This may be useful to someone:

If you already got jQuery but still get this error, check you include jQuery before the js that uses it, specially if you use @RenderBody() in ASP.NET C#

You have to include jQuery before the @RenderBody() if you include the js inside the view that @RenderBody() calls.
