Question

So I’m developing an in-house library for MVC 3 and I want to add it to my project.

I added it to my web.config. I added the assembly and added it to the pages -> namespaces section and… no. Doesn’t work.

I tried recompiling, etc… but Razor doesn’t like it at all. It’s not an intellisense problem… the site can’t run if I use my defined namespace.

The only way that I made it work was by using the following statements:

@using Sample.Helpers

I don’t want to use it in the pages. I want to be able to deploy it to many projects and adding it to the web.config is definitely the way to go.

Anyone ran into this problem?

You need to add it in the ~/Views/web.config because Razor uses a different config section:

<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="YourNamespaceContainingTheHelperMethod" />
        </namespaces>
    </pages>
</system.web.webPages.razor>
