The type or namespace name 'function' could not be found?
<p>I am writing a function proc in my C# 2008 ASP.Net application and I get the following error:</p>

<blockquote>
  <p>The type or namespace name 'function'
  could not be found (are you missing a
  using directive or an assembly
  reference) ?</p>
</blockquote>

<p>Any idea what this means?</p>
