试图标记为ODATA时可查询属性不是MVC 4个Web API编译 [英] Queryable attribute is not compiling in mvc 4 web api when trying to mark for odata

问题描述

我使用附带的Visual Studio 2012 MVC 4个Web API。

I'm using MVC 4 web api that comes with visual studio 2012.

因为我已经明白ODATA不会自动分析，但我们需要的属性现在加上[可查询]的动作。

As I've understand odata is not parsed automatically, but we need to add [Queryable] attribute to the action now.

所以我添加它：

public class TestController : ApiController
{
    [Queryable]
    public IQueryable<MyClass> GetMyClasses()
    {
       return ...;
    }
}

但我发现了一个编译错误：

but I'm getting a compilation error:

The type or namespace name 'Queryable' could not be found (are you missing a using directive or an assembly reference?) 

时的ODATA仍然支持？为什么可查询不被识别为属性，如这里列出。

Is the odata still supported? and why Queryable is not recognized as an attribute as listed here.

感谢您

推荐答案

作为解释<一个href=\"http://blogs.msdn.com/b/alexj/archive/2012/08/15/odata-support-in-asp-net-web-api.aspx\">here, OData的支持已被移动到一个单独的的NuGet包。

As explained here, OData support has been moved to a separate NuGet package.
