Remarks¶

This resolver favors the generic API surface (GetService, GetServices) for performance, while still supporting non-generic APIs (GetService, GetServices) through an internal type registry.

Registration semantics:

• GetService returns the most recently registered service for the type (last registration wins).
• GetServices returns all registrations (order is implementation-defined by the underlying containers/registry).
• Contracts provide named variants of the same service type.

Disposal semantics:

• Constants and lazy singletons that implement IDisposable are disposed when the resolver is disposed.
• Exceptions thrown from callbacks or disposal actions are suppressed during Dispose.

Thread-safety:

• Registration-change callbacks and disposal action bookkeeping are thread-safe.
• Resolve operations avoid additional locking within this type; underlying containers/registry are expected to be concurrency-safe for their usage patterns.
