Pull request overview

This PR adds an AGENTS.md file to document recent software releases that AI models may not be aware of, given their training cutoff dates. The file lists .NET 10, Visual Studio 2026, and C# 14 with references to their official documentation, and is configured to be excluded from the published documentation build.

• Adds new AGENTS.md file with release information for .NET 10, Visual Studio 2026, and C# 14
• Configures docfx.json to exclude AGENTS.md from documentation builds

This LGTM, but we have to figure out how to get it past the OPS build

Also I think CleanRepo will pick it up as an orphaned file. Can it not live in the .github folder?

Hrmmm. Well I was trying to avoid moving it up to the root of the repo, but that is an option. The docfx should have excluded it from building but perhaps I got that setting incorrect.

I was thinking of trying to do a glob to exclude any file named agents.md but then I discovered there is docs\ai\conceptual\agents.md. That file might mess up copilot if you use it in that folder.

It looked like the docfx exclusion was correct. I didn't see anything wrong.
