Razor-based view doesn't see referenced assemblies
I'm attempting to create a strongly-typed view based on a class from another assembly. For whatever reason though, my Razor view doesn't seem to have any visibility of other assemblies referenced on my project. e.g.
@model MyClasses.MyModel
results in the error in Visual Studio 2010, "The type or namespace name MyClasses could not be found (are you missing a using directive or an assembly reference?)."
The same class referenced in the standard view engine works fine. I have the same trouble trying to reference the class in the body of my view.
Am I missing something about Razor or do I need to reference the assembly some other way?

There is a new configuration section that is used to reference namespaces for Razor views.
Open the web.config file in your Views folder, and make sure it has the following:
<configuration>
<configSections>
<sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
<section name="host" type="System.Web.WebPages.Razor.Configuration.HostSection, System.Web.WebPages.Razor, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
<section name="pages" type="System.Web.WebPages.Razor.Configuration.RazorPagesSection, System.Web.WebPages.Razor, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
</sectionGroup>
</configSections>
<system.web.webPages.razor>
<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<pages pageBaseType="System.Web.Mvc.WebViewPage">
<namespaces>
<add namespace="System.Web.Mvc" />
<add namespace="System.Web.Mvc.Ajax" />
<add namespace="System.Web.Mvc.Html" />
<add namespace="System.Web.Routing" />
<add namespace="SquishIt.Framework" />
<add namespace="Your.Namespace.Etc" />
</namespaces>
</pages>
</system.web.webPages.razor>
</configuration>
Alternatively, you can add using statements to your shared layout:
@using Your.Namespace.Etc;
<!DOCTYPE html>
<head>
....
After editing the Web.config, restart Visual Studio to apply the changes.
