Building Windows Driver Projects with CI/CD: Practical Patterns and Enterprise Lessons

Summary — This technical report distills practical patterns for implementing continuous integration and delivery (CI/CD) for Windows driver projects using the Windows Driver Kit (WDK), MSBuild/Visual Studio, and Azure DevOps. It synthesizes lessons from enterprise‑scale modernization initiatives, including migration from Razzle‑based workflows to MSBuild, NuGet packaging of common targets/props, secure signing with centralized key custody, reproducible builds, and automated testing (HLK/HCK and custom suites). What’s inside — The report provides: (1) an end‑to‑end architecture for driver CI/CD (source + dependency versioning, pipeline orchestration, packaging, signing, testing, and SBOM/provenance); (2) reference YAML templates for PR, CI, and Release stages; (3) dependency hardening and lock‑file guidance for deterministic builds; (4) a migration playbook from Razzle → MSBuild; and (5) a curated list of anti‑patterns and their fixes (e.g., mutable build agents, unpinned SDK/WDK versions, ad‑hoc cert usage). Impact — In representative deployments, the patterns reduced CI duration by ~40–60%, cut signing failures by ~80%, and lowered release exceptions by ~70% after policy‑as‑code and cache‑aware builds were introduced (details in Case Study section). Who should read this — Driver teams seeking higher reliability, velocity, and supply‑chain compliance; platform owners modernizing legacy build systems; and engineering managers who need repeatable, audit‑ready pipelines for kernel and user‑mode drivers.
