Discover why minimal APIs lower entry barriers for beginners, reduce boilerplate, and enable quick, dependency-light web services ideal for microservices and rapid proofs of concept.

Learn how to use the map methods in a minimal api to expose routes like get, post, delete, and put, with inline or external delegates.

Discover how to expose a courses endpoint with Minimal API, build an in-memory collection and data model, and implement the get operation to fetch all courses with dependency injection.

Implement a get operation in a minimal API to fetch all items by injecting the database context into the map get method, retrieving the course list from the in-memory store.

Discover how minimal API returns results with the IResult contract and the Results factory, using status helpers like ok, not found, bad request, and no content.

update the get operation to use results, store in a temporary variable, then return the result with http 200, and demonstrate handling 400 bad requests via postman.

Learn how to convert map get operations to asynchronous processing using async/await to return results without blocking, improving performance for web apps and enterprise applications.

Implement the post operation to add a new course using map post, with dependency injection for the database context, save changes, and return a created response containing the new course.

Step 11 introduces digital models (input DTOs) to replace data models for post and get operations, exposing a subset of properties and reducing payload size.

Learn how to use AutoMapper to map between data models and input models in a .NET minimal API, configure profiles, register services, and streamline map operations.

Apply AutoMapper in map post method by injecting the mapper, convert the input model to the data model, persist with EF, then map back and ensure enum values are strings.

Implement the get operation to fetch a single item by its id using routing /courses/{id}, validate existence, map the data model, and return the result or not found.
