.NET Core - What's Coming in .NET Core 3.0 @ MSDN Magazine
".NET Core 3.0 is the next major version of the .NET Core platform. It includes many exciting new features, such as support for Windows desktop applications with Windows Forms (WinForms), Windows Presentation Foundation (WPF) and Entity Framework 6. For Web development it adds support for building client-side Web applications with C# using Razor Components (formerly known as Blazor). And it includes support for C# 8.0 and .NET Standard 2.1.
We are adding support for Internet-of-Things (IoT) scenarios with .NET Core 3.0. You’ll now be able to program hardware pins (for controlling devices and reading sensor data) on the Raspberry Pi and similar devices, and communicate via serial port on all supported OSes (for example, with a Raspberry Pi or Arduino). We’re also adding IoT device support for ARM64 in this release, to complement the ARM32 capability that’s already in place.
.NET Core 3.0 will also fully support ML.NET, our open source machine learning framework built for .NET developers. ML.NET powers products like Azure Machine Learning, Windows Defender and PowerPoint Design Ideas."
