@copilot This is great, based on my original prompt. I think it makes sense to expand this PR to handle the following additional tasks from #56738:

• Update support tables - e.g. https://learn.microsoft.com/en-us/dotnet/core/install/windows?tabs=net60#supported-releases
• Update .NET Standard support tables - https://learn.microsoft.com/en-us/dotnet/standard/net-standard
• Update the recommended target framework versions in the Open-source library guidance
• Remove versions that've gone out of support (.NET 8 and 9 - November 10, 2026)

I'll review again when you've made those additional changes.

Expanded the PR as requested in commit 5cb346ac. Updated the OS support matrices, .NET Standard compatibility tables, recommended library TFMs, and current lifecycle examples. .NET 8/9 remain only in historical compatibility and package-availability references. Markdownlint, diff checks, and secret scanning passed.

This is now ready.

@copilot You added the definition for the dotnet-11 zone pivot, but it's not in use. We need to either remove the definition, or add zones where appropriate so that it is used. Determine which based on the changes in this PR. If the PR grows too large, remove the pivot definition. If it's only a few files, add it to this PR.

Added .NET 11 pivot zones to the Docker build tutorial and Newtonsoft.Json migration guide in commit e59cd027. Both articles already used the .NET version pivot, so the definition is now in use. Markdown lint, pivot YAML parsing, diff checks, and secret scanning passed.
