Start To Finish C# .NET API + React App + SQL [w/ Docker Deployment & Provisioning]

This video focuses on setting up a full‑stack application using .NET 9 Web API, React, and PostgreSQL, with Docker deployment to Fly.io. It covers project structure, database provisioning and schema creation, C# code scaffolding, configuration via the Options pattern, secure secret handling, and API setup. The minimal client demonstrates API behavior, including CORS configuration, controller methods, DTOs, Swagger documentation, data validation, exception handling, and service refactoring. It also shows generating a TypeScript HTTP client from the OpenAPI spec with NSwag and using it to request the API, culminating in adding a new "Done" feature for todos.
