Question

我已经在这个项目上工作了很长一段时间。但现在它在我添加身份后崩溃了。错误如下：

The configuration section 'entityFramework' cannot be read because it is missing a section declaration

我认为这是一些IIS错误，因为这就是网页所说的内容。

我的web.config文件：

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

我希望有人可以帮我解决这个问题..提前致谢！

您错过了一个部分，因为错误显示：

<?xml version="1.0" encoding="utf-8"?> 
<configuration> 
<configSections> 
<!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 --> 
<section name="entityFramework" 
   type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=4.3.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" /> 
</configSections> 
 </configuration>

配置部分＆lt; entityFramework＆＃39;无法读取，因为它缺少一个部分声明
