Mono Wiki

One of the frequently asked questions for Mono is, "What has Mono implemented? What does Mono support? What's missing?". This article will detail its features and list some upcoming plans.

Current plans are to work on bug fixing, complete new APIs from 3.5SP1, performance issues, and getting some key applications running.[1]
