    copied!<p>I'm trying to set the MessageHeader of a message that my Biztalk orchestration is sending to WCF. The Message Contract looks as follows in the WCF project.</p> <pre><code> [MessageContract(IsWrapped = true, WrapperName = "PerformTransformationRequestWrapper", WrapperNamespace="http://www.iasreo.com/integration/servicetypes")] public class PerformTransformationRequest { [MessageHeader(Namespace = "http://www.iasreo.com/integration/servicetypes")] public string Version { get; set; } /// &lt;summary&gt; /// /// &lt;/summary&gt; [MessageHeader(Namespace = "http://www.iasreo.com/integration/servicetypes", MustUnderstand = true)] public TransformType TransformType { get; set; } /// &lt;summary&gt; /// /// &lt;/summary&gt; [MessageBodyMember(Namespace = "http://www.iasreo.com/integration/servicetypes")] public System.IO.Stream Payload { get; set; } } </code></pre> <p>TransformType.cs</p> <pre><code>[DataContract(Namespace = "http://www.iasreo.com/integration/servicetypes")] public enum TransformType { /// &lt;summary&gt; /// Transform to Excel /// &lt;/summary&gt; [EnumMember] ExcelTransform = 1, /// &lt;summary&gt; /// Transform to PDF /// &lt;/summary&gt; [EnumMember] PDFTransform = 2 } </code></pre> <p>I'm creating the message to send to Biztalk in a Message Assignment shape and that code looks as follows:</p> <pre><code>xmlDoc = new System.Xml.XmlDocument(); xmlDoc.LoadXml(@"&lt;ns0:PerformTransformationRequestWrapper xmlns:ns0=""http://www.iasreo.com/integration/servicetypes""&gt;&lt;ns0:Payload&gt;GpM7&lt;/ns0:Payload&gt;&lt;/ns0:PerformTransformationRequestWrapper&gt;"); PerformTransformationRequest = xmlDoc; xpath(PerformTransformationRequest, "/*[local-name()='PerformTransformationRequestWrapper' and namespace-uri()='http://www.iasreo.com/integration/servicetypes']/*[local-name()='Payload']") = System.Convert.ToBase64String(System.Text.Encoding.ASCII.GetBytes(Input.OuterXml)); </code></pre> <p>How can I set the Version and TransformType that MessageHeaders in the WCF MessageContract?</p>
