POCannot generate database from model: System.EntryPointNotFoundException

Body
copied!<p>I've got a weird error when trying to generate database from an EF model. I've been able to reproduce this in a simple scenario. I create a new project, a new Entity Data Model, a new Entity with just the <code>Id</code> as the Key. Then I select <code>Generate Database from Model</code>, choose my DB, click Next... and then I get the following error:</p> <pre><code>Encountered the following errors while processing the template '...\DBGen\SSDLToSQL10.tt': Line 0, Column 0: 'Running transformations: System.EntryPointNotFoundException: Entry point was not found. at System.Collections.Generic.ICollection`1.get_Count() ... </code></pre> <p><img src="https://i.stack.imgur.com/ukwzF.png" alt="Generate DB Error"></p> <p><img src="https://i.stack.imgur.com/0fERg.png" alt="Generate DB Error closeup"></p> <p>The template file is present at the location referenced in the error message.<br> Tested against both <strong>MS SQL Server Express</strong> as well as <strong>2008 R2</strong>.<br> I am pretty sure I used the <code>Generate Database from Model</code> feature before and it worked fine, but I am not sure how long ago exactly (at least half a year). I got this error message with <strong>EF 4.1</strong> installed. Now I updated to version <strong>4.2</strong> and am still getting the same problem.<br> I am using <strong>Visual Studio 2010 with SP1</strong> installed (Version 10.0.40219.1 SP1Rel). Anyone seen anything like this before? Any ideas what's wrong and how to fix this?</p>
