Microsoft rolls out Visual Studio for Mac Preview 4

Back in November, Microsoft announced Visual Studio for Mac, releasing its first preview, and promising to add more features in the months ahead. Today, alongside the general release of Visual Studio 2017, Microsoft also rolled out Visual Studio for Mac Preview 4.

"Visual Studio for Mac Preview 4 brings lots of new features, including updates to the Xamarin and .NET Core workloads," Xamarin's Miguel de Icaza explained today. "Preview 4 brings expanded project templates for .NET Core, as well as support for the beautiful new MSBuild .NET Core project format. The Xamarin workload has been updated to include a new iOS Audio Unit wizard, Android binding project operations, and other mobile tooling improvements. This preview also includes NuGet 4.0 support and tons of other bug fixes and performance improvements."

As in Visual Studio 2017, Visual Studio for Mac Preview 4 also brings enhancements to the Xamarin.Forms Previewer, along with new and updated development templates. "We have overhauled all of our iOS, watchOS, and tvOS templates with a flurry of new extensions to make development a breeze," Miguel said.

There are new Connected Services with simplified access to cloud capabilities, and you'll also find the latest SDKs for all major platforms, including Android 7.1 Nougat, iOS 10.2 and watchOS 3.
