| 1 | By the time you read this, Build—the Microsoft developer conference—will be over and developers will be thinking about how to respond to all that was presented: embrace immediately, watch with slight trepidation or ignore for the moment. For .NET C# developers, the most significant announcement was undoubtedly the release of the next version of the C# compiler ("Roslyn") as open source. Related to that are the language improvements themselves. Even if you don't have plans to immediately adopt C# vNext—which I'll refer to henceforth and unofficially as C# 6.0—at a minimum, you should be aware of its features and take note of those that might make it worth jumping right in. In this article, I'll delve into the details of what's available in C# 6.0 at the time of this writing (March 2014) or in the now open source bits downloadable from roslyn.codeplex.com. I'll refer to this as a single release that I'll term the March Preview. The C#-specific features of this March Preview are implemented entirely in the compiler, without any dependency on an updated Microsoft .NET Framework or runtime. This means you can adopt C# 6.0 in your development without having to upgrade the .NET Framework for either development or deployment. In fact, installing the C# 6.0 compiler from this release involves little more than installing a Visual Studio 2013 extension, which in turn updates the MSBuild target files. As I introduce each C# 6.0 feature, you might want to consider the following: Was there a reasonable means of coding the same functionality in the past, such that the feature is mostly syntactic sugar—a short cut or streamlined approach? Exception filtering, for example, doesn't have a C# 5.0 equivalent, while primary constructors do. Is the feature available in the March Preview? Most features I'll describe are available, but some (such as a new binary literal) are not. Do you have any feedback for the team regarding the new language feature? The team is still relatively early in its release lifecycle and very interested in hearing your thoughts about the release (see msdn.com Roslyn for feedback instructions). Thinking through such questions can help you gauge the significance of the new features in relation to your own development efforts. |
