.NET Core 3.1 loading config from appsettings.json for console application
23,219
In .Net Core 3.1 you need to install these packages:
-
Microsoft.Extensions.Configuration.Json
-
Microsoft.Extensions.Configuration.FileExtensions
then build IConfiguration
:
static void Main(string[] args)
{
IConfiguration configuration = new ConfigurationBuilder()
.AddJsonFile("appsettings.json", true,true)
.Build();
var playerSection = configuration.GetSection(nameof(Player));
}

For .NET Core 3.1, console application how can I read a complex object from appsetting.json file and cast it into the corresponding object?
All the examples I see online seem to be for previous versions of .NET core and things seems to have changed since then. Below is my sample code. I don't really know how to proceed from here. Thank you for your help.
appsettings.json
{ "Player": { "Name": "Messi", "Age": "31", "Hobby": "Football" } }
Player.cs
class Player { public string Name { get; set; } public string Age { get; set; } public string Hobby { get; set; } }
Program.cs
static void Main(string[] args) { var config = new ConfigurationBuilder() .SetBasePath(Path.GetDirectoryName(Assembly.GetEntryAssembly()?.Location)) .AddJsonFile("appsetting.json").Build(); var playerSection = config.GetSection("Player"); }
