Default The given assembly name or codebase was invalid.

I'm trying to use a compiled custom server control.

I followed instructions found on MSDN:

1. add a reference to the dll into bin folder
2. put the @register directive in a web form
3. put the <uc:webgrid ... > directive into the web form to call the control

Here is the code:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="prova.aspx.cs" Inherits="prova" %>
<%@ Register TagPrefix="uc" Namespace="Inva.WebControls2" Assembly="bin/InvaWebControls2" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title>
<form id="form1" runat="server">
<uc:webgrid id="wg1" runat="server"></uc:webgrid>

I got the error listed inthe title at IDE time and I cannto get rid of it despite many trials.

The given assembly name or codebase was invalid. (Exception from HRESULT: 0x80131047)

I also tried to recompile the source and use the fresh generated dll without success.

Please give me a hint!

Thanks a lot.
