The complete download should be fixed. Sorry the wrong file was there.
If you are using Trace.Write() then you are using the default source. You need to attach the listener to the source you are using. For the default (rather than a named source), use something similar to the following (note the listeners are added to <trace>,
not a specific source.... the same listener can be added to multiple sources):
<trace autoflush="true" indentsize="0" >
<add name="rollingfile" />
Note that while it will work with the default source, it is good practice to use separate sources for the major different components of your system.
Using sources provides better logging (more options), as well as allowing you to turn on/off or set the trace level differently for different components.
