The Xamarin Evolve 2014 event taking place these days in Atlanta, US, has produced a number of news related to the cross-platform tools Xamarin makes: Android Player – a hardware accelerated Android simulator-, Sketches –a REPL-like environment-, and Profiler –a C# code profiler-.
As the next version of C# gets closer, features that are not quite ready have to be cut. The features. Newly removed from the list are primary constructors and declaration expressions.
Windows App developers have a new way to utilize GPU to accelerate their 2D-based graphical code. New Windows Runtime API Win2D provides Universal Apps on Windows Phone and Windows Store apps a way to access DirectX without resorting to 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.
The Bing Developer Assistant is a new plugin for C# developers to enable effective searches for code samples from within Visual Studio. Rather than requiring a context switch to a web browser, the plugin lets developers make code searches while they work.
The ASP.NET vNext runtime uses the Rosylyn compiler to compile and load the C# sources before running them. David Fowler shows how you can leverage the DI-by-design approach of KRuntime to inject support for your own language.
Another concept from functional programming languages making its way to C# and VB is what’s known as pattern matching. At first glance pattern matching looks like a switch/select block, but it is much more powerful.
Xamarin has forked Cocos2D-XNA, a 2D/3D game development framework, creating a cross-platform library that can be included in PCL projects.
A common pain point in .NET programming is the amount of boilerplate code necessary to implement immutable objects such as explicitly defined backing stores for each property. Under a new draft specification, C# and VB will be adding what they are calling a “record class” that eliminates most of the effort.
As promised, Microsoft has released newly acquired Visual Studio plugin UnityVS for free to developers using any recent paid edition of Visual Studio. This plugin greatly improves developers working with the Unity game development system.
