NServiceBus 8.2

Apply the C# 14 prompt first. These rules cover NServiceBus core 8.2, including its built-in DataBus. Select extension packages compatible with core 8; the Json.NET and Transactional Session APIs below refer to their 3.x and 2.x lines respectively.

Extended-support and runtime constraints

• Lock NServiceBus to the newest 8.2 patch available to you through Central Package Management or a lock file. Particular supports only the latest patch of a supported minor line and fixes vulnerable dependencies by shipping new core and component patches, each versioned separately, so a patched core doesn't prove the complete deployed application is free of vulnerable dependencies.
• Keep the baseline's NuGet audit covering the whole resolved application graph, including hosting and diagnostic tools; assess advisory applicability and remediate affected dependencies instead of suppressing warnings.
• Pin compatible transport, persistence, serializer, hosting, and monitoring packages separately because component support windows can be shorter than NServiceBus core support.
• Treat 8.2 as legacy: mainstream support ended 2026-04-16. Paid extended support ends 2028-04-16 for modern .NET systems and 2031-04-16 for .NET Framework systems; critical patches during extended support require an appropriate Particular agreement.
• Account for the package targets net6.0 and net472: core 8 runs on .NET 6+ or .NET Framework 4.7.2+, but production requires a Microsoft-supported runtime and operating system. Prefer a tested .NET 10 host for the C# 14 baseline; do not assume its newer runtime
