Windows 10: .NET Core August 2018 Update now released

Brink · Aug 21, 2018

Today, we are releasing the .NET Core August 2018 Update. This update includes .NET Core 2.1.3 and .NET Core SDK 2.1.401.

Getting the Update

The latest .NET Core updates are available on the .NET Core download page.

See the .NET Core 2.1.3 release notes for details on the release including a detailed commit list.

Docker Images

.NET Docker images have been updated for today’s release. The following repos have been updated.

microsoft/dotnet
microsoft/dotnet-samples

Note: Look at the “Tags” view in each repository to see the updated Docker image tags.

Note: You must re-pull base images in order to get updates. The Docker client does not pull updates automatically.

2.1 declared LTS

As mentioned in a previous blog post, we have been working toward declaring .NET Core 2.1 as LTS. With the August Update, we’re pleased to announce that 2.1.3 begins the .NET Core 2.1 LTS lifecycle. We’ll continue to update 2.1 with important fixes to address security and reliability issues as wells as add support for new operating system versions. Details on the .NET Core lifecycle can be seen in the .NET Core support policy.

What’s covered?

The LTS designation covers all packages referenced by Microsoft.NETCore.App and Microsoft.AspNetCore.App. To ensure that applications running on 2.1 remain on the LTS supported updates, it’s important to reference these ‘meta-packages’ rather than individual ‘loose’ packages. This will enable the applications to properly utilize 2.1 updates when they are released and installed.

The .NET Core SDK is not included as part of the LTS designation. SDK fixes will continue to be released in the latest version ‘train’ which supports maintaining and building applications for .NET Core 2.1.

See .NET Core Supported OS Lifecycle Policy to learn about Windows, macOS and Linux versions that are supported for each .NET Core release.

.NET Core January 2018 Update

Today, we are releasing the .NET Core January 2018 Update. This includes .NET Core 1.0.9, 1.1.6 and 2.0.5.

Please leave feedback on the release in the comments below or at dotnet/core #1199.

Security

CVE-2018-0786 – Security Feature Bypass in X509 Certificate Validation

Microsoft is aware of a security vulnerability in the public versions of .NET Core where an attacker could present a certificate that is marked invalid for a specific use, but a component uses it for that purpose. This action disregards the Enhanced Key Usage tagging.

The security update addresses the vulnerability by ensuring that .NET Core components completely validate certificates.

CVE-2018-0786

CVE-2018-0764 – Denial of Service when parsing XML documents

Microsoft is aware of a Denial of Service vulnerability in all public versions of .NET core due to improper processing of XML documents. An attacker who successfully exploited this vulnerability could cause a denial of service against a .NET application. A remote unauthenticated attacker could exploit this vulnerability by issuing specially crafted requests to a .NET Core application.

The update addresses the vulnerability by correcting how .NET core handles XML document processing.

CVE-2018-0764

Getting the Update

The .NET Core January 2017 Update is available from the .NET Core download page.

You can always download the latest version of .NET Core at .NET Downloads.

Docker Images

.NET Docker images have been updated for today’s release. The following repos have been updated.

microsoft/dotnet

microsoft/dotnet-samples

microsoft/aspnetcore/

microsoft/aspnetcore-build/

Note: Look at the “Tags” view in each repository to see the updated Docker image tags.

Announcing .NET Core 2.1

We’re excited to announce the release of .NET Core 2.1. It includes improvements to performance, to the runtime and tools. It also includes a new way to deploy tools as NuGet packages. We’ve added a new primitive type called Span<T> that operates on data without allocations. There are many other new APIs, focused on cryptography, compression, and Windows compatibility. It is the first release to support Alpine Linux and ARM32 chips. You can start updating existing projects to target .NET Core 2.1 today. The release is compatible with .NET Core 2.0, making updating easy.

ASP.NET Core 2.1 and Entity Framework Core 2.1 are also releasing today.

