        }

            if (env.IsDevelopment())

                app.UseDeveloperExceptionPage();
            }

            app.UseFileServer();

            app.UseMvc(ConfigureRoutes);

            app.Run(async (context) =>
            {
                await context.Response.WriteAsync("Hello World!");
            });
        }

        private void ConfigureRoutes(IRouteBuilder routeBuilder)
        {
            routeBuilder.MapRoute("Default", "{controller=Home}/{action=Index}/{id?}");
        }
    }
}

推荐答案

解决方案:使用AddMvc()代替Startup.cs中的AddMvcCore()，它将起作用.

Solution: Use AddMvc() instead of AddMvcCore() in Startup.cs and it will work.

请查看此问题以获取有关原因的更多信息:

Please see this issue for further information about why:

对于大多数用户来说，没有任何变化，您应该继续使用 在您的启动代码中添加AddMvc()和UseMvc(...).

For most users there will be no change, and you should continue to use AddMvc() and UseMvc(...) in your startup code.

为了真正勇敢，现在有了配置体验，您可以 可以从最小的MVC管道开始，并添加功能以获取 定制的框架.

For the truly brave, there's now a configuration experience where you can start with a minimal MVC pipeline and add features to get a customized framework.

您可能还需要添加参考 到project.json

You might also have to add a reference toMicrosoft.AspNetCore.Mvc.ViewFeature in project.json
