# Description
V2 subscription engine feature parity round to make the classic engine
eligible for deprecation. Splits the test surface so the classic and V2
engines can evolve independently, ports the gaps the classic-engine
integration tests had been exercising, and lands the public V2 API
additions needed to close them.
- Splits `Tests/Opc.Ua.Subscriptions.Tests` into a classic
(`Opc.Ua.Subscriptions.Classic.Tests`) and a V2
(`Opc.Ua.Subscriptions.Tests`) project to shrink CI time and let the two
engines diverge cleanly.
- Adds the V2 public-surface gaps required by the test ports
(`Subscription.ServerId` on the class, `SetSubscriptionDurableAsync`,
`SendInitialValuesOnTransfer`, unified `OnSubscriptionStateChangedAsync`
handler callback, per-item `ConditionRefreshAsync`, fluent
`LoadSubscriptionsAsync(Stream, …)` and `Subscription.Snapshot()` /
`RestoreAsync()` for save/load + transfer).
- Lands handler-centric design (no `PublishingStopped` property handlers
maintain derived state); always-sequential per-subscription delivery
documented + tested.
- **Adds short and long haul stability tests for the V2 `ManagedSession`
+ subscription engine. Closes #3744** (see "Issue #3744 Haul tests"
below).
- **Migrates SubscriptionStateSnapshot / MonitoredItemStateSnapshot to
`[DataType]` source-generator codecs**.
- `SubscriptionDurableV2Tests.cs` 5 V2 ports of the classic durable test
patterns.
- `V2FollowUpCoverageTests.cs` handler state-change callback, fluent
stream-based `LoadSubscriptionsAsync`, `SendInitialValuesOnTransfer`,
snapshot edge cases (empty / `DataChangeFilter` round-trip / concurrent
mutation).
- `SubscriptionFailoverV2Tests.cs` forced channel-break with and without
`WithTransferSubscriptionsOnRecreate`.
- `MonitoredItemConditionRefreshLiveV2Tests.cs` ΓÇö live
`ConditionRefresh` against the reference server's event source; asserts
`RefreshStart` / `RefreshEnd` events flow through the handler.
## Fixes
- #3744 Haul tests (V2 ManagedSession + subscription engine)
`Tests/Opc.Ua.Sessions.Tests/ManagedSessionStabilityTest.cs` adds the
short/long haul coverage requested by
[#3744](https://github.com/OPCFoundation/UA-.NETStandard/issues/3744)
plus the bonus fault-injection variant:
| Test | Duration | Category | Purpose |
|---|---|---|---|
| `ShortHaulManagedSessionV2Async` | 2 minutes | `ManagedSessionHaul`
(`[Explicit]`) | Quick local sanity check of the V2 monotonicity
contract. |
| `LongHaulManagedSessionV2Async` | 90 minutes (configurable via
`TEST_DURATION_MINUTES`) | `ManagedSessionHaul` (`[Explicit]`) |
Long-running V2 stability + monotonicity. |
| `LongHaulManagedSessionWithFaultInjectionV2Async` | 90 minutes
(configurable) + fault every `FAULT_INJECTION_INTERVAL_SECONDS` (default
60s) | `ManagedSessionHaul` (`[Explicit]`) | **Bonus** ΓÇö force-closes
the subscriber transport channel periodically; verifies V2 manager
transfers/recreates the subscription and continues monotonic delivery
across reconnects. |
**Pattern.** A writer `ManagedSession` increments a `uint32` counter and
writes it into `Scalar_Static_Mass_UInt32_UInt32_00` every 250ms. A
subscriber `ManagedSession` runs a V2 subscription with a single
monitored item on the same node. `MonotonicCounterHandler` asserts each
received sample is *strictly greater than* the previous one. V2
`ISubscriptionNotificationHandler` per-subscription ordering guarantee.
Skipped values (sampling rate < write rate) are tolerated; duplicates
and reorderings are violations.
