Mono 4.0 was officially released this month. This marks the first version that contains open source code from Microsoft’s CoreCLR project. It also defaults to C# 6, meaning that once again Mono has an RTM version of a new C# compiler before Microsoft.
Developers working on the .NET Core project have added support for the FreeBSD platform. It is now possible run a single .NET assembly across all 4 platforms (Mac OS X, Linux, Windows, and FreeBSD).
A draft of the release notes for Mono 4.0 have been posted. Among other changes, they have started to adopt code from Microsoft’s CoreCLR project. At the same time, they are dropping support for .NET 4.0 and earlier. Mono will now only build .NET 4.5 compatible assemblies.
Microsoft announced at connect() that .NET Core would be open sourced and it would provide a single code base to support all platforms, including Windows, Linux and Mac OSX. Recently, Immo Landwerth, Program Manager at Microsoft, has given more details about what .NET Core is and how it will provide "the foundation for all future .NET platforms."
The Unreal Engine joins Unity with C# support thanks to Xamarin's new Mono for Unreal Engine. This extension enables developers to create Unreal Engine just using C#.
Mono 3.8.0 was released last week. It comes with several performance and scalability improvements across the runtime, as well as finishes the Windows port.
Mono 3.6 has been released, and features an improved debugger, several bug fixes, and Nuget for Mac users.
The Mono project has focused on conformant code since its inception. Now the project is adding dedicated resources to focus on improving performance.
In this interview we talk to open source developer Philipp Crocoll about Keepass2Android. Besides its features as a password store, this project is a good case study for combining Java and C# in a single Android application.
Mono 3.2.7 is out, with a lot of new features such as an improved JIT, new interpreter for LINQ, use of native instructions for 64 bits, and more.
In order to support 64-bit iOS and OSX, Xamarin has to make some breaking changes to the way it implements the mapping between C# and Objective-C libraries. Rather than being mapped to 32-bit types, NSInteger and CGFloat are now mapped to the new platform-specific data types nint and nfloat.
Mono 3.2 was released last month with several GC improvements, dev improvements and more. Several other items such as PlayScript integration and CppSharp are already work-in-progress.
ILNumerics, a high performance numerical calculation library for .NET, now offers a NuGet package with “Any CPU” support. In a separate release called ILView, a 3D visualization tool with REPL support has been announced.
Crypto Obfuscator for .Net v2013 R2 includes support for code masking, constant field removal, Visual Studio 2012. It also includes Linux and Mono support for automatic exception reporting service including several new additions, improvements, changes and bug fixes.
Google has released a new beta of their SDK known as the Google APIs .NET library. This SDK is being offered as a Portable Class Library and covers 45 of Google’s APIs. This allows Google to offer one DLL that works across .NET, WinRT, Windows Phone, and Silverlight.
