Wcf: Error: Style on header does not match expected style Rpc

[outadoc]

I'm trying to generate a WCF reference to an internal SOAP service into a .NET 4.6 project. I get this error whenever I try to import the WSDL:

Importing web service metadata ...
Number of services found: 1
Restoring NuGet packages ...
Building solution ...
Scaffolding service reference code ...

Error: Style Document on header id does not match expected style Rpc.
Error: Style Document on header version does not match expected style Rpc. 
Error: Style Document on header type does not match expected style Rpc.
Error: Style Document on header mode_envoi does not match expected style Rpc.
Error: Style Document on header mode_production does not match expected style Rpc.
Error: Style Document on header format does not match expected style Rpc.
Error: Style Document on header piecesJointes does not match expected style Rpc.
Error: An unknown error occurred while invoking the service metadata component.
Failed to generate service reference.

I stumbled upon this thread and since we mostly run Java apps, it doesn't seem unlikely that there's an incompatibility somewhere. Nonetheless, I'm wondering if it should be considered or not as a bug here.

More details: it should be of type Document and works correctly if that's fixed. However, when adding a service reference with the old system, it works fine; the errors are only considered as warnings. This is only a problem when using the WCF Web Service Reference Provider extension.

@outadoc Sorry to hear that you are running into an issue! We will try to repro locally and identify the root cause.

Hi @outadoc

Visual Studio 15.5 Preview 2 is now available and we provided several fixes to the tool in this update. Would you be able to try your scenario with this version of VS and if you continue to hit this problem provide us with more details? if possible for you, the service url or wsdl files?

thank you again,
Miguel Lacouture

Hi @mlacouture, unfortunately I won't be able to test this out until at least the 13th; I hope that's okay.

Thank you for the follow-up!

[mlacouture]

@outadoc , in the meantime if you can provide us with a wsdl file we can use to reproduce this issue that would be great. thanks,

Hi, sorry for the delay. Here's a sample (obfuscated) WSDL:

Hi @outadoc

thank you for providing the service wsdl, unfortunately it contains an import reference to a secure site so I cannot download the full schema. can you use your browser or svcutil.exe to download the metadata as a single wsdl by providing the '?singlewsdl' query?

thanks,

[outadoc]

@outadoc, thank you very much for the updated wsdl files.

I just verified and confirmed we have a fix for this issue, it will be available in Visual Studio 2017 15.6 Preview 1 which is to be release in less than a month from now.

Hi @outadoc, please let us know if you still need help with this issue, closing for now. Thanks again.
