How can I return bare result back to WCF client

Question

I have code something like the following:

<OperationContract()>
<Description("")>
<WebGet(Bodystyle:=WebMessageBodyStyle.Bare, UriTemplate:="TestConnection")>
Function TestConnection() As String


Public Function TestConnection() As String Implements ITestSvc.TestConnection
    WebOperationContext.Current.OutgoingResponse.ContentType = "text/plain"
    Return "Connection Success"
End Function

But it returns is <string xmlns='...'>Connection Success</string>

How can I have only "Connection Success" to be returned without XML wrapper. I know that we can do something with MessageEncoder. But, I want to have it available at operation level (certain operations need XML/JSON wrappers and certain operations don't).

Can anyone help me on this?

here is the simplest solution to return plain text. Set response format to xml and set outgoingresponse to text/html. Should do the trick.

[WebGet(ResponseFormat = WebMessageFormat.Xml)]
public string DoWork()
{

    WebOperationContext.Current.OutgoingResponse.ContentType = "text/html";
    return "THIS IS PLAIN TEXT";
}

There is one way how to achieve this if you're dealing with HTTP, it's not exactly nice, but I thought I could mention it.

You can set the return type of your method to void and just output your raw string directly into the response.

[OperationContract]
[WebGet(UriTemplate = "foo")]
void Foo()
{
   HttpContext.Current.Response.Write("bar");
}
