## What it does

This skill provides workflow patterns and rules for .NET continuous integration. It constructs pipelines for GitHub Actions and Azure DevOps, covering dependency restoration, Release builds, formatting checks with `dotnet format --verify-no-changes`, and test execution with TRX artifact reporting. In GitHub Actions workflows, it also configures a PostgreSQL 18 service container for integration tests.

The skill enforces building a single artifact that promotes across environments instead of compiling separate configurations for staging and production. It includes workflows for packaging and pushing libraries to NuGet via `dotnet nuget push`, as well as publishing Docker images to GitHub Container Registry (`ghcr.io`) triggered by Git version tags.

Plaintext secrets inside workflow YAML are explicitly flagged as bad practice. When targeting Azure DevOps instead of GitHub Actions, service containers require separate Docker tasks or pipeline service connections rather than a simple `services` block.

## Requirements
- Works with: Azure DevOps

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add codewithmukesh/dotnet-claude-kit --skill ci-cd -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/ci-cd/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/ci-cd/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add codewithmukesh/dotnet-claude-kit --skill ci-cd -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/ci-cd/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add codewithmukesh/dotnet-claude-kit --skill ci-cd -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/ci-cd/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install codewithmukesh/dotnet-claude-kit ci-cd
```

2. **Manually: put the files in place**
- File: `.github/skills/ci-cd/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add codewithmukesh/dotnet-claude-kit --skill ci-cd -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/codewithmukesh/dotnet-claude-kit --path skills/ci-cd
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/ci-cd/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add codewithmukesh/dotnet-claude-kit --skill ci-cd -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/codewithmukesh/dotnet-claude-kit/tree/HEAD/skills/ci-cd/SKILL.md

## When to use it
- configure GitHub Actions workflows for .NET builds and tests
- set up Azure DevOps pipelines with dotnet format checks
- publish versioned Docker images to GitHub Container Registry
- pack and release libraries to the NuGet gallery

## Example prompts
- Create a GitHub Actions CI pipeline for a .NET 10 web app with PostgreSQL tests
- Set up an Azure DevOps YAML pipeline that builds and tests our .NET solution
- Write a workflow to pack and push my library to NuGet on tag push

  CI/CD pipelines for .NET applications. Covers GitHub Actions and Azure DevOps
  YAML pipelines with build, test, publish, and deploy stages.

# CI/CD

## Core Principles

1. **Pipeline as code** — YAML pipelines committed to the repo. No click-ops in the UI.
2. **Fast feedback** — Build and test on every push. Cache NuGet packages. Fail fast.
3. **Build once, deploy many** — Build the artifact once, promote it through environments (dev → staging → production).
4. **Never skip tests** — Tests gate the pipeline. No deployment without passing tests.

## Patterns

### GitHub Actions — Build + Test

```yaml
# .github/workflows/ci.yml
name: CI

on:
  push:
    branches: [main]
  pull_request:
    branches: [main]

env:
  DOTNET_VERSION: '10.0.x'
  DOTNET_NOLOGO: true
  DOTNET_CLI_TELEMETRY_OPTOUT: true

jobs:
  build-and-test:
    runs-on: ubuntu-latest

    services:
      postgres:
        image: postgres:18
        env:
          POSTGRES_DB: testdb
          POSTGRES_USER: postgres
          POSTGRES_PASSWORD: postgres
        ports:
          - 5432:5432
        options: >-
          --health-cmd pg_isready
          --health-interval 10s
          --health-timeout 5s
          --health-retries 5

    steps:
      - uses: actions/checkout@v5

      - name: Setup .NET
        uses: actions/setup-dotnet@v5
        with:
          dotnet-version: ${{ env.DOTNET_VERSION }}

      - name: Restore
        run: dotnet restore

      - name: Build
        run: dotnet build --no-restore --configuration Release

      - name: Format check
        run: dotnet format --verify-no-changes --no-restore

      - name: Test
        run: dotnet test --no-build --configuration Release --logger trx --results-directory TestResults
        env:
          ConnectionStrings__Default: "Host=localhost;Database=testdb;Username=postgres;Password=postgres"

      - name: Publish test results
        uses: actions/upload-artifact@v5
        if: always()
        with:
          name: test-results
          path: TestResults/*.trx
```

### GitHub Actions — Build + Publish Docker Image

```yaml
# .github/workflows/publish.yml
name: Publish

on:
  push:
    tags: ['v*']

jobs:
  publish:
    runs-on: ubuntu-latest
    permissions:
      contents: read
      packages: write

    steps:
      - uses: actions/checkout@v5

      - name: Login to GitHub Container Registry
