Mono 3.0 released
On 10/22/2012 Miguel de Icaza blogged about the latest release of the Mono .NET project. As you may already know, the Mono project is an open source port of the Microsoft .NET framework which allows cross platform support for .NET applications with support for such systems as Linux and Mac OS X / iOS.
The Mono 3.0 release includes improved support for asynchronous programming which was introduced in .NET 4.5. These improvements help developers to create fast, responsive applications. The ability to keep the user interface of an application responsive while executing time consuming tasks is extremely important as applications are moving to smart phones and tablets. The release also includes improvements that will strengthen Mono's support for Mac OS X and iOS development.
Developers can also look forward to added support to Microsoft's open sourced stacks which includes technologies like:
ASP.NET MVC 4, ASP.NET WebPages, Entity Framework, Razor View Engine, and System.Json.
