Thanks for the tip. ILSpy seems to be a very helpful tool. There were several issues, but basically I had set the EmbeddedResource property on the messages.xml file, when what was needed was to set that property to 'none' and generate a 'messages.resources' file with MsgGen, which was added to the project, along with the class file, with the EmbeddedResource set on the messages.resources file.
Code in my prior post, which resulted in the listed exception and stack trace was creating a messages.res file which had no strings in it. So while the empty message.res 'property' and the 'messages.xml' embedded property (as displayed by ILSpy, both had the same URI '<namespace>.Data.Messages' the code could not find the string in the empty container resulting in the candle {0,0} exception and the embedded messages.xml was not a valid resources format. I now have messages derived from WixErrorEventArgs, WixWarningEventArgs, and WixVerboseEventArgs displaying in the Output window at compile time of the 'host' project. The later 'Verbose' message at Level="Information" is only displayed when the host project's property has Verbose checked. Is there a way to display an Information message to the Output window, without having to set the 'Verbose' property and without it being either an Error or a Warning. I am thinking of a message in the Output log (which would be archived as a record of the build) which simply states the version of the my compiler extension which was used at the time of the build. Thanks for the assistance!
