asp.net-mvc – Visual Studio无法解析模型,但加载了Razor页面

导读：我有一个MVC 5应用程序,由空模板制作.我通过Nuget添加了Microsoft.AspNet.Mvc,我的包文件如下所示： packages package id="Microsoft.AspNet.Mvc" version="5.2.3" targetFramework="net46" / package id="Microsoft.AspNet.Razor" version="3.2.3" targetFr

我有一个MVC 5应用程序,由空模板制作.我通过Nuget添加了Microsoft.AspNet.Mvc,我的包文件如下所示：

<packages>
  <package id="Microsoft.AspNet.Mvc" version="5.2.3" targetFramework="net46" />
  <package id="Microsoft.AspNet.Razor" version="3.2.3" targetFramework="net46" />
  <package id="Microsoft.AspNet.WebPages" version="3.2.3" targetFramework="net46" />
  <package id="Microsoft.CodeDom.Providers.DotNetCompilerPlatform" version="1.0.0" targetFramework="net46" />
  <package id="Microsoft.Net.Compilers" version="1.0.0" targetFramework="net46" developmentDependency="true" />
  <package id="Microsoft.Web.Infrastructure" version="1.0.0.0" targetFramework="net46" />
</packages>

我有一个Razor页面,用@model IEnumerable< Models.ToDoModel>声明了一个模型.并在foreach循环中使用它.

@model IEnumerable<Models.ToDoModel>

<!DOCTYPE html>

    <html>
    <head>
        <meta name="viewport" content="width=device-width" />
        <title>Home</title>
    </head>
    <body>
    <h1>Hello World!</h1>
    <ul>
        @foreach (var item in Model)
        {
            <li>ID: @item.Id</li>
        }
    </ul>
    </body>
</html>

当我运行页面时,它呈现正常,但Visual Studio坚持说有一个错误：

它不会识别模型关键字或给我任何智能感知.

我的Web.Config看起来像这样：

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

和Views文件夹中的Web.Config如下所示：

<?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,PublicKeyToken=31BF3856AD364E35">

      <section name="pages" type="System.Web.WebPages.Razor.Configuration.RazorPagesSection,PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
    </sectionGroup>
  </configSections>

  <system.web.webPages.razor>
    <host factoryType="System.Web.Mvc.MvcWebRazorHostFactory,System.Web.Mvc,Version=5.2.3.0,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>

  <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>

解决方法

你的web.configs看起来都很好. Visual Studio经常会对此类事情感到困惑.我的建议是关闭Visual Studio并重新打开它.此外,正如您所发现的,可能需要关闭VS的所有打开实例.
