Answer 1

I would write a custom action link helper:

public static class LinkExtensions
{
    public static IHtmlString ActionLinkIfInRole(
        this HtmlHelper htmlHelper, 
        string roles,
        string linkText, 
        string action
    )
    {
        if (!Roles.IsUserInRole(roles))
        {
            return MvcHtmlString.Empty;
        }
        return htmlHelper.ActionLink(linkText, action);
    }
}

and then in my views:

@Html.ActionLinkIfInRole("Administrators", "Create New", "Create")
