WSDL.exe and VB.NET Case insensitive / Duplicate name

Hi,
When I used the tool WSDL.exe and i take VB.NET language, I have a little problem with duplicate name.
I've got the error ID:BC30663  Attribute 'GeneratedCodeAttribute' cannot be applied multiple times.
MSDN suggest to add Attribute Usage with the option AllowMultiple at true, but the error still here.

Any suggestion?

Here a part of the generated code...

Partial Public Class GetAccountInformationResponse
    Private getAccountInformationResponseField As GetAccountInformationResponse
...
End Class
