Logica

Answer 1

Stephen confirms that this works on .Net 4.5 and Win8/2012. Not tested on other platforms, and known not to work on at least some of them. So the answer is that Microsoft got their game together and fixed the underlying issue in at least the most recent version of .Net and the async compiler.

So the answer is, it does work, just not on older .Net versions. (So the log4net project can't use it to provide a generic NDC.)
