.NET 7 officially released

Produced | OSC Open Source Community (ID: oschina2013)

Microsoft has announced the general availability of .NET 7, which makes it easy to containerize .NET 7 projects, set up CI/CD workflows in GitHub Actions, and achieve cloud-native observability.

.NET 7 is the Standard Term Support (STS) release and will be supported for 18 months. Over 8900 contributors made 28k code contributions throughout the .NET 7 release.

Optimizations in .NET 7 focus on:

A Base Class Library (BCL)

With .NET 7, you can build multiple types of applications (cloud, web, desktop, mobile, gaming, IoT, and AI) iteratively with one SDK, one runtime, one set of foundational libraries, and one SDK.

Native support for ARM64

Optimized performance on Arm machines, including estimating L3 cache size, introducing LSE atomic instructions, optimizing libraries using intrinsics.

Enhanced .NET support on Linux

.NET 6 is included in Ubuntu 22.04 (Jammy) and can be installed using the apt install dotnet6 command. Additionally, there is an optimized, pre-built, out-of-the-box ultra-small container image.

64-bit IBM Power support

In addition to x64 architectures (64-bit Intel/AMD), ARM64 (64-bit ARM), and s390x (64-bit IBM Z), .NET is also available for RHEL’s ppc64le (64-bit IBM Power) architecture 8.7 and RHEL 9.1.

NET MAUI

NET MAUI is already part of .NET 7 with numerous improvements and new features. Check out the .NET MAUI status (https://ift.tt/ZRPfqij) and project roadmap (https://ift.tt/6JuzX21) for more information.

modernization

The .NET SDK supports output container images, for more information on built-in container support, see Built-in container support for the .NET SDK: https://ift.tt/A3xctf9

Upgrade Assistant

The .NET Upgrade Assistant includes more analyzers, code fixes, and upgrade support for more application types, making it easier for developers to upgrade their .NET 7 application portfolio and less effort to upgrade applications.

.NET Cloud Native

.NET 7 makes it easier to build and deploy distributed cloud-native applications.

performance

.NET 7 has several performance optimizations such as:

• On Stack Replacement (OSR), improved startup time.

• Profile-Guided Optimization (PGO)

• Native AOT, the main advantages are boot time, memory usage, access to restricted platforms (no JIT allowed) and less disk space.