Complete implementation of **OPC UA Part 9 ΓÇö Alarms & Conditions** for
both server and client, **OPC UA Part 16 ΓÇö State Machines** (generic
extensible client + server API), and the supporting infrastructure
(source-generated event records, source-generated ObjectType proxies,
`IAsyncEnumerable` streaming subscriptions, address-space model change
tracking, per-node `INodeCache` invalidation, unified DI integration).
### Server-side (Part 9 complete)
- **`AlarmConditionState`** ΓÇö every Part 9 method wired automatically
in `OnAfterCreate`: `Silence`, `Suppress`/`Suppress2`,
`Unsuppress`/`Unsuppress2`, `RemoveFromService`/`RemoveFromService2`,
`PlaceInService`/`PlaceInService2`, `Reset`/`Reset2`,
`GetGroupMemberships`. Each method generates the spec-mandated audit
event and supports an optional veto-delegate hook.
- **Latched alarms** ΓÇö `ActiveState` reflects real process state;
`LatchedState` persists until explicit `Reset` (with full precondition
validation).
- **Re-alarming** ΓÇö
`ProcessReAlarm`/`ResetReAlarmRepeatCount`/`IsReAlarmEnabled` helpers
(opt-in, no hidden timer).
- **Audible alarms** ΓÇö `UpdateAudibleState` for
`AudibleEnabled`/`AudibleSound`/`SilenceState` lifecycle.
- **Suppression + groups** ΓÇö `AlarmGroup`, `AlarmSuppressionEngine`
(with first-in-group), `AlarmRateTracker` (for `AlarmMetricsType`).
- **Spec-compliance fixes** ΓÇö `SuppressedOrShelved` now includes
`OutOfServiceState`; `GetRetainState` includes `LatchedState`;
`EffectiveDisplayName` composition includes `OutOfServiceState` +
`LatchedState`.
### Client-side Part 9 API
- **`AlarmClient`** ΓÇö typed Part 9 operations. Each method delegates
to the matching source-generated `*TypeClient` proxy
(`ConditionTypeClient`, `AcknowledgeableConditionTypeClient`,
`AlarmConditionTypeClient`, `DialogConditionTypeClient`,
`ShelvedStateMachineTypeClient`) ΓÇö one source of truth for every
method NodeId.
- **Interface hierarchy** — `IConditionOperations` →
`IAcknowledgeableConditionOperations` → `IAlarmOperations` +
`IDialogConditionOperations`.
- **Source-generated event records** ΓÇö new `EventRecordGenerator`
(alongside `ObjectTypeProxyGenerator`) emits `{Type}TypeRecord` per OPC
UA event type: `ConditionTypeRecord` →
`AcknowledgeableConditionTypeRecord` → `AlarmConditionTypeRecord` →
`LimitAlarmTypeRecord`/`ExclusiveLimitAlarmTypeRecord`/… all the way
to vendor subtypes. **Vendor alarm types get records automatically.**
- **`AlarmEventDecoder`** ΓÇö decodes `EventNotification.Fields` into
the most-specific generated record.
- **`AlarmEventFilterBuilder`** ΓÇö fluent builder for Part 9
`EventFilter`s.
- **`ISession.GetAlarmClient(telemetry)`** convenience extension.
### Part 16 state machines (generic, extensible)
- **Client**: extension methods on the source-generated
`StateMachineTypeClient` / `FiniteStateMachineTypeClient` ΓÇö
`GetCurrentStateAsync`, `ObserveFiniteTransitionsAsync`
(`IAsyncEnumerable<FiniteStateSnapshot>`), `WaitForStateAsync`,
`GetAvailableStatesAsync` / `GetAvailableTransitionsAsync`. **Vendor
proxies inherit the API automatically** through the generated
inheritance chain.
- **Server**: `StateMachineBuilder` (fluent: `AddState` /
`AddTransition` / `OnCause` / validation) +
`FluentFiniteStateMachineState` ΓÇö declare a Part 16 state machine
without subclassing the abstract base.
- **Alarms alignment**: `AlarmClient.GetShelvingStateAsync` /
`ObserveShelvingTransitionsAsync` surface the API for every alarm's
`ShelvingState` child.
