I was going through the Extensibility Hands-on Labs for Microsoft Enterprise Library 5.0 and found an error in the "Lab 2: Custom Logging Trace Listener" lesson. It applies to exercises 2,3 and 4 in the lab. I searched through the issues tracker on the CodePlex site but could not anything related to this error.
Overview of the problem:
When attempting to add the trace listener via the Enterprise Library Configuration tool I get a validation error : “The field ListenerDataTypeName is missing a required value”. Therefore the configuration tool will not save the config file.
Looking for suggestions.
