Building a RESTful API with ASP.NET Core 3
Building an API is one thing, but building a truly RESTful API is something different. In this course, you'll learn how to build one using ASP.NET Core 3.
What you'll learn
In this course, you'll learn how to build a RESTful API with ASP.NET Core 3. Creating a truly RESTful API is quite different from creating a regular web API, but in this course, Building a RESTful API with ASP.NET Core 3 , you’ll learn how. You'll start by exploring how to interact with your API using the correct HTTP methods and status codes, and what method safety and idempotency are all about. Next, you'll learn how to validate input that’s sent to the API, and how to implement common features like filtering and searching. By the end this course, you’ll know all about REST constraints, what the advantages are, and how to implement them when building your API with ASP.NET Core 3.
