Writing Custom HtmlHelpers for MVC3 and MVC4 Beta, should I use HtmlString or MvcHtmlString?

I'm writing some custom Html Helpers for my MVC3 and soon MVC4 project. Examples on the net usually show that it's done with MvcHtmlString, however, I read that if we are using .NET 4, we should be using HtmlString.

What should I use and why?

Thanks.

Always use the highest possible interface/class in the hierarchy when designing something. In this case it's IHtmlString and you could use it in ASP.NET MVC 3 and 4. 

public IHtmlString Foo(this HtmlHelper helper)
{
    return new HtmlString("foo bar");
}

Be careful when returning an IHtmlString instance from your helper. This means that it is up to you to properly HTML encode it:
