Unable to create channel when operation is using typed messages with RPC/Encoded

I’m trying to consume a service that requires an operation to be attributed with RPC / Encoded. This is an example: [XmlSerializerFormatAttribute(Style=OperationFormatStyle.Rpc, SupportFaults=true, Use=OperationFormatUse.Encoded)] PingResponse Ping(PingRequest request);

When trying to create a channel of a service that implements the above operation I get the SFxTypedMessageCannotBeRpcLiteral error.

This may be due to the XmlSerializerOperationFormatter constructor passing isEncoded as false to the base class constructor (OperationFormatter), instead of using info from xmlSerializerFormatAttribute.

public XmlSerializerOperationFormatter(OperationDescription description, XmlSerializerFormatAttribute xmlSerializerFormatAttribute, MessageInfo requestMessageInfo, MessageInfo replyMessageInfo) : base(description, xmlSerializerFormatAttribute.Style == OperationFormatStyle.Rpc, false/*isEncoded*/) { _requestMessageInfo = requestMessageInfo; _replyMessageInfo = replyMessageInfo; }

Is RPC/Encoded not supported?
