Microsoft 公布 .NET 5.0 RC2

Microsoft has released RC 2 of the much anticipated .NET 5.0. This is a "go live" release and you are supported using it in production, so you can start using .NET 5.0 in production NOW!

They also released new versions of ASP.NET Core and EF Core.

Please note: You need the latest preview version of Visual Studio (including Visual Studio for Mac) to use .NET 5.0.

.NET 5.0 includes many improvements, notably single file applications, smaller container images, more capable JsonSerializer APIs, a complete set of nullable reference type annotations, new target framework names, and support for Windows ARM64. Performance has been greatly improved, in the .NET libraries, in the GC, and the JIT. ARM64 was a key focus for performance investment, resulting in much better throughput and smaller binaries. .NET 5.0 includes new language versions, C# 9 and F# 5.0.
