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.

Our messages

For this microservice, we are choosing to not have reply messages. There's nothing saying any one way is better than the other. If you believe that you need response messages in order to validate the chain of custody or just to log compliance, then feel free to create a message, register it, subscribe, and process it accordingly. For our purposes we will simply send requests and assume they were processed.

The first message is for our Wikipedia search. The second message is for our text to speech translation:

public class WikipediaSearchMessage

public int maxReturns { get; set; }
public string searchTerm { get; set; }
}
[Queue("Speech", ExchangeName = "EvolvedAI")]
[Serializable]
public class SpeechRequestMessage

public int ID { get; set; }
public string text { get; set...
