CreateDefaultBuilder方法都做了什么?

当我们创建好一个新的ASP.NET Core Web应用时,系统会使用CreateDefaultBuilder方法,这个方法完成了以下操作:

  • use Kestrel as the web server and configure it using the application's configuration providers
  • set the ContentRootPath to the result of GetCurrentDirectory()
  • load IConfiguration from 'appsettings.json' and 'appsettings.[EnvironmentName].json'
  • load IConfiguration from User Secrets when EnvironmentName is 'Development' using the entry assembly,
  • load IConfiguration from environment variables
  • configure the ILoggerFactory to log to the console and debug output
  • and enable IIS integration

如果使用了CreateDefaultBuilder的有参数版本,则还会通过命令行参数来初始化IConfiguration。
