Building a REST API with ASP.NET Core

Building a REST API with ASP.NET Core and SQL Server is a practical way to create fast, secure, and scalable backend applications. ASP.NET Core provides a modern development framework for handling requests, processing business logic, and returning structured data, while SQL Server is used to store and manage application data efficiently.

In this blog, readers will learn how to create a REST API project from scratch and connect it with a SQL Server database. The process includes setting up the project, configuring the database connection, creating models, adding Entity Framework Core, and generating database tables through migrations.

The blog will also explain how controllers and API endpoints are created for common CRUD operations. These operations include creating new records, retrieving data, updating existing information, and deleting records from the database. Readers will also learn how to test API endpoints using tools such as Swagger or Postman.

Additional topics will include request validation, error handling, dependency injection, and organizing the project into a clean and maintainable structure. By the end of the blog, readers will understand how ASP.NET Core and SQL Server work together to build a complete REST API that can be connected to web, mobile, or desktop applications.
