Master the Art of Event-Driven Microservices with C# .NET

Course Description:

Welcome to the comprehensive Master course on mastering the development and testing of Event-Driven Microservices using the powerful C# .NET framework. In this course, we will delve into both the theoretical and practical aspects of creating robust microservices, focusing on their event-driven nature.

Development:

• Building Event-Driven API Service: Leverage ASP Net Web API for creating responsive services, coupled with Entity Framework for seamless database operations, and master the art of crafting controllers.
  • ASP Net Web API integration
  • Database access via Entity Framework
  • Developing Controllers
• Building Event-Driven Service Broker: Understand message brokering through RabbitMq, learn how to implement message publishers and subscribers, and design a robust service broker.
  • Configuring RabbitMq as a message broker
  • Implementing Publisher and Subscriber functionalities
• Building Event-Driven UI Portal: Create an engaging user interface with ASP Net Web App, focusing on interacting with the Web API you've built.
  • ASP Net Web App development
  • Consuming Web APIs in the UI
• Containerizing Application: Utilize Docker to containerize your application, and streamline deployment with Docker Compose and advanced networking configurations.
  • Creating Dockerfiles
  • Using Docker Compose for orchestration
  • Running applications with Docker Compose in a fully connected network environment

Testing:

• Testing Application User Interface: Employ Playwright C# .NET for thorough UI testing, ensuring your application's front end performs as expected.
• Testing Application Services: Use Playwright C# .NET to conduct API testing, validating the backend services of your microservice architecture.
• Integration Testing: Dive into testing every component and interaction within your system, including:
  • Testing InMemory API endpoints
  • Validating Publisher functionalities
  • Assessing Subscriber responsiveness
• Containerizing Tests: Streamline your testing process by containerizing your tests for consistent and reproducible outcomes.
• Contract Testing with Pact: Ensure accurate and reliable communication between microservices, both as a Consumer and a Provider, using Pact for testing events and agreements.
  • Testing the Consumer side of the application
  • Testing the Provider side of the application
  • Validating Events through Pact contracts

Technologies Used:

• .NET 7: Stay up-to-date with the latest .NET framework for cutting-edge development practices.
• C# 11: Master the advanced features of C# 11 to write concise, maintainable code.
• ASP.NET Web API: Build scalable and flexible RESTful services.
• ASP.NET MVC Web App: Create dynamic and responsive user interfaces.
• RabbitMq Message Broker: Implement a robust message brokering system for real-time event processing.
• Playwright .NET: Perform end-to-end testing on your applications with ease.
• Integration Testing Libraries: Validate every part of your application's interaction and data flow.
• Docker: Containerize your applications for consistent environments across all stages of development, staging, and production.

By the end of this course, you will have a solid understanding of Event-Driven Architecture and how to develop, containerize, and test event-driven microservices efficiently and robustly with modern approaches. This knowledge will not only enhance your coding skills but also help optimize costs during testing phases, especially when it comes to UI and API testing.

Course Review Synthesis

Pros:

• Comprehensive Content for Advanced Users: The course provides detailed information and advanced insights, with a focus on testing applications in depth. It's praised for its thorough coverage of Event-Driven Systems, making it a valuable resource for those who are already familiar with the basics and looking to delve deeper into the subject.

• Real-World Application: The course applies concepts to real scenarios, which is a plus for learners aiming to understand how to implement these systems in practical environments.

• Expertise Showcased: The course demonstrates an expert's knowledge, as reflected in the content and the depth of explanation provided on complex topics like event-driven microservices and testing of applications.

• Resource Availability: Many resources and materials are available, allowing learners to follow along and implement what they learn without having to seek additional information elsewhere.

🌟 Highlight: The course is particularly recommended for individuals looking to test advanced application setups in an event-driven framework.

Cons:

• Basic Overview Only: The course does not offer a thorough beginner's tutorial; it only provides a basic overview of event-driven concepts. This could be problematic for absolute beginners who would benefit from a more comprehensive introduction to the subject matter.

• Code Quality Concerns: Some reviews criticize the code examples provided, noting issues with SOLID principles and suggesting that direct access to the database context within API layers is not best practice due to lack of separation between data access layer and API layers.

• Configurations and Best Practices Omissions: The course falls short in areas such as detailed RabbitMQ configuration instructions and best practices, which are critical for a comprehensive understanding of event-driven systems.

• Potential for Redundancy: Some of the content may be redundant for those who have already covered basic concepts elsewhere or who can easily access similar information on platforms like YouTube.

⚠️ Caution: The course may not be the best fit for complete beginners or individuals looking to understand the basic foundations of event-driven systems and best practices.

Mixed Feedback:

• Instructional Style: The instructional style is noted to be effective, with the author being able to explain complex concepts such as event-driven microservices well. However, there are comments that the course jumps straight into advanced concepts, which might make it challenging for beginners.

• Value for Money and Time: The course's value is contested; some learners feel it is a waste of money and time due to the lack of learning by doing and because they believe similar content can be found for free online. Others, however, consider it a good investment, especially for its depth on testing applications.

In conclusion, while this course excels in providing detailed and advanced information on Event-Driven Systems, particularly for those looking to test such systems, it may not cater well to complete beginners or individuals seeking a straightforward entry into the topic without prior knowledge. It's advised that potential learners assess their current level of understanding and what they aim to achieve before enrolling in this course.
