ASP.NET Core Minimal API Development Full Build

Install Visual Studio 2026 insiders edition and configure workloads like ASP.NET web development, MAUI, Azure. Note user interface facelift and copilot chat, and consider synchronizing settings from Visual Studio 2022.

Create a GitHub account by visiting GitHub, entering your email and password, then verifying with a code; enjoy a social-media like hub for backups, code references, and collaboration.

Download and install Postman, including the web version, to test API endpoints by sending HTTP requests and exploring verbs like get and post within a personal workspace.

Create a minimal ASP.NET Core API project in Visual Studio 2022 using the web API template with dot net seven, enable open API, and use minimal APIs without controllers.

Discover how minimal APIs replace controllers with single-file endpoints defined via map in program.cs, and document them with swagger for live testing.

Enable a cross-origin resource sharing policy by adding cors in the builder and applying a hello all policy that allows any header, origin, and method, to support third-party client integrations.

Review and update your GitHub repository for the ASP.NET Core Minimal API project by configuring source control, applying the Visual Studio gitignore, pushing private repositories, and verifying on GitHub.

Replace static sample data with real data and models, wire up a Minimal API that uses Entity Framework for database connectivity, and preview results with Swagger or Postman.

Explore option to define models in the minimal api or in a data project, create a base entity with audit fields, and model student, course, and enrollment with entity framework.

Set up entity framework in the project by adding entity framework core and tools, create a public db context with identity support, and configure the connection string in app settings.

Learn to manage database evolution with code-first migrations using entity framework core: generate and apply migrations, track changes with the migrations history, and update your database via dotnet ef commands.

Seed the database with default data for courses and roles using dedicated configurations and apply configuration; create migrations to insert administrator and user roles and initial courses.

Review and update GitHub after completing Entity Framework integration, then begin rewriting database table operations and add data driven endpoints using the default static weather forecast as a starting point.

Connect to a database, create endpoints for minimal API, inject the database into endpoints, write queries to return data, perform CRUD operations, and apply best practices for a secure API.

Explore building a minimal API with ASP.NET Core to create, read, update, and delete courses using map endpoints, a db context, and REST API design.

Configure a design-time db context factory for the student enrolment context, enabling scaffolding across multi-project setups by using environment-specific json settings and SQL Server configuration.

Scaffold endpoints for multiple tables using minimal API and entity framework, organizing with extension methods and route mappings. Enable open api swagger documentation and group endpoints in an endpoints folder.

Learn how data transfer objects (DTOs) shape API responses and requests by exposing only needed course fields such as title and credits, and using create course DTOs for safe posts.

Explore adding AutoMapper to a minimal ASP.NET Core API, configure mappings between course and course DTO, and simplify endpoint data transformations through dependency injection.

Refactor endpoints with DTO-based mapping, separating details from models, and implement course, enrollment, and student details using IMapper; anticipate repository patterns for complex queries.

Explore the repository pattern by defining a generic repository contract and its implementation, enabling CRUD operations on entities via a db context and dependency injection.

Explore implementing generic and specific repositories for a course enrollment system using EF Core, including retrieving student details with enrollments and courses, and registering services with add scoped.

Refactor enrollment endpoints to use repository pattern instead of db context, swapping to repository calls for get all, add, and delete with dependency injection. Tests and abstraction improve maintainability.

extend the minimal api with dedicated endpoints to fetch course details and enrolled students, introducing course details dto and student details dto, plus auto mapper configuration and swagger-friendly routes.

Automate endpoint creation with entity framework scaffolding, while using custom DTOs and AutoMapper to tailor responses. Build repository patterns and custom endpoints to access course and student details.

Implement user authentication and security for your api, with dot net core api tooling to restrict access to enrollments and other sensitive endpoints.

Examine methods for securing an API, from IP whitelisting and blacklisting to basic authentication, API keys, and JWT authentication. Understand how tokens support stateless requests and evaluate each method’s tradeoffs.

Extend the identity user by creating a school user class that inherits identity user, add fields like first name and last name, then update the db context and run migrations.

Add login endpoint in a minimal API by wiring an authentication endpoints class, a login dto, and user manager to verify username and password, returning 200 ok or 401 unauthorized.

Configure jwt authentication in an asp.net core minimal api by setting issuer, audience, duration, and secret key in app settings, enabling bearer authentication, and defining token validation parameters.

Implement JWT-based login with a dedicated auth manager, generate tokens using user details and claims, configure signing keys, and return an auth response DTO with user ID and token.

Develop a register endpoint that creates a user from a register DTO, using email as the username, and returns 200 on success or 400 with an error DTO on failure.

Secure your ASP.NET Core minimal API endpoints by adding authentication and authorization middleware, configuring services, and protecting routes with bearer tokens and role-based access.

Learn how to protect endpoints with selective authorization, set a global fallback policy using JWT bearer authentication, and enable anonymous access selectively in ASP.NET Core minimal API.

Explore building and securing a minimal api with jwt authentication, custom user types, role seeding, and a global authorization policy, plus a custom auth manager for login and register.

Apply fluent validations in ASP.NET Core minimal API to prevent dirty data. Install fluent validation, register validators from assemblies, and validate login detail DTOs before database operations.

Learn to handle file uploads in a minimal api by uploading a battery payload and original file name, storing the image on disk, and saving the url in the database.

Explore adding http request filters in .NET 7 minimal APIs to validate inputs, handle exceptions, and log requests. Learn to build reusable di-friendly endpoint filters and test via swagger.

Master minimal api development with restful principles, leverage Entity Framework for database design and interactions, and secure apis with http filters to write less code while building great apis.
