WCF message body showing <s:Body>... stream ...</s:Body> after modification

Trying to use MessageInspector to modify the message before the wcf service through the proxy. However while debugging the message body does not gets copied and body shows

 <s:Body>... stream ...</s:Body>

What is the problem with the code?

public class CustomWCFMessageInspector : IClientMessageInspector
{
    public object BeforeSendRequest(ref Message request, IClientChannel channel)
    {
        request = ModifyMessage(request);
        return null;
    }

    private Message ModifyMessage(Message oldMessage)
    {
        Message newMessage = null;
        MessageBuffer msgbuf = oldMessage.CreateBufferedCopy(int.MaxValue);

        Message tmpMessage = msgbuf.CreateMessage();
        XmlDictionaryReader xdr = tmpMessage.GetReaderAtBodyContents();

        XDocument xd = ConvertToXDocument(xdr);

        EmitTags(xd);

        var ms = new MemoryStream();
        var xw = XmlWriter.Create(ms);
        xd.Save(xw);

        xw.Flush();
        xw.Close();

        ms.Position = 0;
        XmlReader xr = XmlReader.Create(ms);

        newMessage = Message.CreateMessage(tmpMessage.Version, null, xr);
        newMessage.Headers.CopyHeadersFrom(tmpMessage);
        newMessage.Properties.CopyProperties(tmpMessage.Properties);

        return newMessage;
    }

Here is solution: if you call Message.ToString() you will get

..stream..

Instead use System.Xml.XmlWriter. Here is a sample:

MessageBuffer buffer = reply.CreateBufferedCopy(Int32.MaxValue);
Message msg = buffer.CreateMessage();
StringBuilder sb = new StringBuilder();
using (System.Xml.XmlWriter xw = System.Xml.XmlWriter.Create(sb))
{
    msg.WriteMessage(xw);
    xw.Close();
}
Console.WriteLine("Message Received:\n{0}", sb.ToString());

The problem was that the newMessage body was not shown in the watch window after doing ToString()

Created the buffered copy of the message to be shown in the debugger.

MessageBuffer messageBuffer = newMessage.CreateBufferedCopy(int.MaxValue);
Message message = messageBuffer.CreateMessage();

So there is No problem in the code. It is just that the debugger is not showing the message body as mentioned in the link below

in the Accessing the Message Body for Debugging section.

I suspect ToString will return what you are getting. ToString is often used for debugging, and hence only shows you basic information about the object. You need to do something like this in ConvertToXDocument:

XDocument x = XDocument.Load(xdr);
