# How would you implement CI/CD for a .NET Core project?

Implementing **CI/CD (Continuous Integration / Continuous Deployment)** for a **.NET Core project** involves automating the build, testing, and deployment process. Here's a step-by-step breakdown using modern tools like **GitHub Actions**, **Azure DevOps**, or **GitLab CI/CD**.

## Step-by-Step CI/CD Implementation for a .NET Core Project

### 1. Source Control Setup

- Use Git with GitHub, GitLab, or Azure Repos.
- Organize branches (e.g., `main`, `develop`, `feature/*`).
- Enable pull request policies (optional).

### 2. CI Pipeline – Build & Test Automation

Use a CI pipeline to:

- Restore NuGet packages
- Build the .NET solution
- Run unit tests
- Run code analysis or linting (optional)

### Example: GitHub Actions

`.github/workflows/dotnet.yml`:

```plaintext
name: Build & Test .NET Core

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

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
    - uses: actions/checkout@v3

    - name: Setup .NET
      uses: actions/setup-dotnet@v3
      with:
        dotnet-version: '7.0.x'  # or 6.0.x, etc.

    - name: Restore dependencies
      run: dotnet restore

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

    - name: Test
      run: dotnet test --no-build --verbosity normal
```

### 3. CD Pipeline – Deployment Automation

Based on environment (dev/staging/prod), deploy using:

- Azure App Service
- AWS Elastic Beanstalk / EC2
- Kubernetes (AKS/EKS)
- Docker containers

### Example: Deploy to Azure App Service

Add to GitHub workflow:

```plaintext
- name: Publish
  run: dotnet publish -c Release -o ./publish

- name: Deploy to Azure Web App
  uses: azure/webapps-deploy@v2
  with:
    app-name: 'your-app-name'
    slot-name: 'production'
    publish-profile: ${{ secrets.AZURE_WEBAPP_PUBLISH_PROFILE }}
    package: ./publish
```

### 4. Environment Management

Use **Secrets** or **Variable Groups**:

- GitHub: `Settings > Secrets and variables`
- Azure DevOps: Library → Variable Groups
- Store: DB strings, API keys, Azure publish profile

### 5. Notification and Rollback

- Add Slack/Teams/email notifications
- Enable automatic rollback on failure
- Use deployment slots (for Azure)

## Tools Comparison

| Tool | CI Support | CD Support | Hosting | Notes |
| --- | --- | --- | --- | --- |
| GitHub Actions | ✅ | ✅ | GitHub | Native to GitHub, YAML-based |
| Azure DevOps | ✅ | ✅ | Azure | Full Azure integration |
| GitLab CI | ✅ | ✅ | GitLab/GCP | Full DevOps lifecycle |
| Jenkins | ✅ | ✅ | Self-hosted | Plugin-based, flexible |

## Security Tips

- Use secret stores, never hardcode credentials
- Validate pull requests before merging
- Scan builds with tools like SonarQube or CodeQL
