I don't want my application to have any unneeded dependencies, log4net being one such dependency. As such, are there any thin third-party libraries or will I need to write my own?
Also, for those of you who need to have the "Why?" question answered, it comes down to the fact that I find 100k of binary code to conditionally write a single line of text to a file (my use case) to be a bit on the excessive side.
