title: Failure attaching SQL Server 2008 database to SQL Server 2005
body: <p>I developed an application in ASP.net 4.0 in visual studio 2010, connected with a SQL Server 2008 database. I copied my ASP.net application to a webserver IIS 6.0 with a SQL Server 2005 EXPRESS, OS Windows 2003 werver.
  When I try to browse my website I get the following error:</p>
  <blockquote>
  <p>The database 'C:\TELEFOON\TELEFOON\APP_DATA\ASPNETDB.MDF' cannot be opened because it is version 655. This server supports version 611 and earlier. A downgrade path is not supported.</p>
  <p>Could not open new database 'C:\TELEFOON\TELEFOON\APP_DATA\ASPNETDB.MDF'. CREATE DATABASE is aborted.
  An attempt to attach an auto-named database for file C:\Telefoon\Telefoon\App_Data\aspnetdb.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.</p>
  </blockquote>
  <p>I do understand the problem but is there a solution?</p>
