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 going to create custom messages for bonds and for CDSs. The following code shows what they look like when completed. Notice that we use the queue attribute to make sure the end location of the message is correctly known—at least the queue and exchange parts anyways!

CDS-request message

This is how our CreditDefaultSwapRequestMessage looks. You can see that we use the queue and exchange attributes to direct our message to the correct queue and exchange:

[Queue("Financials", ExchangeName = "EvolvedAI")]
[Serializable]
public class CreditDefaultSwapRequestMessage
{
public double fixedRate { get; set; }
public double notional { get; set; }
public double recoveryRate...
