Add Service Reference error "Cannot import wsdl:portType"

Question

I cannot get the Add Service Reference in VS 2010 or 2012 to work for web services built on ServiceStack . I have followed the guide on github, including adding the ContractNameSpace attribute to the AssemblyInfo.cs file and ensuring all my DTOs are in the same namespace but with no luck. Instead I receive a number of build warnings error messages that I have included below.

Does anybody have any suggestions about what is going wrong?

Does disabling "Reuse types in referenced assemblies" in the Service Reference Configuration help? – Ogrady

Welcome to SO, Please use the comment section to leave question – Jackfish

I'm really struggling with this one as well, my DTO's have datacontract and datamember attribtutes on them though and I've made them really simple to try and just get it working, still crashes just like yours above – Sp

@Ozz Its best if you could create a separate question for your issue including the test code. Once you have done this I can have a look and see if I can identify the cause of your problems. – Abscess

Answer 1

I discovered the root of my problem. One of my DTOs was not decorated with [DataContract] and [DataMember] attributes.

This meant the WSDL produced by ServiceStack didn't contain the type information for this DTO, so when one of the message sub-sections of the WSDL referred to this DTO type VS couldn't find it and threw the exception.

Hopefully this will help someone else. It took me quite a bit of time to figure out what I did wrong.

Yeah this is already listed in the SOAP Support wiki page at Make sure that DTO objects have [DataContract] attribute... – Templeton

Answer 2

Another reason could be :Check targetNamespace could have created conflict, remove any instance of tempuri.org - put consistent namespace appropriately, would resolve above error.

targetNamespace='http://tempuri.org/']/wsdl:portType[@name='IMyInterafaceService' 

Hope it helps

There is nothing inherently wrong with using tempuri.org, as long as it is used consistently. – Doctrine
