I have a User Control that I created (.ascx & .ascx.vb file pair) that I am trying to put in a separate assembly. I know that the User Control works when it is in the same project and is compiled along with the project it is used in, so the problem is obviously something I am doing wrong with the references or something. My current code registers the assembly as:
<%@ Page Language="vb" AutoEventWireup="false" Codebehind="DatePickerTest.aspx.vb" Inherits="WebApplication1.DatePickerTest"%>
<%@ Register TagPrefix="NateCtrl" Namespace="NateCtrl" Assembly="NateCtrl" %>

<title>DatePickerTest</title>

<body>
<form id="Form1" method="post" runat="server">
<NateCtrl

<asp:label id="lblSelectedDate" runat="server"></asp:label>
<asp:button id="btnRefresh" runat="server" Font-Bold="True" EnableViewState="False" Text="Refresh"></asp:button><BR><BR>

<asp:button id="btnNewYear95" runat="server" Font-Bold="True" EnableViewState="False" Text="New Year's 1995" CausesValidation="False"></asp:button>
</form>
</body>
</HTML>
When I attempt to execute the page, I recieve the following error:
Server Error in '/WebApplication1' Application.

What am I missing here? Thanks.
