What’s new in .NET 6?

New features in .NET 6

.NET 6 was released on November 8 2021. Dot NET 6 conveys the latest pieces of the .NET unification plan that began with .NET 5. Dot NET 6 brings together the SDK, base libraries, and runtime across mobile devices, desktop, IoT, gaming and cloud applications. Notwithstanding this unification, the .NET 6 environment offers:-

  1. Ease of Development: Getting begun is simple. New dialect includes in C# 10 diminish the measure of code you really want to compose. Furthermore, interests in the web stack and insignificant APIs make it simple to rapidly compose more modest, quicker microservices.
  2. Improved Performance: Dot NET 6.0 is the quickest full stack web framework, which brings down figure costs in the event that you’re running in the cloud.

.NET 6 will be supported for a considerable duration of time as a Long Term Support (LTS).

This version is upheld by Visual Studio 2022 and Visual Studio 2022 for Mac (and later versions).

.NET 6 Key Feature Highlights

  1. Production stress-tested with Microsoft services, cloud apps run by other companies, and open source projects.
  2. Supported for three years as the latest long term support (LTS) release.
  3. Unified platform across browser, cloud, desktop, IoT, and mobile apps, all using the same .NET Libraries and the ability to share code easily.
  4. Performance is greatly improved across the board and for file I/O in particular, which together result in decreased execution time, latency, and memory use.
  5. C# 10 offers language improvements such as record structs, implicit using, and new lambda capabilities, while the compiler adds incremental source generators. F# 6 adds new features including Task based async, pipeline debugging and numerous performance improvements.
  6. Visual Basic has improvements in the Visual Studio experience and for Windows Forms project open experience.
  7. Hot Reload 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.
  8. Cloud diagnostics have been improved with Open Telemetry and dotnet monitor, which is now supported in production and available with Azure App Service.
  9. JSON APIs are more capable and have higher performance with a source generator for the serializer.
  10. Minimal APIs introduced in ASP.NET Core to simplify the getting started experience and improve the performance of HTTP services.
  11. Blazor components can now be rendered from JavaScript and integrated with existing JavaScript based apps.
  12. WebAssembly AOT compilation for Blazor Web Assembly (Wasm) apps, as well as support for runtime relinking and native dependencies.
  13. Single-page apps built with ASP.NET Core now use a more flexible pattern that can be used with Angular, React, and other popular frontend JavaScript frameworks.
  14. HTTP/3 has been added so that ASP.NET Core, HttpClient, and gRPC can all interact with HTTP/3 clients and servers.
  15. File IO now has support for symbolic links and has greatly improved performance with a re-written-from-scratch FileStream.
  16. Security has been improved with support for OpenSSL 3, the ChaCha20Poly1305 encryption scheme, and runtime defense-in-depth mitigations, specifically W^X and CET.
  17. Single-file apps (extraction-free) can be published for Linux, macOS, and Windows (previously only Linux).
  18. IL trimming is now more capable and effective, with new warnings and analyzers to ensure correct final results.
  19. Source generators and analyzers have been added that help you produce better, safer, and higher performance code.
  20. Source build enables organizations like Red Hat to build .NET from source and offer their own builds to their users.
