The answers on that SO post you linked which mention the ILogger interface are variations of what you probably want for application wide error logging, though they're giving a bare minimum implementation. I was able to write an .AddYourLogger() for the application I'm building, like what's called in the codeblock below, in about an hour by learning from the example of the Elmah logger.
