MS wsdl.exe: Cannot find definition for...Parameter name: name

Are you trying to generate a CS proxy for a WSDL which maybe imports another WSDL which in turn maybe imports a XML Schema and so on? (e.g. MyServiceConcrete.wsdl -> MyServiceAbstract.wsdl -> MyServiceSchema.xsd).

I come from the Java world, so the natural way for me would be:

wsdl.exe MyServiceConcrete.wsdl

But...crash

Microsoft (R) Web Services Description Language Utility

Error: Cannot find definition for ... EndpointInterface.  Service Description with namespace ... is missing.
Parameter name: name
  
If you would like more help, please type "wsdl /?".

And for example, Java's wsimport works like a charm:

wsimport.exe MyServiceConcrete.wsdl

The problem is wsdl.exe doesn't resolve import's (neither xsd.exe)

So just feed wsdl.exe with all the required dependencies (WSDLs, XSDs...).

wsimport.exe MyServiceConcrete.wsdl MyServiceAbstract.wsdl MyServiceSchema.xsd

In the above example, all files have to be in the same directory.

Profit.
