- 1500+ of acceptance tests.
- Thread-safe and lock-free registrations and resolutions.
- Detects recursive dependencies (cycles) in object graph.
- Throws exceptions as early as possible with a lot of details.
- Provides diagnostics for potential resolution problems via
container.Validate()
.
- Registration of service to implementation type mapping (additionally supported: registering once, registration replace, registration removal).
- Registration of delegate factory and already created service instance.
- Batch registration of types from the provided assemblies.
- Registation identified with a service key of arbitrary type and registration of multiple non-keyed implementations for a single service.
- Registration with the condition depending on context.
- Registration with the associated metadata object of arbitrary type.
- Resolve and ResolveMany.
- Service lifetime control via Reuse and lifetime scoping:
- Nested disposable scopes with optional names
- Optional ambient scope context
- Reuse types:
Transient
,Singleton
,Scoped
in multiple flavors (including scoping to the specific service ancestor in the object graph) - Option to
useParentReuse
and touseDecorateeReuse
for decorators - Option to
preventDisposal
andweaklyReferenced
- Open-generics support including type constraints, variance, complex nesting and recurring definitions.
- Constructor parameters injection and optional property and field injection.
- Static and instance factory methods with the parameter injection similar to the constructor parameter injection.
- Injection of properties and fields into the existing object.
- Decorators:
- Nested with the relative order control
- Generic and non-generic
- With the Reuse possibly different from the decorated service
- Decorators of wrapped service
- Wrappers:
- Service collections:
T[]
,IEnumerable<T>
,LazyEnumerable<T>
, andI(ReadOnly)Collection|List<T>
- Single service wrappers:
Lazy<T>
,Func<T>
,Meta<TMetadata, T>
orTuple<TMetadata, T>
,KeyValuePair<TKey, T>
- Currying of constructor or factory method parameters with
Func<TArg, T>
,Func<TArg1, TArg2, T>
, etc - Nested wrappers: e.g.
Tuple<SomeMetadata, Func<ISomeService>>[]
- User-defined wrappers
- Composite
- Service collections:
- User-provided strategies for resolution of unknown service.
- Dynamic registration providers
- Optional automatic concrete types resolution
