Reflection Use Cases
Question
Where can reflection be useful?
Short interview answer
Reflection is useful for frameworks and tools that inspect metadata at runtime, such as serializers, dependency-injection containers, test runners, plugin loaders, and type browsers.
Detailed answer
The common pattern is to discover types or attributes and then apply a convention. For example, a plugin host can find implementations of an interface in an assembly; a serializer can inspect public properties or annotations. Keep reflection at the boundary of such infrastructure instead of spreading string-based member access through application code.
