Hi there! Rajen Kishna, Product Manager on Visual Studio for Mac here. Visual Studio for Mac is a full-featured IDE to create apps, games, and services for mobile, web, and cloud. Creating mobile apps with Xamarin and C# is definitely one of the workloads available, but there's a lot more with .NET Core, Unity, and Azure. You can view .NET Core as the cross-platform implementation of .NET you can code against and share code across apps and web on Windows, Linux, and macOS. Hope that helps clear things up!
