Asp.Net Core Minimal Apis For Complete Beginners (.Net 10)

What you'll learn
Build a Minimal API from scratch using .NET 10 and Visual Studio 2026
Implement full CRUD functionality using GET, POST, PUT, and DELETE endpoints in Minimal APIs
Design and apply clean architecture principles to create a maintainable and scalable API
Integrate SQL Server using Entity Framework Core
Secure your API by adding authentication and authorization with an API key
Add structured and configurable logging to your Minimal APIs using Serilog
Test and explore your API endpoints effectively using Swagger
Write and run unit tests for your endpoints using xUnit v3 to ensure quality and reliability
Requirements
A solid understanding of C# fundamentals, including variables, fields, properties, and access modifiers
General knowledge of RESTful APIs and the differences between GET, POST, PUT, and DELETE methods
Basic familiarity with ASP.NET Core is helpful, but not required, as the course walks through building an application from scratch
Prior experience with ASP.NET or ASP.NET Core controllers is beneficial but not mandatory
Some exposure to concepts such as dependency injection, Entity Framework Core, logging, authentication, authorization, or unit testing is helpful but not required
Familiarity with Visual Studio and having it installed on your machine to follow along with the examples
Description
This course teaches how to build modern, production ready Minimal APIs using .NET 10 and C# with Visual Studio 2026. It uses the GET, POST, PUT, and DELETE methods in Minimal APIs to demonstrate how to design clear and expressive HTTP endpoints from the very beginning. You will start by understanding the fundamentals of Minimal APIs and how they differ from traditional controller based APIs, then gradually move toward designing a well structured solution that follows clean architecture principles. The course emphasizes clear separation of concerns so your application remains easy to maintain, test, and extend as requirements grow.As you progress, you will integrate SQL Server using Entity Framework Core and DbContext, learning how to model data, manage migrations, and perform efficient data access. You will also implement structured logging with Serilog to capture meaningful diagnostics and configure a global exception handler to ensure consistent and reliable error handling across the entire API.Security is a core theme throughout the course. You will add API key based authentication to protect endpoints, apply an EndpointFilter that uses feature flags, and write comprehensive unit tests using xUnit v3 to validate business logic and ensure long term stability. Swagger is used extensively for testing, documentation, and exploration of the API, giving you confidence in every endpoint you build and helping you follow modern .NET best practices from start to finish.
