CasCap.Common.Abstractions

Core interface definitions shared across the CasCap ecosystem. This project provides the foundational contracts that other CasCap libraries and applications may depend upon.

Installation

dotnet add package CasCap.Common.Abstractions

Purpose

This library contains no concrete implementations — only interfaces and abstractions that define the contracts between components.

Target frameworks: netstandard2.0, net8.0, net9.0, net10.0

Interfaces

Interface Description
Marker interface implemented by all application configuration records to allow easy identification and generic constraint usage
Identifies a feature-gated background service — exposes a string FeatureName and ExecuteAsync entry point. Matched case-insensitively against the enabled features set at startup
[Obsolete] Generic predecessor of IBgFeature that used a bitwise feature-flag enum via FeatureType. Retained for backward compatibility
Generic write-path event sink contract (unconstrained — accepts both reference and value types). Exposes a SinkType property for targeted dispatch filtering. Domain events are fanned out to every registered IEventSink<T> implementation in parallel. Read-path queries are defined by domain-specific interfaces (e.g. IFroniusQuery, IKnxQuery) in the consuming projects
Abstraction for an in-process cache provider supporting Get, Set, Delete, and DeleteAll
Represents a blob with associated metadata (bytes, DateCreatedUtc, BlobName, SizeInBytes, HasImage)
Abstracts a notification service capable of sending and receiving messages with optional attachment support
Represents an outgoing notification message (text, sender, recipients, attachments)
Metadata for an attachment received as part of a notification (Id, ContentType)
Represents a named group in a notification service (Id, Name, members)
Response returned after sending a notification (Timestamp)
Represents a notification received from an external messaging service (Sender, GroupId, Message, attachments)
Abstraction for persisting HTTP audit entries (net8.0+ only)
Exposes Azure Blob Storage connection properties (endpoint/connection string, container name, health check probe type) for feature-specific configuration records
Exposes Azure Table Storage connection properties (endpoint/connection string, health check probe type) for feature-specific configuration records
[Obsolete] Pairs with IFeature<T> to carry the enabled EnabledFeatures flags into the BackgroundService launcher
Exposes Kubernetes-specific runtime properties (node name, pod name, namespace, pod IP, service account name)
Exposes OpenTelemetry metric configuration (metric name prefix, OTel service name)

Enums

Type Description
[Flags] enum for Kubernetes container health probe types: None, Readiness, Liveness, Startup

Configuration Types

Type Description
Basic authentication settings for a REST API (Username, Password, AnonymousPathPrefixes)
Dictionary of name →
Per-sink settings: Enabled, and a Settings dictionary for sink-specific key/value settings
Compile-time constants for common sink setting keys

Models

Type Description
Represents a single HTTP request/response audit record — Source, HttpMethod, RequestUri, StatusCode, ElapsedMs, RequestBody, ResponseBody (net8.0+ only)

Event Models

Type Description
A comms stream entry with Source, Message, TimestampUtc, and optional JsonPayload for AI agent context

Attributes

Attribute Description
Decorates implementations with a string type name (e.g. "Redis", "AzureTables", "Console") used by for discovery

Extension Methods

Method Description
Discovers and registers all implementations in the supplied assembly whose name is enabled in
KubernetesProbeTypes.GetTags() Returns the string health-check tag array for a probe type ("ready", "live", "startup")

Contract

string SinkType { get; }
Task InitializeAsync(CancellationToken cancellationToken);
Task WriteEvent(T @event, CancellationToken cancellationToken = default);
Task HousekeepingAsync(IReadOnlyCollection<string> validIds, CancellationToken cancellationToken = default);

SinkType is a self-describing property that each implementation sets to its own sink identifier (e.g. "Redis", "AzureTables", "Console"). This enables targeted dispatch filtering at runtime without reflection. The value should match the string passed to on the same class.

InitializeAsync and HousekeepingAsync have default no-op implementations so that sink authors only need to implement SinkType and WriteEvent.

Read-path queries (retrieving stored events, snapshots) are intentionally not part of this interface. Each domain defines its own query interface (e.g. IFroniusQuery, IKnxQuery) with methods tailored to the domain's access patterns. This follows the Interface Segregation Principle — write-only sinks (e.g. Console, SignalR) are not forced to implement read methods they cannot support.

Dependencies

The only valid dependencies for this library are other Abstractions-style libraries.
