Mono Project The Mono project has released Mono 2.0. As most of you will know, Mono is an open-source implementation of Microsoft's .NET framework for Linux, Mac OS X, Windows, and other operating systems. The 2.0 release comes packed with new features, the main ones being the compiler upgrade to C# 3.0 with support for LINQ, as well as the inclusion of ADO.NET 2.0, ASP.NET 2.0 and System.Windows.Forms 2.0. The release notes detail all the changes and new features.

RE[2]: Just say no

Member since:

Mono has improved in performance quite a lot since 1.2.6 and is quickly gaining ground on Java6-server, especially with the new Linear IR branch which you can read about at

The Linear IR branch is poised to make it into Mono 2.2 and is already as much as 30% faster than Mono 2.0 and there are lots more optimizations that can be done (and indeed, just last week SIMD optimizations were implemented which increase the performance even more).

That is excellent news. Do you have a link to any benchmarks ? (especially against JRE 1.6u10).

Mono is also fully open source.

As far as waivers from Sun, I am unaware of these. Could you provide a link to these waivers?

I have never seen nor heard of any such waivers before.

See section 2. That is a patent grant for all implementations of the Java specification (and you don't have to ask Sun for permission to use it). However you don't have the right to call it "Java" unless you pass Sun's compatibility tests (since it wants to avoid fragmentation). Unfortunately it doesn't look like Microsoft will ever do this for .NET ;)

This is all subjective, and let's not forget that Mono can continue even if Microsoft moves to something else next week, next month, next year, or next decade.

Mono is, after-all, a Free Software project that anyone can continue to maintain. It is not in any way dependent upon the life span of Microsoft's .NET just as C in Linux has been in use long after much of the Windows world switched to C++.

Completely true. What you're missing is that while Mono would soldier on as soon as there is fragmentation then adoption would be split. While it is not absolutely necessary to avoid this (after all, part of the point of Free Software is the 'right to fork'), this really dissipates developer effort and confuses users. It should be avoided for practical reasons.

Despite my preference for Java I'd like to thank you once again all your efforts with Mono (the community still needs it). It's nice to have choice.
