C# Abstractions, the lies they tell us, and the fact your likely still doing it wrong

Abstractions are one of the most powerful concepts in software engineering. They help us manage complexity, improve maintainability, and write cleaner code. But not all abstractions are created equal. In fact, some abstractions can hide important details, introduce unnecessary complexity, and lead developers down architectural paths that create more problems than they solve.

In this session, we'll take a practical and sometimes uncomfortable look at C# abstractions, the assumptions they encourage, and the common mistakes developers continue to make when designing applications. We'll explore how interfaces, dependency injection, repository patterns, service layers, and other popular abstraction techniques are often misunderstood, overused, or applied without fully understanding their trade-offs.

Through real-world examples and lessons learned from production environments, you'll discover when abstractions add value, when they become harmful, and how to make better architectural decisions that improve both code quality and developer productivity.

Whether you are a C# developer, software engineer, architect, technical lead, or aspiring developer, this session will challenge conventional thinking and help you build more maintainable, efficient, and pragmatic .NET applications.
