.NET version support policy update

Hey folks.

This announcement is long overdue. As of April 30, we will no longer ship builds that target framework versions <= 5.0 & > 8.0. These target framework versions have been EOL for quite some time and we need to move on.

Starting in May 2026 we be building with the following target frameworks:

• netstandard2.0
• netstandard2.1
• net8.0
• net10.0

The net targets will only be for LTS versions follow the support lifecycle for .NET as a whole as listed here https://dotnet.microsoft.com/en-us/platform/support/policy/dotnet-core, i.e. after November 2026 we will drop net8.0 and then add net12.0 when it becomes GA.

.NET Framework support will be provided via the netstandard2.0 target
EOL versions of .NET will not have explicit support but should be able to consume the netstandard2.1 target publish.

The releases in May will have new major version numbers to reflect the fact that folks using some older .NET versions may experience difficulty and should really upgrade to supported .NET versions.

This announcement also applies the beta and core packages that we provide.

No files, tests, or entry points are named. Start by reviewing the stated target-framework policy alongside the repository's package and build configuration; done means the May 2026 targets, package coverage, and .NET support lifecycle are documented and aligned.
