For the original announcement of .NET 6, and for more detailed information, please refer to the official communication from Microsoft.
.NET 6 delivers the final parts of the .NET unification plan that started with .NET 5. .NET 6 unifies the SDK, base libraries, and runtime across mobile, desktop, IoT, and cloud apps.
.net-6.0 is the next big release to the .NET family after .NET 5.
.net-6.0 was released November 8th, 2021.
The first preview was made available on February 17th, 2021.
General Improvements :
In addition to this unification, the .NET 6 ecosystem offers:
LTS Release: .NET 6 is Supported for three years as the latest long term support (LTS) release.
Simplified development : Getting started is easy. New language features in C# 10 reduce the amount of code you need to write. And investments in the web stack and minimal APIs make it easy to quickly write smaller, faster microservices.
Better performance : .NET 6 is the fastest full stack web framework, which lowers compute costs if you're running in the cloud.
Ultimate productivity : .NET 6 and Visual Studio 2022 provide hot reload, new git tooling, intelligent code editing, robust diagnostics and testing tools, and better team collaboration.
Whats New :
C# 10 : All new C# 10 offers language improvements such as record structs, implicit using, and new lambda capabilities, while the compiler adds incremental source generators.
F# 6 : F# 6 adds new features including Task based async, pipeline debugging and numerous performance improvements.
Minimal APIs : Simplify getting started experience and HTTP services performance improvement.
Hot Reload : This feature enables you to skip rebuilding and restarting your app to view a new change — while your app is running — supported in Visual Studio 2022 and from the .NET CLI, for C# and Visual Basic.
.NET MAUI : .NET Multi-platform App UI (.NET MAUI) is still in preview, with a release candidate coming in the first quarter of 2022 and general availability (GA) in the second quarter of 2022. .NET MAUI makes it possible to build native client apps for desktop and mobile operating systems with a single codebase.
Blazor : ASP.NET Core in .NET 6 improves Blazor. Blazor components can now be rendered from JavaScript and integrated with existing JavaScript based apps.
File IO : File IO in .NET 6 has support for symbolic links and has greatly improved performance with a re-written-from-scratch
FileStream.Production stress-tested : Production stress-tested with Microsoft services, cloud apps run by other companies, and open source projects.
HTTP/3 : .NET 6 includes preview support for HTTP/3, a new version of HTTP. HTTP/3 solves some existing functional and performance challenges by using a new underlying connection protocol called QUIC. QUIC establishes connections more quickly, and connections are independent of the IP address, allowing mobile clients to roam between Wi-fi and cellular networks. For more information, see Use HTTP/3 with HttpClient.
