Problem with web reference

I have tried using BizTalk, a Windows app and a Web app to add a web
reference to a WCF service that was generated using the Web Service Software
Factory.

I need to do this via a web reference because ultimately I'll be using
BizTalk and I don't want to have to use proxy classes as this will require
variables and hard coding in the orchestration that will be calling the WCF
service which makes it more of a problem when deploying.

The operation generated in the WSSF has a service implementation with a
method:

public bool PublishRequest(PublishMetaData request)

where PublishMetaData is a business entity within the service.

When I add this service (via the .svc in the web references dialogue) in any
application the method signature changes to:

public void PublishRequest(PublishMetaData request, out bool
PublishRequestResult, out bool PublishRequestResultSpecified)

Can anyone tell me why this would happen and more importantly how I can stop
it as I NEED the signature to be as exposed in the service implementation?
The reason I NEED it to be the same is because BizTalk web service support
doesn't seem to extend to "out" parameters rather like it doesn't extend to
arrays as return types.

The service is bound using basicHttp binding.

TIA,

Martin

Hello, Competitive!

What version of WCF do you use? RTM?

This is serializer behavior - it thinks that bool return type can be null.
To resolve this issue you can add XmlSerializerFormat attribute to
the contract ( interface ) .

Have a look for more info (

Vadym,

Many thanks that seems to have done the trick with web applications.

BizTalk is still failing to add the reference but I'm guessing this is not
something to do with the service as such, but more something specific to
BizTalk as adding it to a web applicaiton works fine.

Thanks for the help and the reference, it'll be going on my project blog
today!

Cheers,

CD
