    <p>Now, I promise that I've googled this. Stack overflow has about 4 or 5 solutions to this issue. Still, none of them seem to be working. I'm using EntityFramework 5 (4.4) with an MVC 3 project. This has worked fine in the past, but it's been a while since I've opened the project (about 20 days or so). I've just uninstalled &amp; reinstalled Sql Server 2008 R2 Express. I've rebooted since then.</p> <p>In all of my cshtml files I see an error underlineline on my @model line. When I mouse over it, I see the following: </p> <p>ASP.NET runtime error: Could not load file or assembly 'EntityFramework, Version=4.4.0.0, Culture=neutral, PublicTokenKey=b77a5c561934e089' or one of its dependencies. Access is denied.</p> <p>I have uninstalled and re-installed the EntityFramework package via package manager console. I've done it via nuget as well. I've closed and re-opened visual studio. I've removed the reference and added it manually via browsing for the dll.</p> <p>My web.config entry for this looks like: </p> <blockquote> <p>[open tag]section name="entityFramework" type="System.Data.Entity, EntityFramework, Version=4.4.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" [close tag]</p> </blockquote> <p>Any one have any thoughts?</p> <p><strong>EDIT 1 FULL ERROR DETAIL</strong></p> <pre><code>Server Error in '/' Application.

I'm still getting the error.</p> <p>As I was still getting Access Denied for errors, I gave Users full control of the folder on my machine. The application loads. So...this is a permission error. The question is, what account needs the permissions?</p>

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).
