One benefit caught my eye, but was not explained:

"Much easier to manage platform dependencies in project files and with self-contained application publishing."

Anybody know anything about this? I frequently deal with applications that have platform specific components, and it's a real pain. Sometimes the platform specific code is a platform-specific native dll that gets called from the same P/Invoke wrapper, sometimes it's two different managed implementations of the same interface, sometimes it's both. It'd be great if this sort of thing got easier to do.
