This article in the C# garbage collector series outlines the history and types of GC in .NET. It covers three GC modes:
LIFO method, stores value types like structs and enums, while the heap handles reference types like strings. Key concepts like boxing and unboxing are covered, showing how value types can be converted to reference types and vice versa. The article emphasizes the importance of efficient memory management and the role of the garbage collector in .NET, particularly in managing heap memory and optimizing overall application performance.Single and SingleOrDefault in C#, addressing the misconception that they always traverse an entire Enumerable. It explains the actual behavior of these methods, both with and without a predicate, contrasting them with First and FirstOrDefault. The article clarifies that SingleOrDefault efficiently handles different scenarios, such as returning a default value, the only item, or throwing an error when multiple items exist. It emphasizes the operational differences and efficiency O(1) without predicate and O(N) with predicate of these methods, offering valuable insights for C# developers seeking to optimize their code.EventStoreDbContext class. The tutorial showcases the EventLoggerBehavior in MediatR for logging Command actions and responses, utilizing a Convention over Configuration approach. This part provides a practical guide for effectively tracking and understanding system state changes in a CQRS application through event history.IPipelineBehavior interface, demonstrating how to write reusable, efficient code that adheres to the DRY principle. The article provides practical examples and code snippets, showing how these behaviors enhance functionality and error handling in an ASP.NET Core application.INotification and INotificationHandler for event handling, illustrated with a CustomerCreatedEvent. This setup allows for separate event handlers for different actions like email notifications and logging, adhering to the Single Responsibility Principle. The tutorial provides code examples for integrating these features into an ASP.NET Core application, setting the stage for the next part on MediatR behaviors and aspect-oriented programming.IRequest interface, and handling them with IRequestHandler. It features a real-world example of adding a customer to a database, showcasing command creation, immutability, and the use of Entity Framework and AutoMapper. The article emphasizes decoupling in request handling, aligning with the Hollywood Principle, and provides a glimpse into future topics like Fluent Validation. A must-read for developers looking to enhance their CQRS skills.Command and Query functions, highlighting the benefits of this separation for technology choice and scalability. The piece also touches on the concept of events and Event Sourcing, showcasing their roles in maintaining system states and facilitating troubleshooting. The use of the Event Store database for implementing Event Sourcing is briefly introduced, offering a comprehensive view of the CQRS pattern and its practical application.IAirTrafficControl interface to the implementation of AirbusAirplane and BoeingAirplane classes. The article concludes with the JFKAirTrafficControl class, demonstrating the pattern’s role in facilitating effective object interaction. Ideal for those interested in applying design patterns in software engineering.
