.NET 6 Release Candidate 1 (RC1) is now available and includes many great new improvements to ASP.NET Core. 

Porting existing code to .NET Core used to be quite hard because the available API set was very small. In .NET Core 2.0, we already made this much easier, thanks to .NET Standard 2.0. Today, we’re happy to announce that we made it even easier with the Windows Compatibility Pack, which provides access to an additional 20,000 APIs via a single NuGet package. 

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. You can start updating existing projects to target .NET Core 3.0 today. The release is compatible with previous versions, making updating easy.
