Description

Is your team suffering the symptoms of the monolithic hell? Has your code base become so complex it’s too hard to understand and modify? Does it take forever to build and deploy your system? Do you just want to know what’s the latest in distributed systems architecture?

Inthiscourseyouwilllearn why everyone is moving to microservices and how to get started with C# and the .NET platform.

Here for some of the things you will learn in this course:

  • What is a monolith and the typical issues it presents over time

  • What are microservices, the problems they solve and when to use them

  • A quick view of the building blocks of a .NET microservices based architecture

  • How to create a microservice from scratch using .NET 5 and Visual Studio Code

  • Use C# 9 record types to define Data Transfer Objects (DTOs)

  • How to implement a microservices REST API with ASP.NET Core and Swagger UI

  • How to use the repository pattern to persist data into a MongoDB NoSQL database

  • What is Docker and how to run a MongoDB container in your box

  • What is dependency injection and how to use it in ASP.NET Core apps

  • How to use the ASP.NET Core configuration system

We will not jump straight to the ideal implementation, we will start with a very simple and “nave” implementation, we will learn about common mistakes when implementing microservices, we will learn about multiple techniques and patterns in the microservices world and finally we will arrive to a nice implementation based on best practices.

This is a beginner level course, so I intentionally take my time to explain every new concept in a very didactic way to ensure you understand the purpose of the code you are about to write. You will find no magic code copied from external or hidden sources. We will start absolutely from scratch and I will explain every line of code as I add them to the projects.

You should have some basic C# knowledge and ideally some web development experience to make the most of this course. However, I make no assumptions on your previous knowledge of ASP.NET Core or of any of the other libraries, tools and techniques used during the course. As long as you are eager to learn by doing, I think you will really enjoy this course since I will explain everything I do as we write the code together.

By the end of this course, you will have a fully working .NET based microservice, but most importantly, you will understand every line of code and why we ended up with the final implementation.
