In some of the previews, there was an HTML-helper method for building mailto-links.

I am not able to find that in the final release. Am I missing something?
I know they removed some of those HTMLHelpers from the final version. That might be one of them. Previews are generally notorious for changes. You might want to look at the MvcFutures project.
