Error when add the StoreManagerController on MVC Music Store Tutorial Part 5

When I followed the MVC Music Store Tutorial using Microsoft Visual Studio Express 2012 for Web on Windows 8, I got this error:

Unable to retrieve metadata for 'MusicStore.Models.Album'. Using the same DbCompiledModel to create context against different types of database servers is not supported. Instead, create a separate DbCompiledModel for each type of server being used.

No idea. Let google for a solution. Here a solution from ITorian (http://www.itorian.com/2012/10/unable-to-retrieve-metadata-for.html) :

After I delete this line in web.config, it worked: 

     connectionString="Data Source=|DataDirectory|MvcMusicStore.sdf"

     providerName="System.Data.SqlServerCe.4.0"/>
