MVC 4 @Scripts＆QUOT;不存在＆QUOT; [英] MVC 4 @Scripts "does not exist"

问题描述

我刚刚创建了一个ASP.NET MVC 4项目和使用的Visual Studio 2012 RC创建一个控制器和视图剃刀索引和创建操作。

I have just created an ASP.NET MVC 4 project and used Visual Studio 2012 RC to create a Controller and Razor Views for Index and Create Actions.

当我来到运行应用程序，并浏览到创建视图，显示出以下错误：

When I came to run the application, and browsed to the Create view, the following error was shown:

编译器错误信息：CS0103：名称'脚本'不存在中
  当前上下文

Compiler Error Message: CS0103: The name 'Scripts' does not exist in the current context

问题是这是自动添加到视图底部以下code：

The problem is the following code which was added automatically to the bottom of the View:

Line 32: 
Line 33: @section Scripts {
Line 34:     @Scripts.Render("~/bundles/jqueryval")
Line 35: }

为什么脚本不存在？

Why does Scripts not exist?

我看着在大会System.Web.Mvc.dll程序，V4.0.0.0

I looked at the base Web Page class in Assembly System.Web.Mvc.dll, v4.0.0.0

我可以看到下面的助手可用属性：

I can see the following helper properties available:

• 阿贾克斯


• HTML


• 网址

但没有命名的脚本。

任何想法？

编辑：

我的web.config文件看起来像这样（从Visual Studio中创建的不变）：

My Web.config file looks like this (untouched from the one that Visual Studio created):

  <system.web.webPages.razor>
    <host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
    <pages pageBaseType="System.Web.Mvc.WebViewPage">
      <namespaces>
        <add namespace="System.Web.Mvc" />
        <add namespace="System.Web.Mvc.Ajax" />
        <add namespace="System.Web.Mvc.Html" />
        <add namespace="System.Web.Routing" />
      </namespaces>
    </pages>
  </system.web.webPages.razor>

编辑＃2：

人们在博客有关使用@Scripts助手：

People are blogging about using the @Scripts helper:

然而，刚刚安装了Visual Studio 2012 RC到全新的Windows 8安装我仍然无法使用@Scripts尽管Visual Studio中把它添加到生成的视图！

Yet having just installed Visual Studio 2012 RC onto a fresh Windows 8 install I am still unable to use @Scripts even though Visual Studio adds it to the generated View!

解决方案都低于psented $ P $。

我不知道如何关闭这一点，因为最终的更新似乎解决该问题。我仔细检查了我已经完成一个干净的安装，采用了新的项目。但是，我做了同样的失败项目的各种更新，无需人工干预明显现在后工作正常。感谢所有的想法，但也肯定是当时的一个问题;）

I am not sure how to close this, because in the end an update seemed to resolve the issue. I double checked I had performed a clean install, using a new project. But the same failing project I had made works fine now after various updates and no manual obvious intervention. Thanks for all of the thoughts but there was definitely an issue at the time ;)

推荐答案

这里的关键是要添加

 <add namespace="System.Web.Optimization" /> 

要BOTH web.config文件中。我的情况是，我不得不在这两个项目System.Web.Optimization参考，主/根web.config但@Scripts仍然没有正常工作。您需要添加命名空间参考意见web.config文件，使其工作。

to BOTH web.config files. My scenario was that I had System.Web.Optimization reference in both project and the main/root web.config but @Scripts still didn't work properly. You need to add the namespace reference to the Views web.config file to make it work.

更新：

由于MVC 4 System.Web.Optimization的发布现在已经过时。如果你开始一个空白的解决方案，您将需要安装以下的NuGet包：

Since the release of MVC 4 System.Web.Optimization is now obsolete. If you're starting with a blank solution you will need to install the following nuget package:

Install-Package Microsoft.AspNet.Web.Optimization

您仍然需要参考System.Web.Optimization在你的web.config文件。欲了解更多信息，请参阅本主题：

You will still need to reference System.Web.Optimization in your web.config files. For more information see this topic:
