✅ How to Get DI Services in a Console Application

var builder = Host.CreateApplicationBuilder(args);

builder.Configuration.Sources.Clear();
IHostEnvironment env = builder.Environment;
builder.Configuration
    .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
    .AddJsonFile($"appsettings.{env.EnvironmentName}.json", true, true);

builder.Services.Configure<DbOptions>(builder.Configuration.GetSection("Database"));
builder.Services.AddTransient<EnvironmentService>();

using var serviceProvider = builder.Services.BuildServiceProvider();

var svc = serviceProvider.GetService<EnvironmentService>();
svc.ImportEnvironment(@"C:\Development\WorkProjects\Postman\Environments\seriti-V3-local-small.postman_environment.json");
