Update NuGet dependencies and migrate tests to NUnit 5 (#4840)
# Description Update 55 NuGet dependencies to the latest stable releases available on 2026-10-19, preserving documented compatibility pins and framework-specific version bands. Existing OpenUSD prereleases remain unchanged because no newer releases are available. Migrate existing tests to NUnit 5: await asynchronous assertions, propagate async through helpers, handle nullable predicates, and replace obsolete `Order` attributes with sequencing dependencies. Sequencing dependencies use `AllowFailure = true`; filtering a dependent test also runs prerequisites. Adjust fixture-level parallelism where NUnit dependency scheduling requires it. Keep Roslyn API/runtime pins intact; select newer Immutable/Metadata runtime packages only for test and profiling hosts requiring them. Update the approved SDK pin to 10.0.402 across local, CI, and container builds. Document NUnit 5 conventions. |

Add Machine Vision Parts 1 and 2 (#4733)
# Description Implement the released [OPC 40100-1](https://reference.opcfoundation.org/specs/OPC-40100-1) and [OPC 40100-2](https://reference.opcfoundation.org/specs/OPC-40100-2) specifications with generated models, provider-backed runtimes, typed clients, MCP workflows, and DI/Machinery integration. - **Part 1 stays in `Opc.Ua.Vision`** and its client/server packages alongside the distinct Perception model. Provide control/acquisition state machines, jobs and synchronized steps, recipe/product/configuration/result management, file transfers, diagnostics, events, and conditions. - **Part 2 is in `Opc.Ua.MachineVision`, `.Client`, and `.Server`.** Provide asset categories, identification, image-handling aspects, health/maintenance data, topology, and transactional updates. The base Vision assemblies do not reference these optional packages; the Part 2 wire model does not depend on Part 1. - Preserve the release-pinned model bytes, wire namespaces and NodeIds. Perception types are in `Opc.Ua.Vision.Perception`; the AMCM generated namespace remains `Opc.Ua.Vision.MachineVision.AMCM`, and asset client/server extension namespaces remain `Opc.Ua.Vision.Client` and `Opc.Ua.Vision.Server`. - Use `AddOpcUaMachineVision` and `AddOpcUaMachineVisionAMCM` for model loading and factory registration. Each has node-collection, encodeable-factory-builder and node-state-factory-builder overloads. These short entry points delegate to the generated implementations; existing namespace-derived generated names remain available for compatibility. - Support multiple independent named systems/assets under one namespace-owning manager. Reuse injectable providers, file binding, bounded memory stores, optional transactional `IFileSystemProvider` persistence, state machines, telemetry and conformance infrastructure. - Keep one `docs/Vision.md` guide, titled `Machine Vision (OPC 40100-1 and OPC 40100-2)`, and one `Opc.Ua.Mcp.Vision` package. Include deterministic server/client samples. - Expose 17 Machine Vision MCP tools, including capabilities/status, bounded relationships and observation, complete small-file uploads/downloads, management, explicit control, conditions, and chunked transfers. Catalogue counts: 39 Vision-specific, 43 with connection tools, 81 Vision+Robotics, 155 Full. Every Machine Vision wire parameter has a schema description. **Compatibility and limits:** `AddVision()` remains Perception-only unless released parts are selected. Standalone Part 2 uses `AddVision().AddMachineVision()`; Machinery composition uses `AddVisionToMachinery()`. Existing tool defaults and command signatures are preserved. Observation owns and cleans up its subscription: 5 seconds/50 notifications by default, capped at 60 seconds/100 notifications. Complete-file tools are capped at 1 MiB; larger files use chunked transfers. Domain Error values remain distinct from UA service failures. **Versioning:** the seven Vision/MachineVision/MCP packages and their Debug variants follow the repository root version instead of being forced to preview. Vision.OpenUsd and its descendants remain preview-only. Development builds still inherit the root prerelease version. No release version, tag, release branch, publication policy, or feed promotion is changed. **Review actions:** all fourteen review threads have action/evidence replies and are resolved. Changes include the unified guide, Perception namespace, separate Part 2 packages and final naming, multi-system ownership explanation, interrupted-write cleanup, observer failure isolation, complete MCP parameter descriptions, and explicit package inventory. The preview-layout migration topic and the requested ReleaseProcess caveat were removed. The test Publish collector now retries recognized transient failures within one cancellation budget and propagates other exceptions. Commit |

Enable nullable reference types centrally; migrate all unset and annotations-only projects (#4700)
