Value does not fall in expected range
<p>When creating simple control I am getting this error, I have no clue why this is occurring.</p>

<p>For any control it is giving same error.Please help me out from this.</p>

<p>Here is the code : </p>

<pre><code>&lt;asp:Label ID="Label1" runat="server" Text="Label"&gt;&lt;/asp:Label&gt;
</code></pre>

<p>Thanks 
Aman</p>