You can download and get started with .NET Core 2.1, on Windows, macOS, and Linux:

.NET Core 2.1 SDK (includes the runtime)

.NET Core 2.1 Runtime

.NET Core 2.1 is supported by Visual Studio 15.7, Visual Studio for Mac and Visual Studio Code.

Docker images are available at microsoft/dotnet for .NET Core and ASP.NET Core.

The Build 2018 conference was earlier this month. We had several in-depth presentations on .NET Core. Check out Build 2018 sessions for .NET on Channel9.

You can see complete details of the release in the .NET Core 2.1 release notes. Related instructions, known issues, and workarounds are included in the releases notes. Please report any issues you find in the comments or at dotnet/core #1614

Thanks for everyone that contributed to .NET Core 2.1. You’ve helped make .NET Core a better product!

Announcing .NET Core, .NET Native and NuGet Updates in VS 2017 RC

We just released updates to the .NET Core SDK, .NET Native Tools and NuGet, all of which are included in Visual Studio 2017 RC. You can also install the .NET Core SDK for command-line use, on Windows, Mac and Linux. Please check out the ASP.NET blog to learn more about Web Tools updates and the Visual Studio blog for the Visual Studio 2017 RC update.

Install Visual Studio 2017 RC

Install .NET Core 1.0 SDK – RC3

The following improvements are the .NET highlights of the release:

.NET Core – The csproj project format has been simplified and project migration is much more reliable.

.NET Native – Major performance increase for SIMD and other performance improvements.

NuGet – .NET Framework, UWP, .NET Core and other .NET projects can now use PackageReference instead of packages.config for NuGet dependencies.

Note: csproj projects created with earlier releases of Visual Studio 2017 or on the command-line with the .NET Core SDK must be manually updated to load in the latest release. Please read the Updating .NET Core Projects section, below, for more information.

.NET Core

The .NET Core tools have been significantly improved in this update, fixing bugs and usability issues. A major focus of this release has been simplifying the project file and improving project migration. We are no longer using the “preview” term, but “RC3” to match Visual Studio 2017 RC.

The tools in the new SDK produce and operate on csproj projects. If you are using project.json projects, including with Visual Studio 2015, then please wait to install the new SDK until you are ready to move to csproj and MSBuild. If you are a Visual Studio user, you will get the SDK when you install Visual Studio 2017. See Known issues for Web Tools, and ASP.NET and ASP.NET/.NET Core in Visual Studio 2017.

Getting the Release

This .NET Core SDK release is available in Visual Studio 2017 RC, as part of the .NET Core cross-platform development workload. It is also available in the ASP.NET Web workload and an optional component of the .NET Desktop workload. These workloads can be selected as part of the Visual Studio 2017 RC installation process. The ability to build and consume .NET Standard class libraries is available in the all of the above workloads and in the UWP workload.

You can also install the .NET Core SDK release for command-line use on Windows, macOS and Linux by following the instructions at .NET Core 1.0 – RC3 Download.

The release is also available as Docker images, in the dotnet repo. The following images include the new SDK:

1.0.3-sdk-msbuild-rc3

1.0.3-sdk-msbuild-rc3-nanoserver

1.1.0-sdk-msbuild-rc3

1.1.0-sdk-msbuild-rc3-nanoserver

The aspnetcore-build repo has also been updated.

.NET Core SDK Components

This release contains the .NET Core Tools 1.0 RC3, the .NET Core 1.0.3 runtime and the .NET Core 1.1.0 runtime. No changes have been made to the .NET Core runtime in this release. .NET Core 1.0.3 and 1.1.0 were both released previously.

The .NET Core SDK includes a set of .NET Core Tools and one of more runtimes. In previous SDK releases, there was only ever one runtime included. This change in approach was made to make it easier to acquire all supported runtimes as a single step. This experience helps when you are collaborating with developers who are using multipe runtimes. It also makes it easier to update multiple runtimes on your machine when fixes are released. The SDK naturally gets larger, but not as much as you might guess since there is only ever one set of tools in the package. It also enables us to improve the tools for everyone more easily...
