ASP.NET MVC - NHaml issue on web.config file

Question

Hello There, I'm trying to implement NHaml views on my application, and it's all working well. But strangely I'm getting some warnings on web.config files when publishing the application.

My nhaml parameters are:

<configSections>
  ...
  <section name="nhaml" type="NHaml.Configuration.NHamlConfigurationSection, NHaml"/>
</configSections>
<nhaml autoRecompile="true" templateCompiler="CSharp3" encodeHtml="false" useTabs="false" indentSize="2">
  <assemblies>
    <add assembly="MyApp"/>
  </assemblies>
  <namespaces>
    <add namespace="MyApp" />
    <add namespace="MyApp.Controllers" />
  </namespaces>
</nhaml>

So, it's weird because the haml views are being rendered without any problems, but every time I open the web.config file I get the following warnings:

Message 1   Could not find schema   information for the element   'nhaml'.            C:\inetpub\MyApp\Web.config 25  4   MyApp

Am I doing something wrong?

Thank you for your attention. :)

Seems these are just VS telling you that the custom elements cannot be found inside the XSD for what it thinks configuration files should look like. The same happens with nhibernate.

So you are not doing anything wrong and u can ignore the messages. They are just informational.

Based on this blog post http://fgheysels.blogspot.com/2006/04/net-20-could-not-find-schema.html

I could create an nhaml XSD for the config (the same way the nhibernate folks have) but it is not high on my list of priorities. Feel free to have a go at it if the messages really annoy you.
