BC30560: 'default_aspx' is ambiguous in the namespace 'ASP'

Question

When I compiled my latest asp.net program and trying to run on the test server, I am getting this error

Line 46:             Dim dependencies() As String
Line 47:             CType(Me,Global.System.Web.UI.Page).AppRelativeVirtualPath = "~/default.aspx"
Line 48:             If (Global.ASP.default_aspx.__initialized = false) Then
Line 49:                 dependencies = New String(0) {}
Line 50:                 dependencies(0) = "~/default.aspx"

Detailed errors when I expand the compiler output...

I checked a few things and all of them turned out to be okay:

[*] Default is not defined twice anywhere

[*] Everything was working on the last release 1 week back

[*] There are no old files that are still staying with the compiled files. Also I cleared the temporary files many times.

[*] I have tried with other aspx files and all of them is giving ambiguous error (error in different source files...)

[*] The original source works just fine! only the error shows up on the compiled code.

Any ideas or any clues on how to resolve this ambiguity.

Thanks SK

I just solved this problem with the assistance following link: http://www.netomatix.com/development/usercontrols2.aspx

Add this on aspx or ascx page ClassName="MyModule"

   <%@ Control Language="vb" AutoEventWireup="false" CodeBehind="MyModule.ascx.vb" ClassName="MyModule" %>
