Hi Every one!

I started building Mvc Music Store Project in MVC4. I reached Chapter 4:"Data Access". When I pressed F5, the following Error was displayed:

Server Error in '/' Application.

Configuration Error

Parser Error Message: Sections must only appear once per config file. See the help topic <location> for exceptions.

Source Error:

Line 78:   <connectionStrings>

Line 79:     <add name="MusicStoreEntities"

Line 80:     connectionString="Data Source=|DataDirectory|MvcMusicStore.sdf"

Source File: C:\Users\munim\Documents\Visual Studio 2010\Projects\MvcMusicStore\MvcMusicStore\web.config Line: 78
