Warning: The optional WSDL extension element 'body' from namespace 'http://schemas.xmlsoap.org/wsdl/soap/' was not handled

I'm using Visual Studio 2010, .Net4, Silverlight(4.0.50826.0).

I created a WCF service and I`m trying to create a proxy with SlSvcUtil like:

SlSvcUtil.exe /serializer:DataContractSerializer http://192.128.09.26:8080/Server?wsdl /out:C:\Projets\Client\dService.cs /config:C:\Projets\Client\ServiceReferences.ClientConfig

When I add some methods with customer type and also they have some attributes I got this msg:

Warning: The optional WSDL extension element 'body' from namespace 'http://schemas.xmlsoap.org/wsdl/soap/' was not handled.

XPath: //wsdl:definitions[@targetNamespace='http://tempuri.org/']/wsdl:binding[@ name='BasicHttpBinding_IService']/wsdl:operation[@name='GetDefinitionsHavingFre']/wsdl:output

If I ignore the warning and I try to use the class I get a NullException error when I call any method.

If I change the option /Serializer:XmlSerializer or any other option Its possible create the proxy correctly but I get a lot of null references in the visual studio, so Its necessary to add the correct .dll.

If I add: System.ServiceModel from Silverlight -the xmlserializerformatattribute doesn't exist System.ServiceModel from .NET -the ChannelBase doesn't exist

If I didn't use the customer method my service works fine, so my question is has silverlight some limit when use customer types or methods with attributes ?

Someone has some clue what could be done to solve this ?

Thanks,

I Found the problem.

After creating the proxy with SlSvcUtil and adding the .cs in my project in Visual Studio I got this error:

The type or namespace name 'XmlSerializerFormatAttributeAttribute' does not exist in the namespace 'System.ServiceModel' (are you missing an assembly reference?)

First of all I tried change the System.Service.Model from the Silverlight version to the .Net version, but I got other errors.

So I found somewhere that was necessary, use /serializer:DataContractSerializer in the SlSvcUtil; after that this error was solved. However I got a WSDL warning when the proxy is generated.

SOLUTION

  1. I created the proxy using the following command:

    SlSvcUtil.exe http://192.128.09.26:8080/Server /out:C:\Projets\Client\dService.cs /config:C:\Projets\Client\ServiceReferences.ClientConfig

    Then the I got this error in Visual Studio:

    The type or namespace name 'XmlSerializerFormatAttributeAttribute' does not exist in the namespace 'System.ServiceModel' (are you missing an assembly reference?)

  2. I added the following dll:

    • System.Xml.Serialization.dll - (Runtime Version v2.0.50727)

Conclusion

Visual Studio wasn't able to find the reference inside the ServiceModel.dll and the ServiceModel was there so I never thought to add another .dll because the correct dll was already added.

Just yesterday I tried add the System.Xml.Serialization.dll and now everthing works fine.
