Xamarin not found
<p>I've been having issues with compiling code. The code was running successfully, and I uploaded it to Team Foundation Server. However, when people (including myself) downloaded the code from Team Foundation Server, the code produced the error:</p>

<p>"Error  CS0246  The type or namespace name 'Xamarin' could not be found (are you missing a using directive or an assembly reference?)"</p>

<p>I've got the newest version of Xamarin.Forms.</p>

<p>Code:</p>

<pre><code>using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using Xamarin.Forms;

namespace XamlSamples
{
        public class App : Application
    {
        public App()
        {
            // The root page of your application
            MainPage = new HelloXamlPage();
        }        
            };
        }
</code></pre>
