Microsoft has announced the release of .NET Core 3.0, bringing along a plethora of improvements, as well as compatibility with existing projects so developers aren't starting from scratch. Here's what Microsoft had to say on their .NET Blog:
We’re excited to announce the release of .NET Core 3.0. It includes many improvements, including adding Windows Forms and WPF, adding new JSON APIs, support for ARM64 and improving performance across the board. C# 8 is also part of this release, which includes nullable, async streams, and more patterns. F# 4.7 is included, and focused on relaxing syntax and targeting .NET Standard 2.0.
