I get trace output?

Trace.Write("Hello World");

Hi,

ASP.NET Page will show trace outputs when you add Trace="True" to page
directive, that is:

<%@ Page Trace="True"...%>

You can also have an application level tracing, more information here:

Trace class output goes to trace listeners. You can define your own trace listeners or use the already defined in .Net.

The idea is to use the <trace> element of the application .config file.
You can decide during the
runtime of the Debug/Release (depending whether you use Debug/Trace class),
if the output is directed to any "Listener". You can even declare your own
classes as output sinks using the <listeners> element. This allows you to
send for instance the output to remote machine (TCP/IP?), WebService,
Window, etc. At your will.

Have a look at the following links:

A higher level runtime tracing tool is EIF (Enterprise Instrumentation
Framework):

Try as I may, I cannot get a trace.axd. All aspx @page has trace=true and web.config has trace=true.

My folders look like this

folder1
---default.aspx
---web.config
---folder2
-----default.aspx
-----folder3
----------mydll.dll <=== I need to see trace.write output

If your application is writing trace information (as opposed to single page
trace) you can see it by typing you path plus trace.axd. I don't think the
information is actual in a file. It may be in memory somewhere.

It's actually implemented as an http handler which recieves the request from
an axd extension. See rob howards book for a more detailed explanation if
you care.
