Mastering ASP.NET Web API

By: Mithun Pattankar

Overview of this book

Microsoft has unified their main web development platforms. This unification will help develop web applications using various pieces of the ASP.NET platform that can be deployed on both Windows and LINUX. With ASP.NET Core (Web API), it will become easier than ever to build secure HTTP services that can be used from any client. Mastering ASP.NET Web API starts with the building blocks of the ASP.NET Core, then gradually moves on to implementing various HTTP routing strategies in the Web API. We then focus on the key components of building applications that employ the Web API, such as Kestrel, Middleware, Filters, Logging, Security, and Entity Framework.Readers will be introduced to take the TDD approach to write test cases along with the new Visual Studio 2017 live unit testing feature. They will also be introduced to integrate with the database using ORMs. Finally, we explore how the Web API can be consumed in a browser as well as by mobile applications by utilizing Angular 4, Ionic and ReactJS. By the end of this book, you will be able to apply best practices to develop complex Web API, consume them in frontend applications and deploy these applications to a modern hosting infrastructure.

Creating ASP.NET Core Project using Visual Studio IDE

We will now create an ASP.NET Core Web API application using Visual Studio 2017 IDE. Ensure this prerequisite before starting:

Install Visual Studio 2017 (do select the .NET Core SDK options while installation). We will be using the community edition all the way. ASP.NET Core 2.0 Preview 2 is used throughout this book

Let's get started with building the ASP.NET Core Web API step by step:

Open Visual Studio 2017 IDE, click on New Project to open the project templates dialog.
Under Visual C# Templates, click on .NET Core, and select ASP.NET Core Web Application as shown in the following screenshot:

We can also create an ASP.NET Core web application targeting the full .NET framework by web template under the Visual C# section

Provide an appropriate project name like...
