With the and iOS 5 release today and the MonoDevelop 2.8 release last week, there is also a new MonoTouch 5.0 released that binds the two and allows you to develop iOS 5 using Mono.
Almost like a mirracle: on the iOS 5 release day, MonoTouch 5 gets released. Lot’s of new stuff to play with, just read the announcement :)
Quote: “If you already have MonoTouch, simply launch MonoDevelop and you will be prompted to update – it’s that easy!”
Be sure to also read the new MonoTouch 5 documentation on new iOS 5 features and the comprehensive API diff between MonoTouch 4.2 and 5.0.
