内容根目录

The content root is the base path to any content used by the app, such as its views and web content. By default the content root is the same as application base path for the executable hosting the app; an alternative location can be specified with WebHostBuilder.

内容根目录是app使用的所有内容的基路径，例如app的视图和web内容。 默认情况下内容根目录就是可执行托管app的应用基路径。 可以使用 WebHostBuilder 来确定一个可选的位置。
