Add link and script tags to include the required libraries:
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css"><script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script><script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script><script src="/Scripts/signalr-client-1.0.0-alpha2-final.min.js"> </script>
If you do not want to use bootstrap for the look and feel, you don't need the bootstrap JavaScript library or CSS, but note that we will be using jQuery in our scripts, so leave that one in.
