Mono 3.0 released

Miguel de Icaza, founder of Xamarin and lead developer of the Mono open-source implementation of Microsoft's .NET platform, announced on his blog today that the third major revision of the Mono framework is now available. Mono 3.0 was released on GitHub on October 18. It adds support for some of the most recently added key features of the .NET platform, incorporates Microsoft's open-source framework for Web development, and beefs up the capabilities of Mono on Mac OS X and iOS. It also lays the groundwork for much more rapid development of features for the Mono platform going forward.

Android ported to C#

Wow. "One crazy idea that the team had at that dinner was to translate Android's source code to C#. Android would benefit from C# performance features like structures, P/Invoke, real generics and our more mature runtime. We decided it was crazy enough to try. So we started a small skunkworks project with the goal of doing a machine translation of Android from Java to C#. We called this project XobotOS." Most of Android's layouts and controls are now in C#. The small benchmark is stunning, but as much as I admire the work, I'm wondering that this like going from bad to worse - from Oracle's Java to Microsoft's C#.

Miguel De Icaza Announces New Company

Two weeks ago we covered the news that the Mono development team were let go kicked out by the new owners of Novel, Attachmate, apparently to move operations to Germany. Miguel de Icazza, founder of Mono, has taken this opportunity to break off on his own and has started a new company, Xamarin, to bring commercial .NET development products to iOS and Android.

Mono Applications Use Unsafe, Tainted Namespaces

For the most time, I've been firmly in the largest camp when it comes to the Mono debate - the 'I don't care'-camp. With patent lawsuits being hotter than Lady Gaga right now, that changed. For good reason, so it seems; while firmly in the 'ZOMG-MICROSOFT-IS-T3H-EVILL!1!!ONE!'-camp, The-Source.com investigated the five most popular Mono applications, and the conclusion is clear: all of them implement a lot of namespaces which are not covered by Microsoft's community promise thing.

Mono LLVM Compilation

Mono from SVN is now able to use LLVM as a backend for code generation in addition to Mono's built-in JIT compiler. "This allows Mono to benefit from all of the compiler optimizations done in LLVM. For example the SciMark score goes from 482 to 610. This extra performance comes at a cost: it consumes more time and more memory to JIT compile using LLVM than using Mono's built-in JIT, so it is not a solution for everyone. Long running desktop applications like Banshee and Gnome-Do want to keep memory usage low and also would most likely not benefit from better code generation. Our own tests show that ASP.NET applications do not seem to benefit very much (but web apps are inherently IO-bound). But computationally intensive applications will definitely benefit from this. Financial and scientific users will surely appreciate this performance boost."

C#, CLI Under Community Promise, Mono Split in Half

We've already seen some heavy discussion on Mono and C# here on OSNews the past few weeks, as it became clear the patent situation regarding the ECMA parts of Mono was anything but faith inspiring. This issue seems to be resolved now: Microsoft has made a legally binding promise not to sue anyone who uses or distributes implementations of said ECMA standards. Following this news, Mono will be split in two; the ECMA standard parts, and the rest.

Why Mono Doesn’t Suck

A Mono developer responds to a request for "a calm presentation of why Mono is desirable, why it is not a threat, and why it should be included in Ubuntu by default" answering the three questions individually, then attempting to address general anti-Mono sentiment.

Mono, Moonlight: Patent Encumbered, Or Not?

If there is one technology in the Linux world that ruffles feathers whenever it's mentioned, it's Mono, the open source .Net clone. Since .Net comes out of Microsoft, and has some patents encircling it, it is said to be a legal nightmare. Supposedly, you can obtain a "royalty-free, reasonable and non-discriminatory" license from Microsoft regarding the patents surrounding Mono. iTWire decided to look at just how easy (or hard) it is to get such a license. Turns out it's kind of hard.

Mono 2.2 May Overtake .NET in Some Critical Categories

The Mono Project releases version 2.2 this week with full support for SIMD extensions being one of the more interesting features (Betanews article). The extension allows SIMD code to be accelerated above and beyond the speed of past Mono and current .NET releases. Johnathan Allen from InfoQ impresses the significance of the latest Mono release in a blog entry. "It represents something bigger; Mono is outgrowing the standard. Mono is not just playing catch-up any more, it is trying to move past the CLR in many areas. And as an open source project, they can slip in new libraries at a much faster clip than Microsoft. Instead of trying to build everything themselves, they can simply pick up mature projects like Mono. Options or the collection library C5 and include them in the standard release."