# Description Nullable reference types are now enabled once, in `common.props`, and every project in the repository builds warning-clean with them. **Configuration** - `<Nullable>enable</Nullable>` lives in `common.props`. All per-project `<Nullable>` settings are removed: 178 project files (enable, annotations, and the `disable` in the three Aot test projects). - 419 per-file `#nullable enable`/`restore` directives and the 4 `#nullable disable` directives are removed. - Kept on purpose: - The 5 `<auto-generated>` schema files (`UANodeSet.cs`, `UA Type Dictionary.cs`, `OPCBinarySchema.cs`, `SecuredApplication.cs`, `PInvokeHelper.cs`) keep `#nullable enable`. The compiler ignores the project setting in generated code, so the directive is required there. - `tests/Opc.Ua.Interop.LegacyPeer` keeps `disable`. It builds against the 1.5.378 packages and does not import the repository props. - `docs/DeveloperGuide.md` and `.github/copilot-instructions.md` now describe the central setting. **Migration** (the 43 unset and 13 annotations-only projects, roughly 10k diagnostics) - **Production code: annotated at the declarations.** Covers `tools/Opc.Ua.SourceGeneration.Core`, `src/Opc.Ua.Lds.Server` and the LDS sample. - Members, parameters and returns are nullable where null actually flows. - Null-check helpers carry `[NotNullWhen]` (`IsNull`, `IsValidXmlName`, `IsMethodTypeDesign`). - `CoreUtils.Format`, `Utils.Format`, `ITemplateWriter.WriteLine` take `params object?[]`. `Template.AddReplacement` takes `string?` (rendering already skips null replacements). - `IRegisteredServerStore.RegisterAsync` returns `Task<RegistrationEntry?>`: it returns null when a registration is removed. - Dereferences backed by an invariant (for example, the validated model) use `!`, so runtime behaviour is unchanged. - **Behavioural changes in production code** (small, deliberate): - `NodeSetToModelDesign` throws `InvalidOperationException` when the file is not a NodeSet. Before, it threw a NullReferenceException on the next line. - `ModelDesignValidator` starts its lookup tables empty instead of null. A redundant `if (m_nodes == null) return;` guard is gone. - **Test code: minimal annotations.** - `?` on values that can be null, `!` where the test asserts non-null. - `= null!` for fixture members assigned in SetUp. - `TryGetStructure<T>(out T? x)` where the inferred `T?` broke the `IEncodeable` constraint. - A few redundant `== null` checks on structs (`NodeId`, `ArrayOf<T>`) folded into the adjacent `IsNull`/`Count` checks. **Notes for reviewers** - The diff is large (~1,500 files) but almost entirely mechanical: `?`, `!` and directive removal. The non-annotation changes are listed above. - Known follow-up, not done here: `IModelDesign.Namespaces/TargetNamespace/NamespaceUris` stay non-nullable even though the validator returns null before it loads a dictionary. Making them nullable would ripple through every generator call site. ## Related Issues - Fixes #4439 ## Checklist - [ ] I have signed the [CLA](https://opcfoundation.org/license/cla/ContributorLicenseAgreementv1.0.pdf) and read the [CONTRIBUTING](https://github.com/OPCFoundation/UA-.NETStandard/blob/master/CONTRIBUTING.md) doc. - [ ] I have added tests that prove my fix is effective or that my feature works and increased code coverage. - [x] I have added all necessary documentation. - [x] I have verified that my changes do not introduce (new) build or analyzer warnings. - [ ] I ran **all** tests locally using the **UA.slnx** solution against at least .net **framework** and .net **10**, and all passed. - [ ] I fixed **all** failing and flaky tests in the CI pipelines and **all** CodeQL warnings. - [ ] I have addressed **all** PR feedback received. The "no new warnings" box covers net10.0 and net48: full non-incremental builds of `UA.slnx`, `tools/SourceGeneration.slnx`, `tools/MigrationAnalyzer.slnx` and the Aot test projects finished with 0 warnings and 0 errors under the repository's warnings-as-errors settings. net9.0 and net8.0 also had no nullable diagnostics, but they were not rebuilt after the final fixes. Tests have not been run locally yet. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

[Server] Add live NodeManager lifecycle support (#4094)
# Description Adds supported live add, reload, and remove lifecycle operations for NodeManager instances on a running server. The change introduces a DI-backed `INodeManagerLifecycle` service with direct `StandardServer` access, generation-aware registration handles, copy-on-write routing, transactional prepare/commit/rollback, runtime NodeSet convenience APIs, append-only namespace updates, model and semantic change notifications, additive-compatible complex type priming, and complete teardown behavior. Lifecycle publication is coordinated with requests, sessions, subscriptions, monitored items, continuation points, and shutdown so retired managers cannot remain reachable or be disposed while still in use. Compatible monitored items transfer to replacement generations without a transient bad status. Removed or incompatible Nodes publish `BadNodeIdUnknown` as required by OPC UA Part 4 section 5.8.4.1, retain their MonitoredItem identity, and automatically recover when a compatible Node with the same NodeId returns. Registration is documented end to end in the new [docs/NodeManagerRegistration.md](docs/NodeManagerRegistration.md), which covers compile-time, startup, and runtime registration together with the guarantees for MonitoredItems, Browse continuation points, namespace indexes, DataTypes, and change notifications. ## Review feedback addressed Interface surface reduced, as requested: - `INodeManagerMonitoredItemTracker` folded into `ISubscriptionMonitoredItemLifecycle`. - `INodeManagerMutationCoordinator` and the asynchronous MonitoredItem recovery entry point folded into `IDynamicNodeManagerHost`. - `ISessionClosingRegistry` folded into `IServerInternal`, then replaced by `ISession.IsClosing`. - `ISubscriptionDeletionRegistry` folded into `ISubscriptionManager`, then