We are now sharing code between the two stacks. This means that we get to share bug fixes, implementations and performance improvements. It is a process, and is generally going great. The challenge is tha Mono needs to ensure the larger API surface and to avoid regressions on existing behaviors and in some cases we have different substrates that are not identical. I posted a link above with the plan that we have. But Github is a better source of information, you can see there all the shared code in the .sources files in the Mono/mcs/class directories
