Stratara.Abstractions
License: FSL-1.1-MIT (Functional Source License — source-available; converts to MIT after 2 years). Not OSI-approved OSS.
Contract interfaces and wire-level POCO records for the Stratara framework. Library-safe — depends only on Microsoft.Extensions.DependencyInjection.Abstractions, Microsoft.Extensions.Logging.Abstractions, and Stratara.Contracts. No EF Core or message-bus runtime.
Use this when you need to reference Stratara types without pulling in any concrete implementation (Mediator runtime, EF Core, RabbitMQ, etc.). Typical consumers: handler/projection libraries that ship without a host.

Why split
NuGet consumers without an event-sourcing host can adopt Stratara's CQRS contracts and authorization model without dragging in EF Core, RabbitMQ, or the WriteStore.

NuGet packages (13)
Showing the top 5 NuGet packages that depend on Stratara.Abstractions:
| Package | Downloads |
|---|---|
|
Stratara.Sessions
ASP.NET Core middleware and provider for Stratara's Actor/Subject session model. Reads tenant and user from JWT claims (or X-Tenant-Id / X-Client-Id headers) and populates the ambient ISessionContextProvider for every request. |
|
|
Stratara.Mediator
In-process mediator with DI-resolved handlers and pipeline behaviors for the Stratara framework. MediatR-style routing via typed wrapper cache, plus an authorizing decorator and a bucket-lock concurrency primitive. |
|
|
Stratara.Security
Dependency-light key-store and envelope encryption for the Stratara framework. Production IKeyStore implementation (EnvelopeFileKeyStore) with KEK-wrapped, versioned per-scope DEKs (rotation + revoke + crypto-shred), a file-backed master-key provider, and an AES-GCM blob encryptor with purpose-bound associated data. References only Stratara.Abstractions + BCL crypto — no EF Core, RabbitMQ, Redis, or cloud SDKs. |
|
|
Stratara.Validation
Vendor-neutral request validation for the Stratara framework — a mediator pipeline behavior that runs IValidator<T> implementations before the handler and throws an aggregated StrataraValidationException on failure. No FluentValidation dependency; an optional adapter is shipped separately. |
|
|
Stratara.Resilience
Polly-based named resilience pipelines pre-wired for the Stratara framework's messaging and command/event dispatch paths. Four named pipelines registered via AddResiliencePipelines(). |

### Added
- **Configurable snapshot strategy** (`Stratara.Abstractions`, `Stratara.Infrastructure`) — the
snapshot cadence is no longer hard-coded. A new `Stratara.Abstractions.EventSourcing.ISnapshotStrategy`
decides, per stream, whether the event-sourcing runtime should write a snapshot:
`bool ShouldSnapshot(Type aggregateType, long currentVersion, long lastSnapshotVersion)`.
`AddEventSourcing()` registers the default `VersionThresholdSnapshotStrategy` (snapshot every 50
versions — identical to the previous behaviour) via `TryAddSingleton`, so existing consumers see no
change. To take over the policy, register your own singleton `ISnapshotStrategy` (it overrides the
default whether registered before or after `AddEventSourcing()`): vary the threshold per aggregate
type, construct `new VersionThresholdSnapshotStrategy(threshold)` for a different uniform cadence, or
register `NoSnapshotStrategy` to disable snapshotting entirely. This replaces the previously
hard-coded `UseSnapshots`/`SnapshotRange` constants in the default snapshot service, which were not
actually configurable despite the documentation implying they were.
- **`AddDomainEventTypesFromAssemblyContaining<T>()`** (`Stratara.Abstractions`) — registers *only* the
domain event types consumed by an assembly's aggregate `Apply(TEvent)` methods in the trusted-type
resolver, without registering the aggregate types themselves and without pulling any projection / saga
/ command-handler classes into DI. Use it in a host that only needs to deserialize event payloads off
the message bus or event stream — typically a dedicated projection or saga worker — but must not wire
the handler classes (and their runtime dependencies) that `AddProjectionsFromAssemblyContaining<T>`
would register. Complements the existing `AddAggregatesFromAssemblyContaining<T>` (which additionally
registers the aggregate types) and `AddTrustedType<T>` (single type).
