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.

Implementing our interface

If you remember what we talked about earlier with inheritance, we now need to implement the interface methods we are getting from IBaseMicroService. Let's begin with our Start method. This method basically configures and starts our timer for us:

public virtual bool Start(HostControl hc)
{_host = hc;
Console.WriteLine(_name + string.Intern("Service Started."));
Assumes.True(_timer!= null, string.Intern("_timer is null"));
_timer.AutoReset = true;
_timer.Enabled = true;
_timer.Start();
return true;
}

Next comes our Stop method. This method will log that our service has stopped, stop our timer, and close our RabbitMQ connections and channels for proper cleanup:

public virtual bool Stop()
{
Assumes.True(_log != null, string.Intern("_log is null"));
_log?.Info(_name + string.Intern(" Service is Stopped"));
Assumes.True(_timer...
