WCF service method unavailable in WCF Test Client because it uses type

I am trying to use the WCF Test Client to test a WCF service I have built.

The service has one method "SubmitRequest".

[OperationContract]
Response SubmitRequest(Request request);


When I load up the WCF Test Client, the method is grayed out with the message "This operation is not supported in the WCF Test Client because it uses type WcfLibrary.Objects.Request

Below is the type definition, does anyone see anything wrong?

[DataContract]
public class Request
{
[DataMember]
public string LoanNumber { get; set; }

[DataMember]
public string ClientCode { get; set; }

[DataMember]
public Region Region { get; set; }

[DataMember]
public RequestType RequestType { get; set; }

[DataMember]
public List<RequestParameter> RequestParameters { get; set; }

[DataMember]
public List<MspWebCallType> MspWebCallsForXmlRequest { get; set; }

[DataMember]
public Hashtable XmlRequestParameters { get; set; }

public Request(string loanNumber, string clientCode, Region region, RequestType requestType, List<RequestParameter> requestParameters)
{
LoanNumber = loanNumber;
ClientCode = clientCode;
Region = region;
RequestType = requestType;
RequestParameters = requestParameters;
}
}

[DataContract]
public class MspWebCallType
{
[DataMember]
public string WebService { get; set; }
[DataMember]
public string Operation { get; set; }
[DataMember]
public string Version { get; set; }
[DataMember]
public Hashtable Parameters { get; set; }
[DataMember]
public Msp.FavReadViews FAVReadViewIndicator { get; set; }
[DataMember]
public Msp.DsReadIndicators DSReadInidicator { get; set; }
}

[DataContract]
public enum Region
{
[EnumMember]
P2,
[EnumMember]
PROD
}

[DataContract]
public enum RequestType
{
[EnumMember]
None,
[EnumMember]
XmlRequest,
[EnumMember]
SomeOtherRequestType
}

[DataContract]
public struct RequestParameter
{
[DataMember]
public string ParameterName { get; set; }

[DataMember]
public string ParameterValue { get; set; }
}


Thanks.

EDIT w/ answer...

The operation was not available via the WCF Test Client because the type MspWebCallType had a property of type Hashtable. Once I removed this property it fixed the issue. Thanks for everyone's help.

Answer

The following is a list of features not supported by WCF Test Client:

  • Types: Stream, Message, XmlElement, XmlAttribute, XmlNode, types that implement the IXmlSerializable interface, including the related XmlSchemaProviderAttribute attribute, and the XDocument and XElement types and the ADO.NET DataTable type.

  • Duplex contract.

  • Transaction.

  • Security: CardSpace , Certificate, and Username/Password.

  • Bindings: WSFederationbinding, any Context bindings and Https binding, WebHttpbinding (Json response message support).

Check Msp.FavReadViews and Msp.DsReadIndicators to ensure they comply.
