As additional evidence that Microsoft is welcoming cross-platform development, a prematurely revealed Microsoft blog post revealed that Microsoft is working on a version of Visual Studio for Mac.
The idea isn’t that you will use your Mac to create Windows applications, but that you can include Mac users in your pool of developers as you write Android, iOS, and Mac apps with Xamarin and .NET Core. And Mac and Windows users can share projects, which could be very important to a dispersed team. This is seen as a way for Microsoft to emphasize cloud development on Azure without the focus on Windows development.
You should hear an official announcement and receive a preview download of Visual Studio for Mac sometime during Microsoft’s Connect() conference, which runs November 16th through 18th.
