Marc Schier	0374e19121	Add MachineTool, WMTP, GMS and CranesHoists companions (#4765) ... # Description _Describe the changes here to communicate to the maintainers why they should accept this pull request. By default - this will become the Commit message after merging and thus define history._ Add provider-backed MachineTool, bundled WMTP, GMS and CranesHoists companions using the existing Machinery/MachineVision fluent, DI and typed-client approach. **The PR is open/non-draft by user choice. Current head `ecc4a7d6ca3e8004cf28ab54da605da302d026bf` is mergeable and has 108 successful checks, six intentionally skipped checks, zero failures and zero pending checks. All five primary workflows completed successfully at that exact head.** | Family | Released specification/model | Packaging | | --- | --- | --- | | MachineTool | OPC 40501-1, 1.02.0 | Model, Server, Client and MCP; normal root versions | | WMTP | OPC 40505, 1.0.0 | Bundled in MachineTool; distinct CLR/wire namespace and independent WMTP-only hosting | | GMS | OPC 40210 reference 1.0.1, normative model 1.0.0 | Model, Server, Client and MCP; normal root versions | | CranesHoists | OPC 40020-1, 1.00 | Model, Server, Client and MCP; all four plus Debug variants forced preview | There are **12 new packable projects**. No separate WMTP package/profile/guide, root version bump, tag, release or package publication is included. Mandatory instance structure is the default; selected optional features require explicit providers. The implementation reuses Machinery results/jobs/files/ProcessValues and Robotics topology, including retained MachineTool Production, defined GMS jobs/parts, modern ISA95/Machinery jobs, shared-owner hosting and isolated instances alongside MachineVision. Runtime and integration fixes preserve raw quality/timestamps, coherent acquisition, namespace ownership, accepted-configuration state, borrowed-resource lifetime, session/node/file cleanup, terminal-value publication, event propagation and endpoint-aware capability publication. Firmware/licence transfer means provider acceptance, not installation/activation. Cancellation does not silently abort another caller's operation. The later upstream MCP expansion is integrated without losing either family set or its default-off privileged/live execution policy. ### Conformance and scope Canonical model inputs are pinned to UA-Nodeset revision `96a08945425d0295edb3607d2a38f6841ef44046`. **GMS upstream exception:** [Annex A.1](https://reference.opcfoundation.org/specs/OPC-40210/annex-a) makes the released NodeSet normative, but §12.3.2.7 requires undefined `GMS_ProductionStatisticsType`. Inherited statistics and defined jobs/parts are implemented without inventing a standard type/NodeId; the complete GMS Production facet is withheld. The requirement ledger records **102 positively evidenced CU rows, 96 directly negative-tested rows and six explicit negative-evidence limitations**. All 648 test-class/name/TRX links were independently resolved to passing cases. The six limitations concern Stacklight, retained legacy PowerOnDuration, Machinery PowerOnDuration, WorkingUnit, Obligation and MaintenanceMode. They are not claims that every invalid-input or hardware-control behavior was tested. The undefined GMS requirement is outside the 102 defined CUs. No external certification claim is made. Retained baseline complete-assembly line coverage, with generated code retained and no source exclusions: | Family | Model | Server | Client | | --- | ---: | ---: | ---: | | MachineTool/WMTP | 83.80% | 91.98% | 84.74% | | GMS | 95.51% | 90.63% | 88.38% | | CranesHoists | 92.76% | 94.45% | 92.24% | These nine measurements predate the later focused review fixes and merges; they are not relabelled as new `ecc4a7d6c` percentages. The current head's separate CI code-coverage check succeeded. No new exclusions or threshold relaxations were introduced. ## Related Issues - Fixes [#4764](https://github.com/OPCFoundation/UA-.NETStandard/issues/4764), the implementation/design and acceptance tracker. ## Checklist _Put an `x` in the boxes that apply.

Marc Schier	15d0ce7bd5	Implement OPC UA Part 10 Programs (#4789) ... # Description Implement OPC UA Part 10 Programs across `Opc.Ua.Core`/`Core.Types`, `Opc.Ua.Server`, and `Opc.Ua.Client`, reusing the existing state-machine, source-generation, node-management, auditing, and streaming-subscription infrastructure. - Add asynchronous provider-backed execution, standard controls, internal/autonomous transitions, generation checks, and nested-state activation/resumption. - Add checked creation/adoption, vendor Create adapters, deletion, recycling and instance limits, auto-delete, DI, and direct-construction paths. - Maintain ProgramDiagnostic2 and retained final results; publish captured intermediate results and concrete transition/audit events with access controls. - Add generated SDK models/proxies, typed client discovery and reads, event streams, and subscribe-before-call readiness handling. - Add unit, connected client/server, generated Annex A-style model, and NativeAOT coverage. Document usage and migration in `docs/Programs.md` and related guides. ### Compatibility and design decisions The linked Part 10 document is v1.05.00; namespace-zero definitions remain aligned with 1.05.07. Documentation distinguishes normative requirements from conflicting specification text and SDK conventions. - Correct state numbers to Halted=11, Ready=12, Running=13, Suspended=14. Generated subtypes retain inherited namespace-zero state/transition identifiers. - Managed Reset is Halted-to-Ready only. Preserve the existing low-level Reset-from-Suspended behavior for compatibility. - Preserve UInt32 limit types; use `UInt32.MaxValue` as a documented SDK unlimited convention. RecycleCount overflow reports BadOutOfRange without stopping unlimited execution. - In-memory default with injectable providers. Durable recovery, distributed execution/failover, and a production Annex A download engine are excluded. ## Checklist _Put an `x` in the boxes that apply.

romanett	9b034f8291	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.
