✅ What is the best way to setup app configuration using IHostBuilder?

I want to make a good building of my host configuration and make it convenient to use. My goal is to get the as much as possible:
- Convenience;
- Strongly typing;
- Won't compile against typos in keys;

I've already tried those ways to setup configuration and found them inconvenient:
1.

HostBuilderContext.Configuration["Key"]

HostBuilderContext.Configuration["Key"]

· hardcoding keys;
2.

context.Configuration.Get<Configuration>()

context.Configuration.Get<Configuration>()

· calling the same method everywhere;
3.

context.Configuration.Bind(configuration)

context.Configuration.Bind(configuration)

· confusing where to bind it at the first time;

Personally I'm using the third way, because it saves me from code duplication and hardcoding keys, but also brings a new problem — confusing where to bind the configuration.

Currently, I'm binding it in the

IHostBuilder.ConfigureAppConfiguration

IHostBuilder.ConfigureAppConfiguration

internal class Program
{
    private static readonly Configuration _configuration = new();

    private static async Task Main(string[] args)
    {
        var host = Host.CreateDefaultBuilder(args)
            .ConfigureAppConfiguration(b => b.Build().Bind(_configuration))
            .ConfigureServices((context, services) =>
            {
                services.AddSingleton(_configuration);
            })
            .Build();

        await host.RunAsync();
    }
}

internal class Program
{
    private static readonly Configuration _configuration = new();

    private static async Task Main(string[] args)
    {
        var host = Host.CreateDefaultBuilder(args)
            .ConfigureAppConfiguration(b => b.Build().Bind(_configuration))
            .ConfigureServices((context, services) =>
            {
                services.AddSingleton(_configuration);
            })
            .Build();

        await host.RunAsync();
    }
}

Ideally, I would like to redefine

content.Configuration

content.Configuration

so that its type matches

Configuration

Configuration

(my custom class), in order to directly get values without hardcoding, for example:

context.Configuration.Token

context.Configuration.Token

. But I understand that this may not be possible.
