Microsoft’s official curriculum for .NET-savvy AI agents

What it does

The .NET team has packaged domain-specific guidance into thirteen plugins—covering everything from Entity Framework and ASP.NET Core to MSBuild diagnostics and .NET version upgrades—that AI agents consume to answer questions, scaffold code, and troubleshoot builds without hallucinating APIs that changed three releases ago.

The interesting bit

Instead of shipping a VS Code extension and calling it done, the team built against the open agentskills.io standard so the same skills load into Copilot CLI, Claude Code, Cursor, and OpenAI Codex. They even publish a live dashboard scoring accuracy and efficiency, which is more accountability than most prompt libraries bother with.

Key highlights

• Thirteen specialized plugins spanning the full stack: data access, web (Blazor/ASP.NET), mobile (MAUI), diagnostics, NuGet, testing, templates, AI/ML, and .NET 11 previews
• Cross-platform agent support: Copilot CLI/VS Code, Claude Code, Cursor marketplace, and Codex CLI via skill-installer
• Follows the open agentskills.io standard, so it isn’t locked to one vendor’s prompt format
• Public dashboard tracks accuracy and efficiency trends for the contained plugins
• Official .NET team curation, not community prompts of questionable vintage

Caveats

• VS Code integration is explicitly preview-grade and subject to change
• The README catalogs plugins and install commands but never defines what a “skill” technically contains—prompts, tool definitions, grounding documents, or something else—so the underlying format is unclear

Verdict

.NET developers who want their AI assistant to stop confidently suggesting deprecated APIs should look here. If you don’t use AI coding agents yet, this is just a well-organized table of contents.
