svcUtil error 'SchemaLocation' must successfully resolve if <redefine> contains any child other than <annotation> [closed]

I am trying to generate a proxy from a 3rd party wsdl and xsd files. I am calling svcutil like so:

svcutil *.wsdl *.xsd /language:C#

It returns this error: 'SchemaLocation' must successfully resolve if contains any child other than .

There is only one element in all the files, and it's schemaLocation attribute points to another file in the same directory. 开发者_Go百科I tried fully qualifying the uri, but that did not help.

Ideas?

This error was caused by an unrelated problem with the wsdl file. The portType operation parameters were named, but the binding operation peramters were not. When I fixed this svcutil generated the proxy, so I assume it must have been able to find the proper xsd includes.
