The ApplicationSettingsBase.Reset method overwrites the user-scoped settings properties by restoring the currently persisted value of each application settings. This method performs the following actions:
It calls the IApplicationSettingsProvider.Reset(SettingsContext) method on every settings provider that supports this optional method.
It calls the ApplicationSettingsBase.Reload method to force a refresh of the settings property values.
ApplicationSettingsBase.Reload contrasts with ApplicationSettingsBase.Reset in that the former will load the last set of saved application settings values, whereas the latter will load the saved default values.
