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
