Not all abstractions are created equal. Some isolate real volatility and protect your system from change. Others quietly pile up complexity and hide performance problems. Learn when to embrace abstractions versus when they become technical debt that slows down your team.

Abstractions in .NET development come with hidden costs that accumulate over time. While good abstractions isolate genuine volatility like payment processors or external APIs, many common patterns like repository wrappers and pass-through services add unnecessary complexity without real benefits. The key is to abstract policies that might change rather than stable mechanics, wait for actual need before creating interfaces, and regularly evaluate whether abstractions simplify or complicate the codebase. Direct use of mature tools like Entity Framework often provides better performance and clarity than additional abstraction layers.
