我的webconfig文件有问题:

Question

   <compilation debug="false" targetFramework="4.0">

当该行为红色时,我收到此错误:

Parser Error Message: Sections must only appear once per config file.  See the help topic <location> for exceptions.

我以为我也在机器配置文件中重复一些东西,然后我去搜索配置属性并发现:

                <section name="compilation" type="System.Web.Configuration.CompilationSection, System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=****" requirePermission="false"/>

我试图删除它,它会导致问题,所以我再次把它.

是什么导致了这个错误？

你的web.config中有两个编译标签:

<sessionState mode="SQLServer" sqlConnectionString="SqlState" allowCustomSqlDatabase="true" cookieless="false" timeout="20"/>
<compilation debug="true"/>

和你最初发布的那个.
