Ever felt the tedium of writing the same code over and over in C#? This often stems from the absence of a 'pattern' keyword in C#, compelling developers to code at a lower level of abstraction than ideal, leading to unnecessary repetition and boredom. However, there's a solution to bridge this abstraction gap: the use of aspects. Aspects have been invented to encapsulate concerns that traditional object-oriented programming doesn't efficiently address, thus significantly reducing boilerplate code. In this session, we will delve into five aspect-oriented techniques, complete with practical examples: ASP.NET middleware, DI-based and IL-based AOP frameworks, source generators, and Roslyn-based AOP frameworks. Attendees will not only gain practical insights into crafting cleaner, more efficient code but also learn strategies that enhance long-term project sustainability and boost developer productivity. Join us to add a new dimension to your conceptual toolkit.
