Can't add LINQ to ASP.NET web page
<p>I've got a simple ASP.NET website, but I can't get it to work. The server is running IIS 7.5 with .NET 4.0 installed, and I've got complete access, and I'm using VS2010 to generate an ASP.NET 4 website. But VS automatically generates code-behind files with <code>using System.Linq;</code> in them. This wouldn't be a problem for me except it doesn't seem to reference Linq by default. I added in the IIS Manager/site/.NET Compilation/Assemblies list the System.Data.Linq assembly, <em>and</em> I added a reference to it in the web config, but it's still complaining that <code>System.Linq</code> does not exist.</p>

<p>The website works fine on my home machine where I'm developing it with VS2010 installed.</p>

<p>What's the problem?</p>
