Fleans.Application.Abstractions

Abstractions package for Fleans worker plugins. Contains the Orleans grain interfaces that span Core ↔ Worker silos (IScriptExecutorGrain, IConditionExpressionEvaluatorGrain, ICustomTaskCatalogGrain, narrow IWorkflowInstanceCallback), the custom-task schema records (CustomTaskParameterSchema, CustomTaskRegistration, CustomTaskCatalogEntry), MappingResolver, WorkflowLoggingContext / WorkflowContextKeys, and the stream-namespace constants (WorkflowEventStreams).

Depends only on Fleans.Domain.Abstractions (the true leaf) + Microsoft.Orleans.Sdk + Microsoft.Extensions.Logging.Abstractions. No reference to Fleans.Application, Fleans.Domain, or any persistence project.

Dependency closure

Fleans.Application.Abstractions  →  Fleans.Domain.Abstractions

Used by:

  • Fleans.Worker — depends on this package, which transitively pulls Domain.Abstractions.
  • Fleans.Application — internal engine implementation, depends on this package for the shared grain interfaces it implements.

Minimum consumer usage

using Fleans.Application.Abstractions.Events;

[ImplicitStreamSubscription(WorkflowEventStreams.ExecuteCustomTaskStreamNamespace)]
public sealed class MyHandler : Grain, IGrainWithStringKey, IAsyncObserver<ExecuteCustomTaskEvent>
{
    // ...
}

Plugin packages share the engine's <VersionPrefix> track — every Fleans release bumps every plugin's NuGet version even when the plugin source is bit-identical (same precedent as Aspire.Hosting.* / Microsoft.Orleans.*).

See Fleans documentation for the full plugin guide.
