[Mono-list] ASP.Net compilation error with C# and Mono V2.4.2

Thu Jul 2 06:37:28 EDT 2009

Hello,

I've got this error when trying to access my test website and if I've put a file "cammWM.dll" into my bin directory:

Given is the ASPX file with this content:

debopweb02:/srv/_default/htdocs # cat hello_world_csharp.aspx
<%@ Page Language="C#" %>
<%@ Register TagPrefix="camm" TagName="WebManager" Src="/system/cammWebManager.ascx" %>
<camm:WebManager id="cammWebManager" SecurityObject="@@Public" runat="server"></camm:WebManager>
<html>
<body>
<%
Response.Write ("<h1>This is a C# demo</h1>");
%>
<h3><asp:Label runat="server" id="UserWelcome" /></h3>
</body>
</html>
<script runat="server">
void Page_Load()
{
	UserWelcome.Text = "And you are " + cammWebManager.CurrentUserInfo().FullName() + "; a warm welcome to you!";
}
</script>

C# fails if I use a control on my page provided by that cammWM.dll. Here the message from my hello_world_csharp.aspx:

Server Error in '/' Application
