iis - 如何修复不会编译简单应用程序的 IIS Express？

Question

如果我创建一个新的空 MVC 应用程序，添加一个 Controller 和一个 View ，然后运行我会收到一个编译错误，该错误似乎来自 IISExpress，因为它在 Visual Studio 中没有显示为错误。

Server Error in '/' Application.

Compilation Error

Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: BC30451: 'ViewData' is not declared. It may be inaccessible due to its protection level.

Source Error:

Line 1:  @Code 
Line 2:      ViewData("Title") = "Index" 
Line 3:  End Code 

Views web.config 似乎是正确的，因为它包含各种必需的命名空间:

<?xml version="1.0"?>

<configuration>
  <configSections>
    <sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
      <section name="host" type="System.Web.WebPages.Razor.Configuration.HostSection, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
      <section name="pages" type="System.Web.WebPages.Razor.Configuration.RazorPagesSection, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
    </sectionGroup>
  </configSections>

  <system.web.webPages.razor>
    <host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=5.1.0.0, 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" />
        <add namespace="MVCAjaxWorkbench" />
      </namespaces>
    </pages>
  </system.web.webPages.razor>

  <appSettings>
    <add key="webpages:Enabled" value="false" />
  </appSettings>

  <system.webServer>
    <handlers>
      <remove name="BlockViewHandler"/>
      <add name="BlockViewHandler" path="*" verb="*" preCondition="integratedMode" type="System.Web.HttpNotFoundHandler" />
    </handlers>
  </system.webServer>
</configuration>

而且主要的 web.config 似乎也是正确的:

<?xml version="1.0" encoding="utf-8"?>

我认为我安装的 IISExpress 出了点问题。我已经查看了使用 IIS instead of IISExpress 的选项我真的更愿意坚持使用 IISExpress，但只是重新安装它没有任何区别。我的下一步是尝试重新安装 Visual Studio，但我宁愿尽可能避免这样做，因为它本身往往会产生副作用。

如何修复我的 IISExpress 安装，使其在 Visual Studio 中正常运行？

Answer 1

实际上，我通过执行以下操作成功地完成了这项工作:

• 卸载 IISExpress
• 运行 Visual Studio 2013 的“修复”安装
• 清理解决方案并在 System.Web.MVC (following some of the answers in this question) 的引用属性中设置 Copy Local = True
• 使用包管理器对话框更新所有 MS 和 .NET DLL
• 更新 JQuery 和 Bootstrap(仅作为更新 DLLS 的结果)

虽然我怀疑它正在设置 Copy Local = True 但我无法确定其中哪一个是关键步骤，但 MS 更新 appears to be the source of the problem .
