Typically, an application doesn't write to its config file. You'll find

Hi:

I've the same problem, if i modify the App.config manually it will
reset back to original each time the application run, if i exclude the
App.config in my solution, the app.config will deleted each time the
application run.

What am i doing wrong ?

Thanks

And if you are lucky enough to run VS2005 you can use the application
settings designer and/pr the Client Config API to load/save settings.
