xmlserializer - source files not generated using diagnostics swit

[Steven.Dahlin]

In the app.config one can set it so the xmlserializer does not delete the
source files for the serialization classes using the following:

<configuratio n>
<system.diagnos tics>
<switches>
<add name="XmlSerial ization.Compila tion" value="4" />
</switches>
</system.diagnost ics>
</configuration>

However, I am not finding the source files being generated. Is there
something I am not doing corretly?

Thanks,
Steve
