I added a few methods to the Web Service, it stills build without any error but when I try to initiate the WSDL file, I have:

Compiler Error Message: BC30560: 'Global' is ambiguous in the namespace 'WebService'.

Source Error:

Line 31:     <System.Runtime.CompilerServices.CompilerGlobalScopeAttribute()>  _
Line 32:     Public Class Global_asax
Line 33:         Inherits WebService.Global
Line 34:         
Line 35:         Private Shared __initialized As Boolean = false

Anyone has any idea where I should fix what? The problem is at line 33. This is the line shown in red.
