ASP.NET MVC找不到我的名称空间

Question

I'm developing a simple blog system and I'm stuck on a position. I want to refer an external library Components, where I have Article class. Trying to set the type of the model in the view @model Components.Article I', receiving an error telling me that I'm missing some assembly (I've already refer it in References). Tried to use @using Components before the module - same result - CS0246: The type or namespace name 'Components' could not be found (are you missing a using directive or an assembly reference?) Any ideas how can I fix that?

Open the web.config file in your Views folder, and make sure it has the following:

<system.web.webPages.razor>
        <host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
        <pages pageBaseType="System.Web.Mvc.WebViewPage">
            <namespaces>
                <add namespace="System.Web.Mvc" />
                <add namespace="System.Web.Mvc.Ajax" />
<add namespace="Your.Namespace.Components" />
            </namespaces>
        </pages>
    </system.web.webPages.razor>

当您向解决方案中添加文件夹并想通过@using引用它时，有时您需要再次构建解决方案，以使该错误消失，换句话说，您需要刷新解决方案文件夹。
