This Specialization provides a structured path to building modern Web APIs with ASP.NET Core 8, covering design, development, security, testing, deployment, and scalability. It begins with Web API design principles and ASP.NET Core fundamentals, helping learners understand application architecture, API workflows, and the framework features needed to create maintainable services. Learners then explore data access and persistence with Entity Framework Core, including data modeling, entity relationships, and practical techniques for working with application data. The program also introduces identity, authentication, and authorization concepts, along with testing practices that improve software quality and reliability. Through unit and integration testing, learners gain confidence in API behavior and correctness. The final course focuses on extending, operating, and scaling production-ready services. Topics include gRPC, GraphQL, SignalR, error handling, monitoring, observability, cloud-native development, and automated deployments using Azure Pipelines and GitHub Actions. By completing all three courses, participants gain a comprehensive understanding of the ASP.NET Core Web API lifecycle, from design and implementation to testing, deployment, optimization, and operational readiness. This Specialization is based on the book Web API Development with ASP.NET Core 8, by Xiaodi Yan

Modern applications rely on well-designed web APIs to enable communication between systems, services, and clients. This course teaches the core principles of API design and development using ASP.NET Core, helping learners build scalable, maintainable, and industry-standard web services. Throughout the course, learners will develop practical skills in designing RESTful APIs, understanding alternative API architectures such as gRPC and GraphQL, and implementing API functionality using ASP.NET Core. By exploring routing, configuration, dependency injection, middleware, logging, and data access, learners will gain the knowledge needed to create robust APIs for real-world applications. What sets this course apart is its balanced approach to both conceptual understanding and hands-on implementation. Learners not only study API design principles but also apply them through practical examples and Entity Framework Core-based data access scenarios. This course is ideal for aspiring and practicing .NET developers, software engineers, and IT professionals who want to build modern web APIs. A basic understanding of C# programming and object-oriented development concepts is recommended. This course is part one of a three-course Specialization designed to provide a comprehensive learning pathway in this subject area. While it delivers standalone value and practical skills, learners seeking a more integrated and in-depth progression may benefit from completing the full Specialization.
