Extend MVC Html Helpers to return if an evaluation returns true. Example: @Html.ActionLink("Test Link", "SomeAction", "SomeController").If(Roles.GetRolesForUser().Contains("Admin"))

HtmlHelpersIfExtension.cs

namespace System.Web.Mvc 
{
  public static class HelperExtensions 
  {
    public static MvcHtmlString If(this MvcHtmlString value, bool evaluation)
    {
      return evaluation ? value : MvcHtmlString.Empty;
    }
  }
}

This is pretty cool!
