From the docs (which in this case I wrote):

将Directory.GetCurrentDirectory指定为内容根目录时，从该文件夹中启动应用程序时(例如，从Web项目文件夹中调用dotnet运行)，它将使用Web项目的根目录文件夹作为应用程序的内容根目录.这是Visual Studio和dotnet新模板中使用的默认设置.

Specifying Directory.GetCurrentDirectory as the content root will use the web project's root folder as the app's content root when the app is started from this folder (for example, calling dotnet run from the web project folder). This is the default used in Visual Studio and dotnet new templates.

如果不添加此目录，则内容根目录将默认为应用程序根目录，该目录是程序运行所在的位置(可能在/bin文件夹中的某个位置).如果要从源/项目根目录启动Web应用程序，通常这不是您想要的.

If you don't add this, the content root will default to the application root, which is wherever the program is running from (probably somewhere in a /bin folder). This usually isn't what you want if you're launching the web app from its source/project root.
