NET 8 RC 2NET 8 RC 2

Microsoft has now released .NET 8 Release Candidate (RC) 2. This is the second of the two release candidates that were to be made available before the actual release of .NET 8 stable on .NET Conf 2023 to be held on 14-16th November 2023.

With this release, major improvements have been announced for ASP.NET Core.NET MAUI, and Entity Framework Core included in .NET 8 RC 2.

Let us continue to see the new improvements in this release before continuing to download it.

New in .NET 8 Release Candidate 2

New package READMEs for .NET Libraries

Microsoft is now adopting an increase in documentation as well as the quality of NuGet package READMEs.

READMEs are an essential part of the package as they provide important information to users and help them understand what the package is and what it does quickly. Also, READMEs are the first things for users when they view the package on NuGet.org and soon other tooling.

Package authors must write and include high-quality READMEs in their packages.

You can find a complete list of Microsoft packages with READMEs here.

SDK Container Publish: Publish to tar.gz archive

Users now can create a container directly as a tar.gz archive.

Previously, SDK has been able to publish containers to local container tools like Docker and Podman, as well as Remote Container Registries like Azure Container Registry, Amazon’s Elastic Container Registry, and Docker Hub. However, not all workflows are so straightforward. Some may prefer to run scanning tools over their images before pushing them.

To smoothen these workflows, you can now create a container directly as a tar.gz archive. Here is how one of the community members of .NET achieved this functionality:

>dotnet publish -p PublishProfile=DefaultContainer -p ContainerArchiveOutputPath=./images/sdk-container-demo.tar.gz

  Pushed image 'sdk-container-demo:latest' to local archive at 'D:\code\sdk-container-demo\src\sdk-container-demo\images\sdk-container-demo.tar.gz'.

Tensor Primitives for .NET

Tensor Primitives is the next step in the evolution of Numerics for AI in .NET by building on top of hardware intrinsics and Generic Math, and this set of features is included in .NET 8 starting with RC2.

Tensor Primitives is short for System.Numerics.Tensors.TensorPrimitives, a new set of APIs that introduce support for tensor operations. The TensorPrimitives APIs are delivered through a standalone System.Numerics.Tensors NuGet package. The contents of this package supplant the previous System.Numerics.Tensors package.

Ending thoughts

.NET 8 will replace .NET 6 in the Long Term Support (LTS) channel which is said to be supported for 3 years after its initial release. Currently, its preview version is available to download which is now Release Candidate. Note that this is the final Release Candidate or preview release for .NET 8. Next, only the stable release will be made.

That said, we suggest that you remain on the stable releases for your production environment while continuing to test out the latest features and improvements in an isolated environment within .NET 8.
