Answer 1

.net core

var builder = new ConfigurationBuilder()
              .AddJsonFile(@"<path to appsettings.json>");

var configuration = builder.Build();
//  configuration["TAG DESIRED"]

.net framework

 using (var reader = new StreamReader(Directory.GetCurrentDirectory() + "/appsettings.json")) {
        Settings appSettings = JsonConvert.DeserializeObject<Settings>(reader.ReadToEnd());
    }

Settings class must match your json structure

 public class Settings
    {
        .. List of props to be bound.
    }

This worked for me!

var httpDirectory = Path.Combine(new DirectoryInfo(Environment.CurrentDirectory).Parent!.Parent!.Parent!.Parent!.Parent!.FullName,
    "src",
    "ApiGateways",
    "Web.Management",
    "Web.Management.HttpAggregator",
    "bin",
    "Debug",
    "net6.0",
    "appsettings.json"
);
