I can't see any trace output in ASP.NET
<p>In Visual Studio 2010 I added Trace to Page_Load as explained here <a href="http://www.asp101.com/articles/robert/tracing/default.asp" rel="nofollow">http://www.asp101.com/articles/robert/tracing/default.asp</a> but I can't see any Trace output, why ?</p>

<pre><code>public partial class _Default : System.Web.UI.Page {

    protected void Page_Load(object sender, EventArgs e) {

        Trace.IsEnabled = true;
        Trace.Write("Hello World");

    }

}
</code></pre>
