The Apache log4net library is a tool to help the programmer output log
statements to a variety of output targets. log4net is a port of the
excellent Apache log4j framework to the Microsoft(R) .NET runtime.
Apache log4net 2.0.8 fixes a LockRecursionException that could happen
inside the FileAppender under certain circumstances. It also adds
support for LogicalThreadContext to the .NET Standard build based on
AsyncLocal rather than CallContext.
