Asp.net mvc Ext.NET未与ASP.NET MVC 4集成

我在VS2012中创建了一个MVC4Web应用程序。 通过NuGet下载了Ext.NET2。 在我的view/home/index.cshtml文件中，我试图键入：

@Html.X().ResourceManager()

当我跑步时，我得到以下信息：

CS1061:'System.Web.Mvc.HtmlHelper'不包含'X'的定义，并且找不到接受'System.Web.Mvc.HtmlHelper'类型的第一个参数的扩展方法'X'（是否缺少using指令或程序集引用？）

这是我的web.config

您能否确认在项目中添加了对Ext.Net.dll的正确引用

编辑：我认为

中的

节点不正确。应如下所示，其中每个部件定义为单独的

我相信NuGet可能有缺陷。我们已经看到了NuGet将这些程序集配置添加到上的其他报告

如果您对

进行上述更改，您的项目应该可以正常工作

请不要使用Nuget获取Ext.Net dll。我相信Ext.Net团队不会尽快在Nuget中更新Ext.Net dll。因为我发现版本是Nuget是2.1.1.11828，它没有Ext.Net.Mvc命名空间。但是最新发布的版本是2.1.1.18233，它有Ext.Net.Mvc命名空间…

是的，我相信我添加了正确的引用。直接从NuGetSomething获取的Ext.Net 2项目设置中缺少或配置错误。也许下面的线程可以帮助您，请参阅也许还应该添加下面的Web.config，请参阅我在上面添加了我的Web.config。请帮忙！最新版本的Ext.Net中不再存在命名空间Ext.Net.MVC。
