TagPrefixAttribute Question

[G Dean Blake]

I'm going through this book on asp.net server control development. I wrote
a control using the namespace:

ESS.ServerControls

The book says that if I put the following in my control's AssemblyInfo.vb
file that my controls will be prefixed by an "ess" tagPrefix:

Imports System.Web.UI
..
..
<Assembly: TagPrefix("ESS.ServerControls", "ess")>

But it does not work. When my control gets dragged onto an aspx page, a
TagPrefix of "cc1" gets generated.

Anyone know what is wrong?
Thanks
G.

I don't know if this is it, but the example from the MSDN documentation
(from VS2005 Beta 1) is:

Imports System
Imports System.Web
Imports System.Web.UI
Imports System.Web.UI.WebControls

<assembly: TagPrefix("CustomControls", "custom")> _

Namespace CustomControls

' Simple custom control
Public Class MyVB_Control
Inherits Control
Private message As String = "Hello"

Public Property getMessage() As String
Get
Return message
End Get
Set (ByVal value As String)
message = value
End Set
End Property

<System.Security.Permissions.PermissionSetAttribute(System.Security.Permissions.SecurityAction.Demand,
Name:="FullTrust")> _
Protected Overrides Sub Render(writer As HtmlTextWriter)
writer.Write(("<span style='background-color:aqua; font:8pt tahoma,
verdana;'> " + Me.getMessage + "<br>" + "VB version. The time on the server
is " + System.DateTime.Now.ToLongTimeString() + "</span>"))
End Sub 'Render
End Class 'MyControl
End Namespace 'CustomControls

The difference seems to be that those docs have me putting the TagPrefix
assembly directive in the source to the control itself instead of in the
AssemblyInfo file. I tried it and still got the same thing cc1.
