[Mono-aspnet-list] creating new web service from wsdl

[Devin Venable]

And with NEW I get this error:

TestService.asmx.cs(58,58): Error CS0533:
`blah.blah.EnrollTransmitter(blah.TransmitterEnrollmentRequest)' hides
inherited abstract member
`blah.blahGenerated.EnrollTransmitter(blah.WidgetEnrollmentRequest)'
(CS0533) (TestSOAP2)
