"Function.createDelegate" causes "Error: Object doesn't support property or method 'createDelegate'"
<p>I am trying to get browser back button support in silverlight by following <a href="http://jakkaj.wordpress.com/2008/09/08/control-silverlight-by-using-browser-back-and-foward-buttons/" rel="nofollow">this</a> tutorial.
I am using Silverlight 4, Asp and .net4.0.</p>

<p>I am not very used to javascript and compared to C# I never really liked working with it.</p>

<p>The error message I am reciving is this: "Error: Object doesn't support property or method 'createDelegate'"</p>

<p>on this line</p>

<pre class="lang-js prettyprint-override"><code>//Create a delegate to preserve scope when the navigation event handler fires.
var handler = Function.createDelegate(historyInstance, historyInstance.navigationEventHandler);
</code></pre>

<p>My first guess is that some reference is missing but when searching I found nothing!</p>

<p>What is the cause of this error message?
Please look at the tutorial for full source code.</p>
