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:

Server Error in '/' Application

Given is the ASPX file with this content:
debopweb02:/srv/_default/htdocs # cat index.aspx
<%@ Page %>
<html><body>TEST
<p>.NET Version=<%= System.Environment.Version.ToString %>
<p>Now=<%= Now %>
<p>IP Remote User=<%= Request.ServerVariables("REMOTE_ADDR") %></body></html>

The same executed with C# works; here is the content:

debopweb02:/srv/_default/htdocs # cat index.cs.aspx
<%@ Page Language="C#" %>
<html><body>TEST
<p>.NET Version=<%= System.Environment.Version.ToString() %>
<p>Now=<%= System.DateTime.Now.ToString() %>
<p>IP Remote User=<%= Request.ServerVariables["REMOTE_ADDR"] %>
</body></html>

Both, C# and VB.NET fail 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
