VB Magic

I came across this problem over the holiday period. The full error was:

Warning    4    Custom tool warning: Cannot import wsdl:portType
Detail: An exception was thrown while running a WSDL import extension: System.ServiceModel.Description.DataContractSerializerMessageContractImporter
Error: Type 'Newtonsoft.Json.Linq.JToken' is a recursive collection data contract which is not supported. Consider modifying the definition of collection 'Newtonsoft.Json.Linq.JToken' to remove references to itself.
XPath to Error Source: //wsdl:definitions[@targetNamespace='http://tempuri.org/']/wsdl:portType[@name='Ixxxxx']    C:\projects\Tyrannt RPG\Tyrannt\Tyrannt.Client.Web\Service References\CodexUpdateServiceReference\Reference.svcmap    1    1    Tyrannt.Client.Web

After doing a bit of searching I found the way to fix it was to remove the Newtonsoft.Json.Linq.JToken from the “Resue Types”:

Right click the service reference…

Select the Reuse Types in Selected References option and tick all the boxes except the Newtonsoft.Json package.

This was the blogpost that helped me solve it “Type ‘Newtonsoft.Json.Linq.JToken’ is a recursive collection data contract” While Adding Service Reference in VS2012