removed entirely. - `INodeManagerContinuationPointTracker` folded into `ISession`. - The synchronous recovery entry point kept on its own `ISyncNodeManagerMonitoredItemRecovery`, because `AddPredefinedNode` cannot await; it still routes through the asynchronous `INodeManagerMonitoredItemLifecycle` that `AsyncNodeManagerAdapter` exposes. - `IMonitoredItemLifecycle` renamed to `IDetachableMonitoredItem`. Reach into the Subscription area reduced to the minimum the feature needs: - The lifecycle feature itself leaves `SubscriptionManager` almost untouched: two guards that reject a request from a Session that is closing, on `CreateSubscription` and on `TransferSubscriptions`, because it would create state that is about to be torn down. The deletion claim registry, the session closing gates, the closed-session bookkeeping and the deletion restore paths introduced by earlier revisions are gone. Transferring a subscription away from a session that is closing stays allowed, since that is the recovery path the service exists for; the race that exposed is fixed by serialising source-queue closure with the transfer rather than by rejecting it. - Queueing is disabled again for a MonitoredItem with `QueueSize <= 1`, as before this PR. Without a queue the Client is served the last sampled value, so the missing-Node notification simply becomes that value; losing values is expected for a MonitoredItem without queuing. - What remains of the notification is one `DataValue` plus one bool in `DataChangeQueueHandler`, mirroring the existing overflow pair, which stops it being the value discarded when a configured queue is full. - `MonitoredItem` keeps its original publish path, its original queue creation and restore paths, its original triggering behaviour, and no per-epoch bookkeeping. - `IStoredMonitoredItem` carries `IsDeleted` and `IsDetached`, so a restored item reports the state it was stored with rather than one inferred from the last value's StatusCode. Other feedback: - Documented `HostedNodeManagerLifecycle`, `IDynamicNodeManagerHost`, `NodeManagerRoutingTable`, and the `RequestManager` validation and request scopes. - Renamed `ValidateMonitoredItemAsync` to `CanAttachMonitoredItemAsync` and `RestoreMonitoredItemAsync` to `RecoverMonitoredItemAsync`, so the lifecycle API no longer collides with the durable Subscription `RestoreMonitoredItem` path used at server startup. - Removed the `CustomNodeManager2` dependency from the synchronous MonitoredItem recovery path. - `DataChangeQueueHandler` is back to the two constructors 1.5.378 shipped, each taking an optional `TimeProvider`. - Session closing is a one-way latch, and the Session is removed even when teardown throws. - Documented what a custom NodeManager has to implement to take part in live lifecycle operations, and which NodeManager implements `INodeManagerReloadParticipant` today. ## Fixes found during review - The guard that stops a NodeManager lifecycle operation being started from inside a service handler never fired. It was backed by an `AsyncLocal` written inside `async ValidateRequestAsync`, which is invisible to the caller that awaited it, so a lifecycle call from a NodeManager callback waited for its own request and held the lifecycle semaphore forever. The mark is now applied by the service dispatcher, and the drain is bounded so no path can wedge the lifecycle permanently. - `ValidateRequestAsync` is no longer virtual. An override that rejected a request after calling `base` left it registered forever; subclasses now use `OnRequestValidatedAsync`, whose failures complete the request. - A MonitoredItem deleted and disposed while a reload was handing it to the replacement NodeManager could be attached anyway. The item now reserves itself for the hand-over and the transition takes it back if it was disposed meanwhile. - The Overflow bit is recorded and applied when the value is published, as the surrounding design does, rather than written into the value at enqueue time. - MonitoredItem cleanup for a Subscription being deleted no longer passes null entries to `DeleteMonitoredItemsAsync`. - Browse continuation points of a retired NodeManager are persisted and disposed outside the Session lock. ## Open review discussions Three threads are open, replied to and awaiting reviewer decisions: separating service-call dispatch from NodeManager handling in `MasterNodeManager` (tracked as #4098), the request-scoping shape in `StandardServer`, and how much of the async MonitoredItem service implementation should stay in `Subscription`. Issue #4102 records a specification ambiguity found while implementing the missing-Node notification: Part 4 §5.8.4.1 makes it mandatory, but the protected over-capacity queue entry §5.13.1.5 defines applies to `EventQueueOverflowEventType` only, so the specification does not say how it survives a full queue. ## Validation - Full `Opc.Ua.Server.Tests` on net10.0: 3,768 passed, 5 skipped. - Lifecycle, MonitoredItem, Subscription and continuation point suites: 185 passed on net10.0 and 75 on net48. - Server builds complete with zero warnings or errors. - Two failures are pre-existing and unrelated: `DurableDataValueQueueVerifyReferenceBatchingAsync` (flaky `BatchPersistor` file contention, passes in isolation on net10.0 and net48) and `ConfigureApplicationBuildsSharedClientAndServerConfigurationAsync` (fails on a clean tree with these changes stashed). ## Related Issues - Fixes #3993 - Follow-up tracked in #4098 |
