RazorEngine - Namespace import compilation error

I'm using the Razor Engine (razorengine.codeplex.com) in a non-MVC environment. I compile templates that are stored in files and use @inherits for intellisense support.

RazorEngine Assembly
Custom Assembly - references RazorEngine, contains View<> and sets View<> as baseclass
Web application - references RazorEngine, Custom Assembly, contains .cshtml template files

All cshtml files have the following @inherits directive:

@inherits View<SomeModel>

An error is thrown:

The type of namespace View isn't found, are you missing an assembly reference?

My web.config contains the following entry:

<add namespace="CustomAssembly.NamespaceContainingViewClass" />

I think this has something to do with the other entry <assemblies>, where my CustomAssembly isn't mentioned. Is this the case? Can I compile with my custom base class which is contained in another assembly?

p.s. I cannot retrieve a strong name for the assembly because my custom assembly references a 3d party assembly which isn't strongly named either...

Solution

You probably need to add the razor config section to your web.config:

<?xml version="1.0" encoding="UTF-8" ?>
<configuration>
    <configSections>
        <section name="razorEngine" type="RazorEngine.Configuration.RazorEngineConfigurationSection, RazorEngine" requirePermission="false" />
    </configSections>
</configuration>

<razorEngine>
    <namespaces>
        <add namespace="CustomAssembly.NamespaceContainingViewClass" />
    </namespaces>
</razorEngine>
