The path of the user.config files is structured as follows:

<Profile Directory>\<Company Name>\<App Name>_<Evidence Type>_<Evidence Hash>\<Version>\user.config

Where:

<Profile Directory> - is either the roaming profile directory or the local one. Settings are stored by default in the local user.config file. To store a setting in the roaming user.config file, you need to mark the setting with the SettingsManageabilityAttribute with SettingsManageability set to Roaming.

<Company Name> - is typically the string specified by the AssemblyCompanyAttribute (with the caveat that the string is escaped and truncated as necessary, and if not specified on the assembly, we have a fallback procedure).

<App Name> - is typically the string specified by the AssemblyProductAttribute (same caveats as for company name).

<Evidence Type> and <Evidence Hash> - information derived from the app domain evidence to provide proper app domain and assembly isolation.

<Version> - typically the version specified in the AssemblyVersionAttribute. This is required to isolate different versions of the app deployed side by side.

Note: The file name is always simply 'user.config'
