WCF proxy class generation WSDL VS SVCUTIL

Svcutil and wsdl are two different technologies for generating a proxy for consuming your service. But wsdl.exe was made for old .NET 2.0 web services. It is like old version of svcutil. Svcutil allows you to generate proxies for both - web services and WCF services. For generating a proxy wsdl retieves the data by means of DISCO discovery protocol. Svcutil also supports DISCO. But it can make the proxy retrieval using WS-Metadata Exchange protocol, which is an interopable standart of SOA.

I advice you to use svcutil because it would allow you to consume both .net 2.0 web services and wcf services.
