Custom tool warnings when using VS2010 service reference

Question

I am trying to get going on using First Data's Global Gateway Web Service API. The first strange thing is that I need to download the wsdl and xsd files to my local machine. Then use the local machine's copy for the service reference. I haven't used many web services, so I figured that was okay.

After adding them and try to compile it I get the following errors:

Warning 1   Custom tool warning: Cannot import wsdl:portType

I tried the "Reuse types in referenced assemblies" mentioned in many places and that doesn't fix it. Has anyone come across this error? How did you fix it?

Answer 1

I found this answer that seems to at least let me continue working. In the mean time, I am open for other ideas.

Update: Quoting the answer for ease of finding it:

Try adding it as .NET 2.0 Web Reference.

Go to Add Service Reference, then click the "Advanced" button. Then you're given to option to add it as a .NET 2.0 Web Reference. I did this, and got it to work. I couldn't via the standard "Add Service Reference"
