Generating Client Code

Of course, you shouldn’t have to build HTTP or SOAP requests by hand. And indeed, you don’t; the .NET Framework SDK includes a tool, wsdl.exe, which can generate web service client code from any WSDL file.

Run the command line wsdl /language:vb http://127.0.0.1/dotNetAndXml/InventoryQuery.asmx?WSDL to produce the Visual Basic .NET source code listed in Example 10-7 for the InventoryQuery service.
