- A new EntLibLoggingProxyTraceListener class. This trace listener is designed to be used in WCF’s System.ServiceModel trace source, which is configured within the <system.diagnostics> section. This trace listener receives WCF messages logged to this trace source, wraps them in an XmlLogEntry class, and forward them to the Logging Application Block where it can be processed according to the application block configuration.
- A new XmlLogEntry class, which derives from LogEntry but includes a new Xml property that preserves the original XML data provided by WCF.
- A new XmlTraceListener class, which derives from the .NET XmlWriterTextWriter class. This class can extract XML data from an XmlLogEntry class
That is all I have managed to find regarding the WCF features of EntLib3. The online MSDN docs contains mostly "new WCF features added to the ____ Application Block" statements and no code samples.
