Hello,
It seams that there is an issue when using MultiAppSettings with NetCoreAppSettings.
NetCoreAppSettings is working like expected but when wrapped inside MultiAppSettings, this will return always null or throw an exception.
The problem we have is with the Get<T>(string name) and Get<T>(string name, T deafultValue) methods
Thanks,
Alex.
I’m not able to repro this, if the key exists I get the configured value with both Get APIs whether it’s the first provider in MultiAppSettings or last. If it doesn’t exist it returns the expected “DEFAULT”.
AppSettings = new MultiAppSettings(
AppSettings,
new DictionarySettings());
var existsGetOrDefault = AppSettings.Get("Exists", "DEFAULT");
var existsGet = AppSettings.Get<string>("Exists");
var notExists = AppSettings.Get("NotExists", "DEFAULT");
