The type '' was not expected. Use the XmlInclude or SoapInclude attribute to specify types that are not known statically

Hi,

When my Soap Web Service is called, it does everything what it should but generates the following soap error message:

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
   <soap:Body>
      <soap:Fault>
         <soap:Code>
            <soap:Value>soap:Receiver</soap:Value>
         </soap:Code>
         <soap:Reason>
            <soap:Text xml:lang="en">System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.InvalidOperationException: There was an error generating the XML document. ---> System.InvalidOperationException: The type BBTSerenaIntegration.ZMFWebservice_PackageLifeCycleServices.response was not expected. Use the XmlInclude or SoapInclude attribute to specify types that are not known statically.

         </soap:Reason>
         <soap:Detail/>
      </soap:Fault>
   </soap:Body>
</soap:Envelope>

I have tried to add the includes as suggested in the error message but both entries didn't solve the issue:
[XmlInclude(typeof(ZMFWebservice_PackageLifeCycleServices.response))]
[SoapInclude(typeof(ZMFWebservice_PackageLifeCycleServices.response))]

In the attachments you can find the Soap Web Service (BBTSerenaIntegration.asmx.cs) and the Operations class (ZMFOperation.cs) which is being called by the Soap Web Service.
ZMFWebservice_PackageLifeCycleServices is a reference to a Soap Web Service.

Thanks in advance for all the assistance.

I guess you have done wrong!

    [SoapInclude(typeof(ZMFWebservice_PackageLifeCycleServices.response))]
    public Output freezePackage(String package)

Open in new window


Attribute [SoapInclude] is not required for internal class operation.Check here.

What I suggest instead,
Place a break point at return statement at below line of code.
    ZMFOperations zmfOperations = new ZMFOperations();
    Output output = zmfOperations.freezePackage(package);
    return output;

Open in new window


Check what's
Type

Open in new window

of "output" object (you can use object.GetType() to identify that) and add below line of code in BBTSerenaIntegration.asmx.cs
    [SoapInclude(typeof(TYPE_THAT_YOU_RECEIVED_WHILE_DEBUGING))]
    public Output ZMF_FreezePackage(String package)

Open in new window


This shall work. Let me know if issue still persist.
