The Mono Project has reached a couple of milestones recently: the
release of version 1.0 of the MonoDevelop IDE, and the
release of Mono 1.9, the beta for Mono 2.0. (Mono releases do not track .NET releases exactly, so Mono 2.0 will include a mix of features from .NET 2.0 and later versions). This advances the ability of open source developers to use the .NET platform, but how much does that matter?
