visual-studio - 无法在 App_data 中添加 .mdf 文件

Question

你好

   I am not able to add .mdf file in App_data(vs 2008 web developer).
   If i right click on App_data and try to add new item and select sql server 
   file and click OK.
   I am getting error as

     "Connections to Sql Server files(*.mdf) require SQL Server Express
   2005 to function properly.Please verify the installation of the component
   or download from the url:http://www.microsoft.com/Sqlserver/2005/"

  But i have installed SQL Server Express 2005 still it is giving the same
  error(i have installed sql server after installing vs 2008)

请帮我

IIRC, you need to configure SQL Server to 'Allow User Instances'.
