It is known that Microsoft.AspNetCore package is one of the packages added to
many ASP.NET Core templates.
The Microsoft.AspNetCore package is repeatedly included as one of the usual project
在打开一个新的ASP.NET Core项目时,它提供了许多依赖项
关键的软件包以设置一个基本的ASP.NET Core应用程序。
尽管如此,该软件包不包含任何实际的dll或代码,它仅包含
a series of dependencies on additional packages. By adding this package to your
project, you bring in all the relevant packages along with their dlls on which it
depends and it is called a metapackage.
Specifically, the packages it lists are −
Microsoft.AspNetCore.Diagnostics
Microsoft.AspNetCore.Hosting
Microsoft.AspNetCore.Routing
Microsoft.AspNetCore.Server.IISIntegration
Microsoft.AspNetCore.Server.Kestrel
Microsoft.Extensions.Configuration.EnvironmentVariables
Microsoft.Extensions.Configuration.FileExtensions
Microsoft.Extensions.Configuration.Json
Microsoft.Extensions.Logging
Microsoft.Extensions.Logging.Console
Microsoft.Extensions.Options.ConfigurationExtensions
NETStandard.Library
The versions of these packages you will receive depends on which version of the Microsoft.AspNetCore package you install.
These dependencies deliver the primary basic libraries for setting up a basic
ASP.NET Core服务器使用Kestrel Web服务器,并包含IIS集成。
就应用程序本身而言,仅使用此软件包,您可以加载
将应用程序设置和环境变量转换为配置,请使用IOptions
interface,并配置日志输出到控制台。
对于中间件,只包括 Microsoft.AspNetCore.Diagnostics 包
这将允许添加中间件,如ExceptionHandlerMiddleware,the
开发者异常页面中间件(DeveloperExceptionPageMiddleware)和状态码页面中间件(StatusCodePagesMiddleware)。
为了完成一个应用程序,我们不能仅仅使用元包(Metapackage),因为它不
提供足够的控制,但我们可以使用 Microsoft.AspNetCore.Mvc 或
Microsoft.AspNetCore.MvcCore package to add MVC capabilities to our application,
and also some other packages would be needed.
The metapackage just try to use a number of packages that can be applied to many
应用程序,这样我们就不需要加载更多的依赖项,但实际上并没有这样做
that because it requires
