ASP.NET Web API Tutorials

In this ASP.NET Web API Tutorials For Beginners and Professionals series, I will cover all the features of ASP.NET Web API. You will learn from basic to advanced level features of ASP.NET Web API. The term API stands for Application Programming Interface, and ASP.NET Web API is a framework provided by Microsoft that makes it easy to build Web APIs, i.e., it is used to develop HTTP-Based Web Services on top of .NET Framework.

Today, a web-based application cannot reach all its customers or users. People have become very smart, which means they use iPhones, mobile devices, tablets, etc., daily. These devices have many useful apps that make their lives easy. In simple words, we can say that we are moving from the web toward the app world.

So, if we like to expose our service data to the browsers and to all these modern device apps in a fast, secure, and simple way, we should have an API compatible with all browsers and all these modern devices.

Prerequisites to Learn ASP.NET Web API

Learning ASP.NET Web API effectively requires understanding several underlying concepts and technologies. Below are the prerequisites that should ideally be covered before diving into ASP.NET Web API. If you don’t know the following concepts, then don’t worry. We will explain each concept in detail.

  • C# Programming: Since ASP.NET Web API is a framework where we need to write the code using C#, you should have a good understanding of C#, including control flow, classes, objects, generics, collections, exception handling, and asynchronous programming.
  • Entity Framework and LINQ: For Data-Driven APIs, knowledge of Entity Framework, an ORM (Object-Relational Mapper) for .NET, is beneficial. LINQ is also important for querying databases within the .NET environment.
  • RESTful Services: It is essential to understand the principles of RESTful services, including resource-based architecture, statelessness, HTTP methods (GET, POST, PUT, DELETE), and status codes.
  • JSON/XML: Familiarity with JSON and XML, the two most common formats for sending and receiving data in web APIs.

Note: If we missed any concept of ASP.NET Web API, please let us know by commenting in the comment box. We promise to write an article and publish it as soon as possible in this course.
