Hands-On Microservices with C#

By: Matt Cole

Overview of this book

C# is a powerful language when it comes to building applications and software architecture using rich libraries and tools such as .NET. This book will harness the strength of C# in developing microservices architectures and applications. This book shows developers how to develop an enterprise-grade, event-driven, asynchronous, message-based microservice framework using C#, .NET, and various open source tools. We will discuss how to send and receive messages, how to design many types of microservice that are truly usable in a corporate environment. We will also dissect each case and explain the code, best practices, pros and cons, and more. Through our journey, we will use many open source tools, and create file monitors, a machine learning microservice, a quantitative financial microservice that can handle bonds and credit default swaps, a deployment microservice to show you how to better manage your deployments, and memory, health status, and other microservices. By the end of this book, you will have a complete microservice ecosystem you can place into production or customize in no time.

Adding Speech and Search to Your Microservice

In this chapter we are going to build an exciting, dual purpose microservice.

We will learn:

How to use the Microsoft Text-to-Speech (TTS) engine
How to build a microservice that can respond to speech requests
How to use Text to Speech for search results

The internals are built around TTS specifically, the Microsoft Speech API. More concretely, we will use the TTS engine. Our microservice will be responsible for talking back to us, something I've always discouraged my children from ever doing to me, yet here I am programming a computer to do the same. But that's an entirely different book..

Our microservice will provide two unique pieces of functionality. First, you will be able to send a message and have the microservice repeat what you typed. You will have your choice of a male or female voice, the ability to set the...
