    <p>I am trying to follow this guide <a href="http://www.pluralsight-training.net/microsoft/players/PSODPlayer.aspx?author=scott-allen&amp;name=mvc3-building-data-i&amp;mode=live&amp;clip=0&amp;course=aspdotnet-mvc3-intro" rel="nofollow">http://www.pluralsight-training.net/microsoft/players/PSODPlayer.aspx?author=scott-allen&amp;name=mvc3-building-data-i&amp;mode=live&amp;clip=0&amp;course=aspdotnet-mvc3-intro</a> (Part 3 Code Comes first) but I have followed it like a slave.</p> <p>Now I have installed a MSDN version so its the Visual Studio Ultimate and not the Web developer express 2010 like he uses and I wonder is that the sole reason for this not working? Because then I will just install that instead.</p> <p>I get this error when I try to access a site that should use the database</p> <blockquote> <pre><code> Server Error in '/' Application.

    1. COAre you able to connect to the database in the Visual Studio Server Explorer? What connection string do you have configured in web.config? Can you paste your whole <connectionStrings> section of your web.config file?

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
