# Full OPC UA Part 14 (PubSub) — v1.05.06 This PR replaces the legacy PubSub stack with a modern, **OPC UA Part 14 v1.05.06**-compliant reimplementation built on current .NET: fully `async`, dependency-injection-first with a fluent builder (`services.AddOpcUa().AddPubSub(...)`), NativeAOT/trim-safe, and designed for high-throughput, highly-available, distributed deployments. The libraries — `Opc.Ua.PubSub`, `Opc.Ua.PubSub.Udp`, `Opc.Ua.PubSub.Mqtt`, `Opc.Ua.PubSub.Server`, and `Opc.Ua.PubSub.Adapter` — keep source compatibility with 1.5.378 where practical (obsolete shims) and ship a complete migration path. See the **[PubSub guide](https://github.com/OPCFoundation/UA-.NETStandard/blob/part14pubsub/Docs/PubSub.md)** and the **[2.0.x migration guide](https://github.com/OPCFoundation/UA-.NETStandard/blob/part14pubsub/Docs/migrate/2.0.x/pubsub.md)**. **Encodings & transports.** Both wire encodings are implemented in full — **UADP** (key/delta/event/keepalive, RawData, chunked, signed+encrypted) and **JSON** (verbose/compact, single-message, metadata; migrated from `Newtonsoft.Json` to `System.Text.Json`) — across **UDP** (uni/multi/broadcast + discovery), **MQTT** (3.1.1/5.0, retained metadata, TLS), and a from-scratch **DTLS 1.3** secured datagram transport (`opc.dtls://`) implemented on the .NET BCL crypto primitives (ECDHE, HelloRetryRequest cookies, certificate auth, AEAD record protection, HKDF key schedule), wired through `AddUdpTransport().WithDtls(...)`. Details in [Transports](https://github.com/OPCFoundation/UA-.NETStandard/blob/part14pubsub/Docs/PubSub.md#transports) and [Encodings](https://github.com/OPCFoundation/UA-.NETStandard/blob/part14pubsub/Docs/PubSub.md#encodings). A raw **Ethernet (Layer 2)** transport (`opc.eth://`, EtherType `0xB62C`, optional 802.1Q VLAN) carries UADP NetworkMessages directly in Ethernet II frames with no IP/UDP, via `AddEthTransport()` (`.WithPcap()` for cross-platform capture). See [Ethernet transport](https://github.com/OPCFoundation/UA-.NETStandard/blob/part14pubsub/Docs/PubSub.md#ethernet--uadp-opceth). **Runtime schema generation.** A new schema subsystem (`Opc.Ua.Core.Schema`, `Opc.Ua.PubSub.Schema`) generates **XSD**, **OPC Binary (BSD)**, and **JSON Schema** for OPC UA data types at runtime — including PubSub NetworkMessage/DataSet message schemas — driven from the type system and source-generated metadata (no reflection; NativeAOT/trim-safe). It is consumable from the client, server, and PubSub stacks. See the **[Schema generation guide](https://github.com/OPCFoundation/UA-.NETStandard/blob/part14pubsub/Docs/SchemaGeneration.md)**. **Security, fail-closed.** Message-level security is wired end-to-end through `IPubSubSecurityWrapperResolver`: publishers are fail-closed (a secured group with no key source throws rather than emitting plaintext) and subscribers enforce per-reader inbound security. It includes AES-CTR (128/256) policies with HMAC-SHA-256, a deterministic 96-bit nonce with a messages-per-key cap, a monotonic sliding replay window, and a Security Key Service (SKS) pull client + in-memory server with SecurityGroups and key rotation. Two independent security assessments (IEC 62443-4-2 × OPC UA Part 2/4/14, plus a Microsoft SDL/SFI delta pass) drove remediation of all actionable findings — including orphaned message security, chunked-frame security bypass, unauthenticated Action invocation, pre-auth reassembly DoS, and DTLS hardening. See [Security](https://github.com/OPCFoundation/UA-.NETStandard/blob/part14pubsub/Docs/PubSub.md#security) and [SKS](https://github.com/OPCFoundation/UA-.NETStandard/blob/part14pubsub/Docs/PubSub.md#security-key-service-sks). **Server-side & high availability.** The runtime can optionally surface through a standard in-process OPC UA address space (`Opc.Ua.PubSub.Server`) with configuration methods, per-component diagnostics, the full PubSubState model, KeepAlive and MessageReceiveTimeout. Pluggable configuration/runtime-state stores, an id allocator, and HA runtime-state providers with failover support running publishers/subscribers in a distributed system. See [Server-side address space](https://github.com/OPCFoundation/UA-.NETStandard/blob/part14pubsub/Docs/PubSub.md#server-side-address-space) and [High availability](https://github.com/OPCFoundation/UA-.NETStandard/blob/part14pubsub/Docs/PubSub.md#high-availability-state-providers). **External-server adapter (bridge) with hot-reload.** A new `Opc.Ua.PubSub.Adapter` binds PubSub publishers, subscribers, and Action responders to an **external** OPC UA server over `ManagedSession` — cyclic Read or subscription-backed sources, browse-path node mapping, and metadata that resolves/retries and re-emits on model-change events. Adapter and PubSub configuration **hot-reload incrementally** (only changed writers/readers/responders are rewired; unchanged sessions are reused), driven by `IPubSubConfigurationStore.Changed` and `IOptionsMonitor`, with a pluggable change-feed source (e.g. etcd). See [Binding PubSub to an external server](https://github.com/OPCFoundation/UA-.NETStandard/blob/part14pubsub/Docs/PubSub.md#binding-pubsub-to-an-external-opc-ua-server-client-session-adapters). **Samples, packaging & quality.** One combined sample, `ConsoleReferencePubSubClient`, demonstrates publisher, subscriber, and external-server modes on `Host.CreateApplicationBuilder` with full fluent/DI wiring; all libraries publish **NativeAOT with zero IL2026/IL3050 warnings** ([Native AOT](https://github.com/OPCFoundation/UA-.NETStandard/blob/part14pubsub/Docs/PubSub.md#native-aot), [DI](https://github.com/OPCFoundation/UA-.NETStandard/blob/part14pubsub/Docs/DependencyInjection.md)). The change ships comprehensive NUnit/integration suites and a libFuzzer harness, maintains ≥80% coverage on the new libraries, and is documented end-to-end ([What's new in 2.0](https://github.com/OPCFoundation/UA-.NETStandard/blob/part14pubsub/Docs/WhatsNewIn2.0.md)).