### IAsyncEnumerable streaming subscription
- **`IStreamingSubscription`** with
`SubscribeDataChangesAsync`/`SubscribeEventsAsync` returning
`IAsyncEnumerable<T>` (Channel-backed).
- **`ManagedSession.DefaultStreaming`** ΓÇö lazy shared subscription;
disposed with the session.
- **Helpers** ΓÇö `TakeUntilAsync`, `WithTimeoutAsync`, `TakeAsync`,
`BufferedAsync` for state-machine waits and bounded observation windows.
- **`AlarmStreamExtensions`** ΓÇö
`SubscribeAlarmsAsync`/`SubscribeConditionsAsync`/`SubscribeDialogsAsync`
returning the source-generated record types.
### Address-space model change tracking
- **Server**: `RaiseGeneralModelChangeEvent` on both `CustomNodeManager`
and `AsyncCustomNodeManager`; `ModelChangeAggregator` (in
`Opc.Ua.Server.NodeManager`, used by every node manager) batches changes
per service call; **auto-emit** from `CreateNode`/`DeleteNode` (opt-out
via `ModelChangeEmissionEnabled = false`).
- **Client**: `IModelChangeTracker` subscribes to
`BaseModelChangeEventType` via the streaming subscription, decodes
`ModelChangeStructureDataType` payloads, invalidates the `INodeCache`
per-node.
- **`INodeCache.InvalidateNode(NodeId)`** ΓÇö new interface member (true
per-node eviction in `NodeCache`).
- **`ManagedSession.EnableModelChangeTrackingAsync()`** +
`ManagedSessionOptions.ModelChangeTracking` +
`ManagedSessionBuilder.WithModelChangeTracking()` fluent method.
### Dependency Injection integration
- **`services.AddOpcUa().AddClient(...).AddAlarms()`** ΓÇö registers
`AlarmClientFactory` so DI-hosted apps can resolve a Part 9 client per
session without `new`-ing one manually.
- Cross-link added to the unified DI surface (`AddServer` / `AddClient`
/ `AddComplexTypes` / `AddGdsServer` / `AddLdsServer` /
`AddWotConServer`).
### Quickstart server modernization
- `Quickstarts.Servers/Alarms/AlarmNodeManager.cs` ported to
`AsyncCustomNodeManager` and demonstrates the new `AlarmGroup` +
`AlarmSuppressionEngine` end-to-end via a writable `MaintenanceMode`
boolean that suppresses every member alarm.
### Documentation
- New: `Docs/AlarmsAndConditions.md`, `Docs/StreamingSubscription.md`,
`Docs/ModelChangeTracking.md`, `Docs/StateMachines.md` ΓÇö full
developer guides.
- Updated: `Docs/DependencyInjection.md` (`AddAlarms()` row + section),
`Docs/README.md` index, `Docs/MigrationGuide.md` (Part 9 / Part 16 /
model change tracking sections covering behavior changes + breaking API
surface).
- Sample: `Applications/ConsoleReferenceClient/AlarmClientSample.cs`.
Prepares the repository for a 2.0 release: bumps every version reference
from 1.6 to 2.0, and lands the migration guide describing the 1.5.378 →
2.0 upgrade path. The 1.6 line never shipped, so this is a straight
rename with no historical 1.6 migration content to preserve.
The PR is split into two commits:
1. **`Bump version to 2.0 (next release is a major version change)`** —
version metadata, NuGet metadata, the side documentation, and the
migration agent file.
2. **`[Docs] Close 19 audit gaps in 1.5.378 to 2.0 migration guide`** —
adds and reorganizes `Docs/MigrationGuide.md` to close every gap from a
rigorous code-review audit of the 1.5.378 → 2.0 breaking-change surface.
