Best practices for Azure DevOps Pipeline YAML files

# Azure DevOps Pipeline YAML Best Practices

## General Guidelines

- Use YAML syntax consistently with proper indentation (2 spaces)
- Always include meaningful names and display names for pipelines, stages, jobs, and steps
- Implement proper error handling and conditional execution
- Use variables and parameters to make pipelines reusable and maintainable
- Follow the principle of least privilege for service connections and permissions
- Include comprehensive logging and diagnostics for troubleshooting

## Pipeline Structure

- Organize complex pipelines using stages for better visualization and control
- Use jobs to group related steps and enable parallel execution when possible
- Implement proper dependencies between stages and jobs
- Use templates for reusable pipeline components
- Keep pipeline files focused and modular - split large pipelines into multiple files

## Build Best Practices

- Use specific agent pool versions and VM images for consistency
- Cache dependencies (npm, NuGet, Maven, etc.) to improve build performance
- Implement proper artifact management with meaningful names and retention policies
- Use build variables for version numbers and build metadata
