Asp.net core ASP.Net核心MVC项目无法配置路由？

我最近开始学习ASP.NETCore来开发MVCWebAPI。但我甚至无法运行我的hello world

在

Startup.cs

中，我写道：

public void ConfigureServices(IServiceCollection services)
{
    services.AddRouting();
    services.AddMvc(routes =>
    {
        routes.MapRoute(
            "default",
            "{version?}/{controller=Home}/{action=Index}/{id?}");
    });
} 

控制台上说：

error CS1929: 'MvcOptions' does not contain a definition for 'MapRoute' and the best extension method overload 'MapRouteRouteBuilderExtensions.MapRoute(IRouteBuilder, string, string)' requires a receiver of type 'IRouteBuilder'

您必须添加

配置

方法而不是

配置服务

。试试这个样品

这里将mvc添加到服务中

 public void ConfigureServices(IServiceCollection services)
    {

        services.AddMvc();

    }

这里设置路线

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
        {

            app.UseMvc(routes =>
            {
                routes.MapRoute(
                    name: "default",
                    template: "{controller=Home}/{action=Index}/{id?}");
            });
        }