### Version bump (commit 1)
- `version.json`: `1.6-preview` → `2.0-preview`
- `common.props`: `<VersionPrefix>1.6</VersionPrefix>` →
`<VersionPrefix>2.0</VersionPrefix>`
- `nuget/Opc.Ua.nuspec` and `nuget/Opc.Ua.Symbols.nuspec`: `1.6.0` →
`2.0.0`
- `README.md`: "New in 1.6" → "New in 2.0"
- `Docs/ComplexTypes.md`, `Docs/Observability.md`, `Docs/Sessions.md`:
1.6 → 2.0 mentions
- Renames `.github/agents/opcua-v16-migration.agent.md` →
`.github/agents/opcua-v20-migration.agent.md` and updates the agent
metadata (name, description, trigger phrases, version table)
- `UA.slnx`: solution-items reference updated to the new agent filename
-
`Tools/Opc.Ua.SourceGeneration.Core/Generators/ObjectTypeProxyGenerator.cs`:
two v16 → v20 comment fixes
### Migration guide (commit 2)
Closes 19 gaps from an audit comparing `master378` (1.5.378) with
`master` (2.0). Adds a new top-level **Package, Target Framework and
Dependency Changes** section covering the new `Opc.Ua.Core.Types` and
`Opc.Ua.Security.Certificates` packages, the `LibTypesTargetFrameworks`
netstandard2.0 drop, the NuGet dependency additions/removals, and the
residual Newtonsoft.Json dependency in `Opc.Ua.PubSub`.
In-place additions:
- new H4 for `INodeManager3` under Node States
- `Session.Call` `Variant.From` worked example
- new H3 `Subscriptions and Transports` with H4 verdicts for Durable
subscriptions (source-breaking), PubSub (no source break) and Reverse
connect (no source break)
- new H3 `Telemetry and Logging` covering `ITelemetryContext`
constructor-injection patterns
- `in DataValue` async copy-to-local pattern
- UNSAFE / SAFE pair for `WithPoolNotifications` pooling
- using-alias example for classic vs V2 `SubscriptionOptions`
- "Silent regression" callout for `OnAfterCreate`
- numbered lifecycle ordering for
`ApplicationConfiguration.CertificateManager`
Corrections:
- clarifies that the `SessionReconnectHandler` `[Obsolete]` is still
present in 2.0 (not withdrawn);
- clarifies that the source-generated `ServerCapability` constants vs
the `ServerCapabilityInfo` registry type are distinct;
- disambiguates `ReconnectPolicyOptions` (DTO) from `ReconnectPolicy`
(runtime).
Adds an "Automate the migration" pointer to the forthcoming
`Opc.Ua.CodeFixers` analyzer package, which mechanizes 17 of the
patterns covered in this guide. The analyzer is published in a follow-up
PR.
Drive the solution to zero warnings / zero errors with analyzers on,
promote the consistently-fixed rules to error, and lock in coverage
on the only line of new logic.
* Add WoT Connectivity (OPC 10100-1) libraries and tests
Implements the OPC UA WoT Connectivity companion specification (OPC 10100-1, `WoT Connectivity for OPC UA`) through four new projects under the unified Opc.Ua.WotCon prefix:
* Opc.Ua.WotCon - source-generated model from the official WotConnection.xml + WotConnection.csv design files (NodeStates, NodeIds, ObjectType client proxies including WoTAssetFileTypeClient : FileTypeClient).
* Opc.Ua.WotCon.Server - WotConnectivityNodeManager (AsyncCustomNodeManager subclass), factory, DI options. Provider model split into IWotAssetProvider (per-asset Read/Write/Observe/InvokeAction) and IWotAssetDiscoveryProvider (server-level Discover/Test/CreateForEndpoint per spec sec. 6.3.4-6). System.Text.Json TD parser with AOT-safe JsonSerializerContext. Property mapper per spec table 14, action mapper per sec. 6.3.9. WotAssetFileManager enforces only OpenFileMode Read (1) and Write|EraseExisting (6) per spec sec. 6.3.10 and drives CloseAndUpdate materialisation + persistence.
* Opc.Ua.WotCon.Client - WotConnectivityClient and WotAssetClient compose the generated proxies (no inheritance). Extension methods on FileTypeClient / WoTAssetFileTypeClient add chunked upload/download and the Open(Write|EraseExisting) -> Write* -> CloseAndUpdate flow, extending the existing FileSystem API without subclassing.
* Opc.Ua.WotCon.Tests - NUnit suite (28 passing tests) covering TD parsing, property and action mappers, and the SimulatedWotAssetProvider/SimulatedWotDiscoveryProvider which serve as canonical examples of the provider contract.
