/// load <see cref="IConfiguration"/> from 'appsettings.json',
/// load <see cref="IConfiguration"/> from User Secrets when <see cref="IHostingEnvironment.EnvironmentName"/> is 'Development' using the entry assembly,
/// load <see cref="IConfiguration"/> from environment variables,
/// load <see cref="IConfiguration"/> from supplied command line args,
/// configures the <see cref="ILoggerFactory"/> to log to the console and debug output,
/// and enables the ability for frameworks to bind their options to their default configuration sections.
