Deployment/References

[Dave]

I created a deployment project for a small web app using
VS.net. It works fine on my development machine but on
the deployment machine I get

System.MissingMethodException: Method not found:
System.Collections.Specialized.NameValueCollection
System.Web.HttpRequest.get_QueryString().

Stack Trace:

[MissingMethodException: Method not found:
System.Collections.Specialized.NameValueCollection
System.Web.HttpRequest.get_QueryString().]
Nanuuk.GUI.Freedom.BindGrid() +0
Nanuuk.GUI.Freedom.Page_Load(Object sender, EventArgs e)
System.Web.UI.Control.OnLoad(EventArgs e) +67
System.Web.UI.Control.LoadRecursive() +29
System.Web.UI.Page.ProcessRequestMain() +724

I haven't been able to decode this. There is a reference
to "System.Dll" in the project so a call to
System.Collection ought to be OK, no? In "BindGrid" there
is a Request.QueryString:

If Not Request.QueryString("Page") Is Nothing Then
CurPage=Convert.ToInt32(Request.QueryString("Page" ))
Else
CurPage=1
End If

I can't figure out why this error is thrown. Any Ideas?

Thanks...