Two refactors that together reshape how the stack tier is laid out:
1. Rename `Opc.Ua` project to `Opc.Ua.Core.Types`
* Stack/Opc.Ua/ -> Stack/Opc.Ua.Core.Types/ (git mv preserves history)
* Opc.Ua.csproj -> Opc.Ua.Core.Types.csproj
* AssemblyName : `Opc.Ua` -> `Opc.Ua.Core.Types`
* PackageId : `OPCFoundation.NetStandard.Opc.Ua` ->
`OPCFoundation.NetStandard.Opc.Ua.Core.Types`
* RootNamespace : kept as `Opc.Ua`
* StackGeneration.cs assembly-name switch updated; the renamed
assembly still produces `StackGenerationType.Models`.
* The `OPCFoundation.NetStandard.Opc.Ua` name now belongs solely to
the roll-up meta-package (nuget/Opc.Ua.nuspec); the meta-package's
former self-dependency is replaced with the new
`.Core.Types` package, and `.Symbols.nuspec` gains the
matching `.Core.Types.Debug` debug-symbol dependency.
2. Move `Opc.Ua.Security.Certificates` from Libraries/ to Stack/
It is a stack-tier dependency consumed by Opc.Ua.Core, not a
higher-level library extension, so it now sits alongside the other
stack projects.
Both refactors update the same set of cross-cutting infrastructure:
- UA.slnx, UA Core Library.slnx, Applications/ConsoleReferenceServer/Dockerfile
- .azurepipelines/signlist{Debug,Release}.txt
- ProjectReferences across Stack/, Libraries/, Tests/, Fuzzing/
- Tests/Opc.Ua.SourceGeneration.Stack.Tests/StackGenerationAssemblyTests.cs
- Docs/PlatformBuild.md and .github/copilot-instructions.md (new
Core.Types package listed)
Verification
* dotnet build UA.slnx -c Debug -- succeeded, 0 errors
* StackGenerationAssemblyTests : 5 passed
* Opc.Ua.SourceGeneration.Tests : 40 passed
* Opc.Ua.SourceGeneration.Core.Tests : 3514 passed, 8 skipped
* Opc.Ua.Core.Tests (Stack filter) : 1982 passed, 80 skipped
* Opc.Ua.Security.Certificates.Tests : 239 passed
* New certificate and secrete abstraction with certificate infrastructure and certificate/secret stores.
* leak testing for certificate resources to validate new ref counting in every test assembly
* Migration guide updated and documentation added for all
* Remove IDisposable from Nodestate and UserIdentity.
* UserCertificateTokenHandler now just points into certificate registry/stores, no dispose required
* Fix CA2000 warnings and cleanup of other diagnostics, increase warning levels in .editorconfig
Add interop test agent
The new stack-pass ObjectMethodProxyGenerator emits proxies that derive
from Opc.Ua.ObjectTypeClient and reference Session.MessageContext.NamespaceUris.
Neither type exists in the in-memory test compilation, which only references
Opc.Ua.Types.dll. Moving ObjectTypeClient to Opc.Ua.Types would cascade ISessionClient,
IClientBase, ITransportChannel and the generated service interfaces with it, so the
type stays in Opc.Ua.Core and we add a minimal stub to OpcUaCoreStubs instead.
Wire Microsoft.Extensions.Options 10.0.5 + DependencyInjection.Abstractions 10.0.5 into Directory.Packages.props and the Gds.Client.Common project to enable upcoming options-driven configuration work.
Modernize Opc.Ua.Gds.Client.Common (DI, options, interfaces, async dispose)
Split validator load/validate; split DesignFileCollection Targets/Dependencies
ModelDesignValidator.LoadNodes now skips ValidateDictionary when a model is loaded purely as a dependency. The flag is plumbed through LoadModelDesign and LoadDesignFile; the dep loop in ValidateModel passes false, the primary target passes true. This lets callers supply unrelated or reverse dependencies (deps that import the target) without triggering premature validation failures.
