Master decorator pattern best practices in C# including code organization, maintainability tips, DI integration, and common pitfalls to avoid.

We Are .NET

A practical guide to applying the decorator pattern well in C# production codebases. Covers single-responsibility decorators, abstract base classes, naming conventions ('{Concern}{Component}Decorator'), project folder structure, composition order, thread safety with ConcurrentDictionary, and testing strategies using mocks. Also highlights common pitfalls: breaking interface contracts, swallowing exceptions silently, circular DI chains, deep chain performance overhead, and leaking decorator implementation details. Includes guidance on integrating with IServiceCollection and Scrutor for centralized decorator composition.
