1) A project called NLogViewer is mentioned on some websites, but it looks like it's outdated and/or not supported anymore.
2) There are some basic viewer applications available from third-parties, but those aren't part of the project.

When searching for this page, usual search words that are used include NLog vs. log4net, log4net vs. Enterprise Library (also calledLogging Application Block). Log4net is also often called log4n (which is actually wrong). Any suggestions?