DesignFileCollection exposes Targets + Dependencies; generators and tests updated. MergeNamespace preserves FilePath across PublicationDate-based replacement so later loads can still find the source file. Tester simplified to treat every other xml/csv pair as a dependency of each target.

Generate stack and application code using source generators
Change built in types to readonly structs
Update localized text implementation to use JSON text serializer
Status code with symbolic names
Immutable node ids
No boxing for all built in types <= 8 bytes in Variant.
Split user identity token and token handling via token handler
Add migration guide for breaking changes
This change adds a **new Opc.Ua.Types** nuget that contains core types that do not rely on generated code. Why the name? Because almost all code that was in the Types subfolder is part of it, and because we do not want to change the name of the Opc.Ua.Core nuget/assembly because code relies on it. Any other name like base or bootstrap felt out of place due to the current structure already defining the name "types". Key design is to depend on only a small set of libraries with limited transitive dependencies, that includes hashcode, logging.abstraction, and for non standard20 builds System.Text.Json (needed for localizedText mul parsing). Also, key is to support .netstd 2.0 to support source generators and to allow removal of EEC_SUPPORT defines by removing std2.0 from core and all libraries.
The changes are mostly restructuring, and thus small but contain some key changes:
- **Status code** struct now comes with a Symbol field, which is used to carry symbols in case the code is not generated. Currently (until generated) the status code struct must be manually created with a symbol or the ToSymbolicId extension must be called in the core project. Future will generate Status code constants just like NodeId that contain the symbol which also removes the reflection-based lookup. Several tests needed to be adjusted as they checked the status code symbol strings instead of the code.
- **Core identifiers** are copied as they were needed for code to compile, that includes attributes, a subset of status codes and node identifiers. These will never change so no need to generate them.
- The types folder now contains **encoders**, except for json which is still in core. Once the json encoder is ported to system.text.json it will also be included and Newtonsoft.Json dropped as dependency (-> #3329).
- Since types relies on **IOperationContext** and **ISystemContext**, and these export IUserIdentity which relies on crypto, these were split and extended in core with ISessionOperationContext and ISessionSystemContext, which mean changes to ServerSystemContext and introduction of SessionOperationContext and SessionSystemContext classes that extend OperationContext and SystemContext. Some runtime checks in the server are therefore needed to get at the session and auth info, however, those are anyway optional fields and are not on the critical paths, and thus a type check is in order (and was done in the past already, but against OperationContext class).
- **Manifest resources** are now split between Core (nodeset zip, some generated resoures) and Types (built in bsd/xsds). This needs to be revisited later if the bsd/xsd need to be regenerated during type generation. Note that the embedded resource names changed as a result. Since these are only used internally and do not constitute public API this feels reasonable vs duplication of resources in 2 assemblies.
- Reflection however now needs to load not just the built in **encodeables** from Opc.Ua.Types assembly, but also the generated encodeables from Opc.Ua.Core assembly. For this a new helper Utils method was added to get the Core assembly when linked against Opc.Ua.Core otherwise null.
- Whatever utils methods needed to be split out into the new Opc.Ua.Types assembly, they are now in **CoreUtils** static class in Opc.Ua.Types, and Utils.xxxx forwards to them to ensure minimal changes. Later we would want to obsolete them in favor of CoreUtils, although it might make sense to split them again into domain specific utilities, such as networking, files, etc

The goal is to reduce the overall number of builds, stop using end of life platforms in the build pipeline and to support
build of future/deprecated build targets in a custom build step, which is also triggered weekly in the ci builds.
In addition:
- added a doc which describes the release and versioning strategy of this project
- produce the Nuget packges with .NET 8 assemblies.
- produce a Docker build based on a .NET 8 based container.
- add custom test targets to test outdated platforms. Need a manual step to enable for VS or command line.
- bug fixes: the latest move to an alternate crypto library for Bouncy Castle, which is only used for the GDS support and .NET Framework 4.6.2./netstandard2.0, revealed already a few issues which were previously not found.
- only .NET8/.NET6/.NET Framework 4.8 are tested in Pull requests. Remaining builds in weekly scheduled builds.
