Mono 2.0包括ADO.NET 2.0/ASP.NET 2.0/Windows.Forms 2.0/System.XML 2.0/System.Drawing/Linq/GTK#等类库的实现。这个release比1.x更为完整和成熟了。其中，C#编译器对C# 3的支持已经完整；标准库方面，WinForms 2.0的API已经完整支持，LINQ和ASP.NET的支持也比之前更为完善；执行引擎开始共享泛型代码后占用内存量减少了。
新版的主站界面也十分漂亮
几年前要是谁说CLI是跨平台的，以Mono来举例的话，或许会被强烈抨击Mono不现实，也就是在去年园子里就爆发过一场激烈的争论不要奢望.NET能够跨平台。但现在的Mono已不同于昔日的，可谓今非昔比。加上不断成熟的MonoDevelop，在Windows之外做CLI平台上的开发也越来越现实了。
Mono越来越接近产品状态了。只要不用P/Invoke，许多.NET应用都能as-is在Mono上运行了。贴一个Mono特性对比表：
