You are not alone who finds this too over engineering :)

Anyway this is more related to C# and Mvc idioms and so much about EPiServer. In this particular case Func<TArg,TResult> is a function this may be passed in as argument to MenuList method. This function represents "some code block" that may be called later while generating menu.

In AlloyTech Func<> is actually generated by view engine - in this case Razor. In this case you are declare this helper method inline while calling to MenuList method. Is it more clear if you look at following code?

@helper RenderItem(HtmlHelpers.MenuItem item)
{
    <li class="@(item.Selected ? "active" : null)">
        @Html.PageLink(item.Page, null, new { @class = string.Join(" ", item.Page.GetThemeCssClassNames()) })
    </li>
}

and then:

@Html.MenuList(ContentReference.StartPage, RenderItem)

Thank you Valdis!

You made it some what more clear but i still feel quite confused. :)

I'm not the person to say if this code is over engineerd or not but i think it's hard to understand and i need to practise more!

I found this link if there is any one else out there also confused: http://vibrantcode.com/blog/2010/8/2/inside-razor-part-3-templates.html

Please feel free to post links that explains this way of programming :)
