Packages

Runtime packages target net8.0 and net10.0, carry XML documentation, and are Native AOT compatible. The analyzer package is a compiler extension and targets netstandard2.0. MIT licensed. For package-specific setup, see Package docs. For a task-oriented install map, see Package add-ons.

Package	What it is	Depends on
Pulse.Mqtt.Core	Wire codec (all 15 control packets, MQTT 5.0 + 3.1.1), transports (TCP/TLS, in-memory loopback), MqttConnection, RawMqttClient, every swap-point contract	BCL + System.IO.Pipelines only
Pulse.Mqtt.Client	ResilientMqttClient: supervision, topic routing, typed messaging, request/response, diagnostics	Core, Microsoft.Extensions.Logging.Abstractions
Pulse.Mqtt.Dataflow	ISourceBlock<T> adapters for messages, routes, acknowledged routes, and state transitions	Client
Pulse.Mqtt.DependencyInjection	AddPulseMqttClient, named clients, options binding, hosted lifecycle, health checks	Client + Microsoft.Extensions.* abstractions
Pulse.Mqtt.Endpoints	Minimal-API-style MapMqtt endpoints with route constraints and per-message scopes	Client, DependencyInjection
Pulse.Mqtt.Serialization.Json	Source-generated System.Text.Json serializer	Client
Pulse.Mqtt.Serialization.MessagePack	MessagePack serializer (compact binary, source-generated resolvers)	Core, MessagePack
Pulse.Mqtt.Serialization.Protobuf	Protocol Buffers serializer (compact binary, explicit parser registry)	Core, Protobuf runtime
Pulse.Mqtt.Resilience.Polly	PollyReconnectStrategy over a Polly v8 ResiliencePipeline	Core, Polly.Core
Pulse.Mqtt.Storage.LiteDB	LiteDbSessionStore + LiteDbMessageStore: subscriptions, the offline queue, and in-flight QoS state survive restarts	Core, LiteDB
Pulse.Mqtt.Storage.SqlServer	SqlServerSessionStore + SqlServerMessageStore: subscriptions, the offline queue, and in-flight QoS state survive restarts in SQL Server	Core, Microsoft.Data.SqlClient
Pulse.Mqtt.Storage.Sqlite	SqliteSessionStore + SqliteMessageStore: subscriptions, the offline queue, and in-flight QoS state survive restarts	Core, Microsoft.Data.Sqlite
Pulse.Mqtt.Transport.WebSocket	MQTT over ws/wss	Core
Pulse.Mqtt.Transport.Quic	MQTT over QUIC, one bidirectional stream (.NET 10 only)	Core
Pulse.Mqtt.Testing	PulseMqttTestBroker, the in-process broker with opt-in retained messages, persistent sessions, and scripted responses	Core
Pulse.Mqtt.Analyzers	Optional C# diagnostics for common Pulse MQTT usage mistakes	none

Which do I need?

• A typical service: Client + DependencyInjection + Serialization.Json.
• Minimal footprint / your own composition: Client alone (or Core alone for the raw layers).
• Tests: add Testing.
• Pipeline-style consumers: add Dataflow.
• Compact binary payloads: add Serialization.MessagePack or Serialization.Protobuf.
• Polly policies or WebSocket brokers: add the matching add-on.
• Compile-time guidance: add Analyzers with PrivateAssets="all".
