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.

Modifying the Azure Function code

While this is all quite exciting (it should be, this is really cool tech), we need to make a few changes to the Azure Function to meet our requirements:

  1. Identify the return statement in your Azure Function. It will look as follows:
      return name == null 
        ? req.CreateResponse(HttpStatusCode.BadRequest,
         "Please pass a name on the query string or in the request 
        : req.CreateResponse(HttpStatusCode.OK, "Hello " + name); 

Let's simplify the code a bit and just return true if the email address is not empty. Replace the return statement with the following code:

      if (email == null) 
        return req.CreateResponse(HttpStatusCode.BadRequest,
         "Please pass an email address on the query string or
          in the request body"); 
        bool blnValidEmail = false; 
        if (email.Length > 0) 
            blnValidEmail = true;
