By: Dirk Strauss, Jas Rademeyer

Overview of this book

.NET Core is a general purpose, modular, cross-platform, and open source implementation of .NET. With the latest release of .NET Core, many more APIs are expected to show up, which will make APIs consistent across .Net Framework, .NET Core, and Xamarin. This step-by-step guide will teach you the essential .NET Core and C# concepts with the help of real-world projects. The book starts with a brief introduction to the latest features of C# 7 and .NET Core 2.0 before moving on to explain how C# 7 can be implemented using the object-oriented paradigm. You'll learn to work with relational data using Entity Framework and see how to use ASP.NET Core practically. This book will show you how .NET Core allows the creations of cross-platform applications. You'll also learn about SignalR to add real-time functionality to your application. Then you will see how to use MongoDB and how to implement MongoDB into your applications. You'll learn about serverless computing and OAuth concepts, along with running ASP.NET Core applications with Docker Compose. This project-based guide uses practical applications to demonstrate these concepts. By the end of the book, you'll be proficient in developing applications using .NET Core 2.0.

Chapter 7. A Serverless Email Validation Azure Function

This chapter will take us into the realm of serverless computing. Just what is serverless computing, I hear you ask? Well, the answer is really simple once you grasp the idea that the term serverless computing has nothing to do with the lack of a server. It is quite the opposite, in fact.

In this chapter, we will have a look at:

  • Creating an Azure Function
  • Testing your Azure Function in the browser
  • Calling an Azure Function from an ASP.NET Core MVC application

We will be creating a simple Azure Function that uses regular expressions to validate an email address. You need to keep in mind that Azure Functions are small pieces of code in the cloud. Do not think of them as large sections of complicated code. The smaller the better.
