Add error to service link "Unable to import wsdl: portType"

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

Does anyone have any suggestions on what is going wrong?

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

This meant that the WSDL created by ServiceStack did not contain type information for this DTO, so when one of the sections of the WSDL message related to this type of VS could not find it and threw an exception.

Hope this helps someone else. It took me a long time to understand what I did wrong.

Another reason may be the following: Check targetNamespace can create a conflict, delete any instance of tempuri.org - place a consistent namespace accordingly, resolve the error above.

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

Hope this helps
