How to get Configuration from appsettings in dotnet core console application

I am using a dotnet core 7 worker project in which I want to add app settings to my program.cs class but for that I need an Iconfiguration from the host context. How can I get and inject it as a singleton in the project?

Here is my code:

IHost host = Host.CreateDefaultBuilder(args)
    .ConfigureServices(services =>
    {
    // Here I want to add a configuration from appsettings.json and then map it to my Configuration class
        services.AddHostedService<Worker>();
    })
    .Build();

host.Run();

Here are my appsettings:

{

"ServiceName":"Test service",
"connectionString":""
}

public class Configuration{
    public string ServiceName {get;set;}
    public string ConnectionString {get;set;}


}

>Solution :

You can use the Bind method to bind the Configuration segment to a static typed object instance.

https://learn.microsoft.com/en-us/aspnet/core/fundamentals/configuration/?view=aspnetcore-7.0#bind-hierarchical-configuration-data-using-the-options-pattern

Configuration.GetSection(PositionOptions.Position).Bind(positionOptions);

Or even more convenient the Get method

 Configuration.GetSection(PositionOptions.Position).Get<PositionOptions>()
