Questions tagged [appsettings]
appsettings.json (Application Settings) is a settings file. When configured, it can be used by .NET as a configuration source for settings you need at runtime & is automatically used by IIS to load all relevant web server settings. You can have multiple appsettings.json files for various environments in the format of appsettings.Environment.json e.g. appsettings.Production.json. Also used commonly to store logging settings like level & verbosity.
