When the Web Services Description Language (WSDL) imports a schema that includes multiple schema by using the xsd:include element and when these schemas include any command schema, the WSDL tool (Wsdl.exe) cannot generate the proxy for the Web service. For example, you have the following files:
In this example, the Top.xsd schema includes the Schema2.xsd schema and the Schema3.xsd schema, and both of these schema include the Common.xsd schema. If the Example.wsdl file imports the Top.xsd schema, proxy generation by using the Example.wsdl file fails.
