.NET 8 LTS Released With Integratable Large Language Models; Fastest .NET To Date

NET 8 ReleasedNET 8 Released

For the .NET developers, the moment you have been waiting for is finally here. Microsoft has released .NET 8, which is the Long Term Service (LTS) version, in line to replace .NET 6. .NET is planned to have 3 years of active support from its release date , which is 14th November 2023.

This release also introduces F# 8, C# 12, and .NET MAU in .NET 8. This post provides the direct download links for the .NET 8 SDKs, Runtimes, and ASP.NET Core libraries and also discusses the major features.NET 8, so that you can make an informed decision on whether and when to upgrade your production environments.

What’s new in .NET 8

Integrate Large Language Models (LLMs)

Developers will now be able to integrate LLMs into their applications, like GPT4 and Bard. This will allow the developers to bring the touch of Artificial Intelligence (AI) to their applications and significantly enhance their performance, as well as user experience.

New code generator

Microsoft has included a new code generator called Dynamic Profile-Guided Optimization (PGO), which drastically improves the speed of .NET 8. It optimizes your code based on real-world usage which is enabled by default and can improve the performance of your apps by up to 20%.

Additionally, the AVX-512 instruction set, which is now supported, enables you to perform parallel operations on 512-bit vectors of data, meaning you can process much more data in less time.

.NET Aspire

.NET Aspire is a stack for building resilient, observable, and configurable cloud-native applications with .NET. It includes a set of components enhanced for cloud-native applications by including telemetry, resilience, configuration, and health checks by default.

Combined with a sophisticated but simple local developer experience, .NET Aspire makes it easy to discover, acquire, and configure essential dependencies for cloud-native applications on day 1 as well as day 100.

Note that this feature is still in its preview state, so expect room for further improvements.

Container enhancements

The containers have now been made more secure than ever in .NET 8. Every .NET image includes a non-root user, enabling more secure containers with one-line configuration.

You can also choose to harden the security further with the new Chiseled Ubuntu image variants to reduce your attack surface even further. Using Dockerfiles or SDK tooling, build apps and container images for any architecture.

Native Ahead-of-Time (AOT) compiler

Instead of using Just-in-Time compilers, .NET now uses an AOT compiler, which enhances .NET’s performance. You no longer need to deploy the JIT compiler and IL code. AOT apps deploy just the code that’s needed for your app. The application is now empowered to run in restricted environments where a JIT compiler isn’t allowed.
