You'd fix that by including jQuery!

Add the following to your page

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>

However, it sounds like just an error in Visual Studio, and if it works when viewing the page in a browser, it shouldn't be an issue.

or any other script that provides $ as global variable.

@AdamMoszczyński - The question is tagged jQuery, so I assumed the $ was jQuery. Could be a number of other things, scripts overwriting $, noConflict mode, as in Wordpress etc.

@HassanAliKhan - Then it's not loading, or you're not including before you're trying to use it, or $ is overwritten by something else. Is this just in VS2010, or in the browser as well.

@HassanAliKhan: Check that you have that Scripts/jquery.qtip-1.0.0-rc3.min.js on the server

@HassanAliKhan:- If your script is in a Scripts directory then you just use Scripts/jquery.qtip-1.0.0-rc3.min.js because with a web server, everything is within it's root (top level) directory.

First verify that jQuery is in fact being loaded.

if (window.jQuery) {  
  alert("jQuery is loaded!");
}

If that works, then you are most likely using something like jQuery.noconflict() to remove the alias $ for jQuery.
