First of all I would like to apologize because I have found many topics with similar problem but none solved mine.
I have developed a ASP.net website (C#) in Visual Studio 2012 Ultimate. I created the App_Data folder and created a SQL Sever Database. When all the development was done, I decided to deploy the website to IIS7 on Windows Server 2008 R2. After deployment, most of the webpages work just fine, except the ones with data from the database.
I have selected the .Net FrameWork version in IIS to v4.0
This is the error I am getting when accessing the pages with a gridview for example.
