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

[Devin Venable]

When I don't inherit, I get this compile warning:

TestService.asmx.cs(54,54): Warning CS0114:
`MyService.MyService.EnrollTransmitter(GTPServices.WidgetEnrollmentRequest)'
hides inherited member
`MyService.MyServiceGenerated.EnrollTransmitter(TestService.WidgetEnrollmentRequest)'.
To make the current member override that implementation, add the override
keyword. Otherwise add the new keyword (CS0114) (TestSOAP2)

Should I use the new keyword?
