Neue Datei appsettings.json im root-Verzeichnis erstellen

In z.B. Program.cs:

public static IConfiguration _conf;
var configuration = new ConfigurationBuilder()
  .AddJsonFile($"appsettings.json");
_conf = configuration.Build();

Connection String auslesen:

string connectionString = _conf.GetConnectionString("DefaultConnection")!;

Setting auslesen:

string s = _conf.GetSection("section").Value!;

Verschachtelte Settings auslesen:

"MainSection": {
  "SubSection": {
    "SubSubSection": "value"
}
string s2 = _conf.GetSection("section:SubSection:SubSubSection").Value!;
