Abp框架下 Area中新建Layout报错的问题

ABP框架下，新建Admin的Area。

在Area中定义底层Layout报错，原因为@ApplicationPath无法解析：

<script type="text/javascript">
        //This is used to get the application's root path from javascript. It's useful if you're running application in a virtual directory under IIS.
        var abp = abp || {}; abp.appPath =  '@ApplicationPath';
    </script>

　　解决方法：

修改Admin下的WebConfig文件为：

<?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=5.2.3.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
    <pages pageBaseType="WebMonitor.Web.Views.WebMonitorWebViewPageBase">
      <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="WebMonitor.Web" />
      </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>

　　主要是为了设置pageBaseType属性为：WebMonitor.Web.Views.WebMonitorWebViewPageBase，

View继承了此类后即可解析：@ApplicationPath
