我在VS 2010 express上创建了一个新的mvc4项目。现在我想向db添加角色。我使用包管理器控制台运行update-database命令来插入角色,它给我以下错误

PM> Update-Database -verbose

尚未启用“角色管理器”功能。

我需要启用角色管理器,但我找不到web.config中的部分

以下是web.config文件

默认情况下该部分不存在,但您可以添加它。

将其放在<system.web>

e.g。

<system.web>
   <roleManager defaultProvider="CustomRoleProvider" >
     <providers>
       <clear />
       <add name="CustomRoleProvider" type="MyNamespace.CustomRoleProvider" />
     </providers>
   </roleManager>
   <compilation debug="true" targetFramework="4.0" />
....
