Azure App Service CI/CD with GitHub Actions

Draw an ASCII architecture diagram that traces code, credentials, build output, and deployment from GitHub to Azure App Service.

Create and locally verify a minimal ASP.NET Core .NET 10 web application suitable for a live deployment demonstration.

Configure a Linux Azure App Service target for the .NET 10 demonstration application and verify its baseline state.

Create a least-privileged Azure service principal with a client secret, store its credentials in GitHub Secrets, and explain rotation and exposure risks.

Author a GitHub Actions continuous-integration job that checks out, restores, builds, tests, and publishes the ASP.NET Core application.

Author a dependent deployment job that signs in to Azure with the service principal and deploys the published application to Azure App Service.

Walk through the complete workflow YAML line by line, relating each directive to the execution flow and architecture diagram.

Rehearse an end-to-end live demo that triggers the workflow, follows its logs, and validates the deployed application.

Diagnose common trigger, YAML, runner, build, secret, authentication, runtime, and deployment failures using GitHub Actions and App Service evidence.

Compare service-principal client-secret authentication with Publish Profile authentication, and explain why OpenID Connect is the preferred future upgrade.

Explain how deployment slots support pre-production validation, traffic-safe swaps, and rollback.

Explain how GitHub Environments, protection rules, and required approvals add deployment governance.

Assemble a presentation-ready workshop package containing ordered slides, realistic timings, talking points, speaker notes, demo instructions, ASCII diagrams, key takeaways, interview questions and answers, a fallback demo plan, and an advanced roadmap covering reusable workflows and Infrastructure as Code.
