ASP.NET MVC3 Partial View naming convention

It’s not necessary to use an underscore, but it’s a common convention for files which aren’t meant to be served directly.

To solve this, you do have the option of returning a View or PartialView with the name of the view as a parameter.

return View("_List");

or

return PartialView("_List");

or inside another view

@{ Html.RenderPartial("_List"); }
