.NET Core 3.1.8 is available for download and usage in your environment. This release includes .NET Core 3.1.8 and .NET Core SDK 3.1.108.
The .NET Core SDK 3.1.108 includes .NET Core 3.1 Runtime so downloading the runtime packages separately is not needed when installing the SDK. After installing the .NET Core SDK 3.1.108, the following command will show that you’re running version 3.1.108 of the tools.
dotnet --version
Your feedback is important and appreciated. We’ve created an issue at dotnet/core #5170 for your questions and comments.

Visual Studio compatibility: .NET Core 3.1 requires Visual Studio 2019 16.4 or above to take full advantage of all its features. .NET Core 3.1 won’t work properly in earlier versions of Visual Studio. See the following table to select the correct download.
| OS | Development Environment | .NET Core SDK |
|---|---|---|
| Windows | Visual Studio 2019 version 16.7 | 3.1.402 |
| Windows | Visual Studio 2019 version 16.4 | 3.1.108 |

The .NET Core Docker images have been updated for this release. Details on our Docker versioning and how to work with the images can be seen in “Staying up-to-date with .NET Container Images”.
The following repos have been updated
.NET Core 3.1.8 release carries both security and non-security fixes.
Microsoft is releasing this security advisory to provide information about a vulnerability in ASP.NET Core. This advisory also provides guidance on what developers can do to update their applications to remove this vulnerability.
A security feature bypass vulnerability exists in the way Microsoft ASP.NET Core parses encoded cookie names.
The ASP.NET Core cookie parser decodes the cookie name which could allow a malicious attacker to use percent encoded characters to masquerade as a different cookie with different security features.
The security update addresses the vulnerability by fixing the way the ASP.NET Core cookie parser handles encoded names.
Running “dotnet build” will generate a dll instead of a dylib on macOS. This is a planned change to not use the AppHost by default on macOS because of notarization requirements. If you want to opt into using the AppHost, please use following:

<UseAppHost>true</UseAppHost>
