.NET Core 3 Released

Spread the love

As you might know .NET Core 3 was released a couple of days ago and it came with some exciting features including adding Windows Forms and WPF, new JSON APIs, support for ARM64 and improving performance. C# 8 is also part of this release, which includes nullable, async streams, and more patterns. F# 4.7 is included and you can start updating existing projects to target .NET Core 3.0 today since there is backwards compatibility.

You can download .NET Core 3.0, for Windows, macOS, and Linux:

  • Windows Desktop apps are now supported with .NET Core, for both Windows Forms and WPF (and open source).
  • .NET Core apps now have executables by default.
  • High performance JSON APIs have been added, for reader/writer, object model and serialization scenarios.
  • The garbage collector uses less memory by default, often a lot less.
