this is weird. I see references out there for @Html.Button() but when I type that Intellisense doesn\'t find such a helper... there\'s dropdownlist, hidden, editors, et cet
Razor does not appear to have a "Button" HTML helper. You're likely finding references to a custom-built HTML helper extension.
