Mono 2.0 Released

The Mono project, an open source initiative sponsored by Novell, today announced the availability of Mono 2.0, an open source, cross-platform .NET development framework. Mono 2.0 provides all the necessary software to develop and run .NET client and server applications on Linux, as well as other operating systems. The new Mono 2.0 release is now compatible with the desktop and server components of version 2.0 of the Microsoft .NET framework and features the Mono Migration Analyzer (MoMA), an analytical tool for .NET-to-Linux migrations.

According to an IDC study, nearly 50 percent of IT decision makers, developers and architects surveyed, reported that they use Microsoft .NET as the application technology platform on which their mission-critical applications (excluding email) run. With Mono 2.0, developers can leverage their existing investment and skill sets to build .NET 2.0 applications for deployment on a variety of platforms, including Linux, Solaris, Unix, and Mac OS X.

"Mono 2.0 gives .NET developers the freedom to run their applications on a wide variety of operating systems, including Linux, MacOS, and Unix," said Miguel de Icaza, vice president of Development Platforms at Novell and maintainer of the Mono project. "Mono 2.0 benefits a wider range of developers, ISVs and end-users by allowing them to write their applications once and run them on any OS platform, dramatically increasing portability and expanding their market reach."

Mono 2.0 now includes MoMA, the Mono Migration Analyzer. MoMA, which runs natively on .NET or on the Mono framework, helps developers quantify the number of changes required to run their .NET application in a Linux environment. In an analysis of 4600 .NET applications using MoMA, 45 percent of the applications required no code changes to work with Mono. An additional 24 percent of the applications were shown to require fewer than six code changes to run on Mono.

One of the most recent successful uses of the Mono framework is the rapid development of Moonlight, an open-source, Mono-based plug-in version of Microsoft Silverlight, which is used to create and host next-generation, rich interactive applications. Linden Labs also uses Mono in the development of its Second Life project to improve the stability and speed of scripts -- particularly calculation-intensive ones.

New features available in Mono 2.0 include:

  • Easy installation. A one-click install feature for SUSE Linux Enterprise and openSUSE, as well as easy-to-use installers for many of the other supported platforms, including Windows and Mac OS X.
  • Comprehensive platform, hardware and API support. The Mono framework supports a variety of platforms, including Linux, Mac OS X, Solaris, BSD and Windows; a variety of hardware options, such as x86, AMD 64, IA-64 (Itanium 2), EMT 64, PowerPC, ARM, S390 and S390x, SPARC and SPARC 9; all Microsoft .NET 2.0 APIs, including ASP.NET, ADO.NET and Windows.Forms; and C# 3.0 compiler with LINQ support.
  • Performance upgrades. Improves scaling and performance for ASP.NET, ADO.NET and Mono runtime.
  • Useful downloads. A Virtual Machine image that comes with a ready-to-use development environment, as well as many open source Web and desktop .NET applications, including the ASP.NET Starter Kits and other demos. An updated version of the MoMA tool, with improved reporting, is also available.

Steve G. Bjorg, CTO at MindTouch says tha, "MindTouch built their open source enterprise collaboration and integration platform, Deki, on the Mono framework. MindTouch Deki enables customers to 'webify' legacy applications, bridge multiple applications with a common interface and provide a more usable interface to systems and databases. Since the core of MindTouch Deki is implemented in C# and deployed to Linux using Mono, we are excited to see Mono 2.0 adding C# 3.0 compiler support, including support for Language Integrated Query (LINQ)."
