I had the need to display a button that works like an action link to redirect the user to a page within an Area and didn’t want to wrap the whole thing in a form just to do the redirect. Here is what I used. It allows the same styling and behavior as a button but redirects directly like an action link.
<input type="Submit" value="Add Persona" class="btn btn-primary btn-lg" onclick="location.href='@Url.Action("Detail", "Persona", new { area = "ProfileInfo" })'" />
