RouteCollection'不包含定义'MapMvcAttributeRoutes [英] RouteCollection' doesn't contain a definition for 'MapMvcAttributeRoutes

问题描述

我不得不降级我的 ASP.Net 4.5.2 应用程序的 ASP.Net 4.0。当然，这给它带来了问题，比如未安装引用正确。我解决了其中的一些了，但我不能让我的头周围的错误：

CS106'RouteCollection不包含
定义的MapMvcAttributeRoutes'，没有扩展方法
MapMvcAttributeRoutes接受式的第一个参数
RouteCollection'可以找到

 公共类RouteConfig 
 {
公共静态无效的RegisterRoutes（RouteCollection路线）{
 routes.IgnoreRoute（{}资源个.axd / {*} PATHINFO）; 
 
 routes.MapMvcAttributeRoutes（）; 
 
 routes.MapRoute（
产品名称：默认，
网址：{控制器} / {行动} / {ID}，
默认：新{控制器=设备，行动=查看，ID = UrlParameter.Optional}）; 
} 
} 
  

是否有人知道我要在这里做什么？

额外信息

这是我使用的命名空间：

• 使用的System.Web


• 使用System.Web.Mvc


• 使用System.Web.Routing


• 使用System.Web.Http

解决方案

支持路由属性（它提供了对 MapMvcAttributeRoutes 扩展方法的支持）MVC的唯一版本的 MVC 5 。

然而，的 MVC 5的只有的支持.NET框架4.5 和更高

所以，你有两个选择：

1. 留在.NET框架4.5 +


2. 降级到MVC 4，要么：
   
   
   
   
   1. 沟属性完全路由，并采用了约定的路由
   
   
   2. 与开源转到< A HREF =https://www.nuget.org/packages/AttributeRouting/相对=nofollow>属性的路由支持MVC 3和4
   
   
   < / LI>
   

作为微软的的官方不再支持的任何版本.NET框架低于4.5.2 （除了3.5，但是这意味着降级到MVC 2的支持），我会强烈建议你认真考虑的第一选择。

I just had to downgrade my ASP.Net 4.5.2 application to ASP.Net 4.0. Of course this brings problems with it, like references that are not installed correct. I solved some of them already, but I can't get my head around an error:

CS106 'RouteCollection' does not contain a definition for 'MapMvcAttributeRoutes' and no extension method 'MapMvcAttributeRoutes' accepting a first argument of type 'RouteCollection' could be found

public class RouteConfig
    {
        public static void RegisterRoutes(RouteCollection routes) {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapMvcAttributeRoutes();

            routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "device", action = "view", id = UrlParameter.Optional });
        }
    }

Does someone know what I have to do here?

解决方案

The only version of MVC that supports attribute routing (which provides support for the MapMvcAttributeRoutes extension method) is MVC 5.

However, MVC 5 only supports .NET framework 4.5 and higher.

So, you have 2 options:

1. Stay on .NET Framework 4.5+
2. Downgrade to MVC 4 and either:
   1. Ditch attribute routing altogether and use convention-based routing
   2. Go with the open source attribute routing that supported MVC 3 and 4

Being that Microsoft officially no longer supports any version of .NET Framework lower than 4.5.2 (except for 3.5, but that would mean downgrading to MVC 2 for support), I would highly recommend you consider the first option seriously.
