Best way to store configuration details?

So I have a windows application (C# .NET VS2008) where i put my configuration values into Settings like so...(Solution's View -> Your Project name -> Properties -> settings.Settings - which seemed like the right thing to do.  But, what i was really looking for was a way to change application settings easily without needing to recompile and without having to put controls in to the application itself to allows them to be changed (the program runs silently and so putting controls in to allow changes to config values via the application itself is not really practical).  I was expecting to see something like a app.config file (like i see when i develop a web service) get written to the installation directory of the application after i install it (or perhaps it is there - but i just don't know where to look?)

Ok, so based on those articles, it sounds like i can not actually edit a config file outside of the application to change config values.  My options would be...  1. open the project, change the "settings" and rebuild.  2. provide a form in the application to allow a user to change these values.   Please correct me if i am wrong.  What i really want to know is, how do i change application config values OUTSIDE of the application (meaning without having to build it again and without having to provide an interface of some kind).  If there is a file i can edit - if so - where is it?  I see config files all over the place - which one will actually affect these values at run time?  (Sorry newbie here - you have talk slow an simple for me)

yes you can edit the values in those files. it is a XML file so open it with Notepad and do it.

when you add settings in your file and then build and deploy your application and applicationname.exe.config file is also installed the bin folder
all your settings are part of that file and if you need to modify some setting then open the file in some editor and update the setting
you dont need to build the setup and deploy it agian if some setting changes

I figured out what was happening (now remember i said i was a newbie).  I was publishing my  application and then installing it from the setup.exe created.  This did some magical stuff that didn't produce what i had expected (which was a app.exe and an app..exe.config file).  Instead it produced some manifest files an d a file called app.exe.config.deploy.  So a friend told me to build a new "set up wizard" project and add it to my solution.  Doing this produced an msi installer, but this time, when i installed it, it made a app.exe and an app.exe.config file.  I could then opent the config xml and edit it directly as i wanted to.  I think the setup.exe created by the "publish" action is just doing some magic that i don't understand - i could not locate the config file after installing this way.
