Errors using SvcUtil.exe on a wsdl to generate proxy class - xs:group element

Question

I'm trying to use SvcUtil against a wsdl file to generate proxy classes, but I'm getting an element missing error that I think is related to schema group elements. Does anyone know for a fact if svcutil can handle ? And if so will it handle xs:group elements that have ref attributes that point to the group definition that lives in another schema file?

SvcUtil.exe Command (included the paths to the xsd files as well):

d:\codegen\svcutil.exe d:\codegen\RPE\ProtocolStateManager.wsdl d:\codegen\RPE\schema\RPE.xsd d:\codegen\RPE\schema\PORT_MT100001UV.xsd d:\codegen\RPE\schema\coreschemas\infrastructureRoot.xsd d:\codegen\RPE\schema\coreschemas\dataTypes.xsd d:\codegen\RPE\schema\coreschemas\voc.xsd /l:cs

The error is:

Error: Cannot import wsdl:portType Detail: An exception was thrown while running a WSDL import extension: System.ServiceModel.Description.XmlSerializerMessageContractImporter Error: Group InfrastructureRootElements is missing.

Answer 1

I'm not sure about SvcUtil, but for XSD.exe and WSDL.exe you have to specify all the files that are used by the .xsd file, because they don't recognize elements. Maybe my post will help you, too: http://seanmcilvenna.com/blog/7-general/30-xca-implementation

Answer 2

I found this tool - WSCF Blue - from a post on msdn forums. It got me past my errors and also looks to offer quite a bit more in terms of functionality.
