Container-Neutral Dependency Registry

• ID: runtime.dependency-registry
• Name: Container-neutral dependency registry
• Maturity: GA
• Summary: Tracks DependencyDescriptor entries, blocks conflicting registrations, and supports explicit collection-registration semantics.

What It Does

IDependencyRegistry is the runtime registration abstraction used by modules. DependencyRegistry stores descriptors and enforces rules before container-specific adapters translate registrations.

Public Surface

Packages

• LiteBus.Runtime
• LiteBus.Runtime.Abstractions

Requires

• runtime.module-configuration

Invariants

• Conflicting non-collection bindings for same service type fail.
• Collection registrations require collection-marked descriptors.
• Duplicate equivalent descriptors are ignored.

Non-Goals

• Runtime service resolution.

Observability

No direct telemetry. Registration conflicts throw LiteBusConfigurationException.

Test Coverage

Covered Use Cases

DependencyRegistryTests.Register_WithConflictingBindingForSameServiceType_ShouldThrowLiteBusConfigurationException

• Test kind: Unit
• Expected outcome: conflicting binding is rejected

DependencyRegistryTests.RegisterCollection_ShouldAllowMultipleImplementations

• Test kind: Unit
• Expected outcome: multiple collection items are accepted

DependencyRegistryAdapterTests.MicrosoftAdapter_RegisterCollection_ShouldAllowMultipleImplementations

• Test kind: Unit
• Expected outcome: Microsoft DI adapter preserves collection semantics

Untested Use Cases

Out-of-Scope Use Cases

• Post-build service replacement.
