Overview

Official .NET team marketplace of agent skills, grouped into 16 plugins covering MSBuild, NuGet, EF data access, testing, upgrades, ASP.NET Core, Blazor, MAUI, WinForms and .NET AI. It installs through the plugin marketplaces of Copilot CLI, Claude Code, VS Code, Cursor and Codex CLI. It also ships GitHub Copilot custom agents and GitHub Agentic Workflows.

Who it is for: .NET developers using coding agents like Copilot, Claude Code, Cursor or Codex

Strengths

Maintained by the .NET team, with 16 plugins split by area (MSBuild, NuGet, EF, Blazor, MAUI)
Installs via marketplace in Copilot CLI, Claude Code, VS Code, Cursor and Codex CLI
Public dashboard reports token use, elapsed time and activation rates per skill
Skills follow the agentskills.io open standard, so they port across hosts

Weaknesses

Custom agents (*.agent.md) use Copilot conventions and are not installed as native Codex agents
VS Code plugin support is a preview feature and may change
No native Codex agent files (.codex/agents/*.toml) are shipped
Only useful for .NET work

What it needs

no GPU
Needs Copilot CLI, Claude Code, VS Code, Cursor or Codex CLI (v0.121.0+ for plugin marketplace)

How to choose

Check which agent it targets and whether it works with the version you run.
Read what it adds to every prompt; big rule sets cost tokens on each call.
Prefer add-ons you can turn off per project.
