When I've deployed a Windows Forms application, how can I change the default settings?

问题

I've deployed a Windows Forms application. On my local development PC, there is a settings.settings file which contains all the app's settings.

I'm aware as-per this question and others like it, that a User.config file gets created in c:\Users\username\Local Settings\AppData\Local\...

However, I need to change a default setting, so that when users start it for the first time, the default settings are different than when we initially deployed the app.

So the first time a user runs the app, it creates their local copy of the file.

What does it base that on? Is there a default copy of the file somewhere, or is it compiled into the .exe?

I need to get the default settings updated on an app that's deployed on several laptops remotely where I only have telephone support. If I have to recompile and republish then that needs to be as a last resort.

Considering this facts may be useful:

• The default values for user settings are stored in yourapplication.exe.config beside yourapplication.exe
• Current values for user settings are not in this file and any change in them could be saved using Properties.Default.Settings.Save()
• If there is no yourapplication.exe.config in your executable folder, it will be created automatically using values in your .settings file.
• If you call Properties.Default.Settings.Reset() the values in yourapplication.exe.config will be used to override user saved values.
• Adding a new settings requires recompile and republish.
• To overcome the pain of update and distribution, you may consider ClickOnce.
