Aimed at unifying the .NET platform, .NET 5 brings improvements to RyuJIT code quality, garbage collection, and JSON serialization, for starters

What’s new in Microsoft .NET 5

Microsoft has published a sixth preview of .NET 5. Preview 6 removes WinRT support, adds support for Windows Forms on Windows ARM64 devices, and continues to extend RyuJIT code quality improvements.

Microsoft has said that .NET 5 would be feature-complete by Preview 7. .NET 5 is a merger of .NET Framework and .NET Core that is intended to unify the .NET platform. The new platform is due for general availability November 10, 2020.

High-level goals for .NET 5 include providing a unified .NET SDK experience, with a single BCL (base class library) across all .NET 5 applications, and with support for both native and web applications across multiple operating systems. A single .NET 5 native application project would support targets such as Windows, Microsoft Duo (Android), and Apple iOS using native controls on those platforms.
