A skeleton for a .NET console application with dependency injection

Here is an example of a simple console application written in .NET that demonstrates the use of dependecy injection

It shows the use of the following services:

• IConfiguration from appsettings.json
• Console logging

Include the following packages from nuget:

• Microsoft.Extensions.Configuration
• Microsoft.Extensions.Configuration.Json
• Microsoft.Extensions.Logging
• Microsoft.Extensions.Logging.Console

using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;
using System.Text;

namespace MyNamespace;

internal class Program
{
    static ServiceProvider ConfigureServices()
    {
        ServiceCollection services = new ();
        
        IConfiguration configuration = new ConfigurationBuilder()
        .SetBasePath(Directory.GetCurrentDirectory())
        .AddJsonFile("appSettings.json", false)
        .Build();


        services.AddLogging(loggerBuilder =>
        {
            loggerBuilder.ClearProviders();
            loggerBuilder.AddConsole();
        });

        services.AddSingleton<MyService>();
        services.AddSingleton(configuration);

        return services.BuildServiceProvider();
    }

    

    static async Task Main(string[] args)
    {
        ServiceProvider serviceProvider = ConfigureServices();

        ICertificateManagerClient certificateManager = serviceProvider.GetRequiredService<MyService>();
        IConfiguration configuration = serviceProvider.GetRequiredService<IConfiguration>();
        
        string myValue = configuration.GetValue<string>("MyValue");
    }
}
