HTML5MVCInputTags (nuget): A number of extensions to the existing HtmlHelper class, which allow a developer to directly generate HTML 5 input tags tied to a models value. Also includes additional metadata functionality to define placeholder text, validation patterns and min, max and step values.  N.B. For the date-orientated controls Min, Max and Step are currently disabled due to the unobtrusive javascript validation expecting numeric values. I'm currently looking into a workaround for this in order to allow them to be used in date-based inputs.
