During a Silverlight migration project from VB6 I was trying to add a WCF reference,
everything seemed to work in the wizard but no code was generated.
After reviewing the Warning messages, i found that some said:
Custom tool warning: Cannot import wsdl:portType
What I did to solve this issue?
1. Right click on your service reference
2. Select Configure Service reference
3. Uncheck the option that says Reuse types in referenced assemblies.
4. Press OK
After that VS generated the code and I could use the WCF service.
