Fix structure subtyping across dependency ModelDesign boundaries (#4335)
# Description The model source generator crashed whenever a `ModelDesign` declared a structure that subtypes a structure from **another** design file (`MODELGEN003` with a `NullReferenceException`), and the cross-assembly `[assembly: ModelDependency]` flow failed even earlier with `The BaseType reference ... is not the expected type: DataTypeDesign`. Structure inheritance across model boundaries — the primary use case of companion-spec layering — could not be source-generated at all. Three root causes, all in the dependency-loading path of the validator: 1. **Dependency design files were never linked.** They load with `validateDictionary: false`, so their `DataTypeDesign`s kept `BasicDataType` at the enum default (`Boolean`) and their fields' `DataTypeNode` stayed `null`. `BinarySchemaGenerator`'s inherited-field merge then dereferenced the null `DataTypeNode`, and `XmlSchemaGenerator` / `DataTypeGenerator` silently emitted `xs:boolean` / `bool` from the default classification. 2. **Dependencies that import the target crashed at load.** Each generation group receives every design file of the compilation as a dependency, including downstream models that import the group's target — those loaded *before* the target they import and failed resolving their `BaseType`. This produced the confusing `AdditionalFiles`-order-dependent failure modes. 3. **The payload flow never reached ModelDesign targets.** `ModelCompilation` supplied `referencedDependencies` only to the NodeSet2 pass, never to the design-file pass, and payload-materialised data types lacked the classification and field links needed to serve as base types of local structures. Changes: - `ModelDesignValidator.ValidateModel` loads dependencies in two phases around the target: upstream models first (topological, referenced models before their referrers), then the target, then models that import the target. - A new `LinkDependencyDataTypes` pass classifies dependency data types (`IsStructure` / `IsEnumeration` / `BasicDataType`) and resolves field `DataTypeNode` / `Parent` best effort. It runs for payload-imported declarations and upstream design-file dependencies before target validation, and for downstream dependencies after they load. NodeSet2 dependencies are excluded — `NodeSetToModelDesign` already links and classifies them with its own semantics. - Payloads for models that are backed by a design file in the compilation are skipped — the explicit file is authoritative (previously, importing both crashed with duplicate symbolic ids). - Payload-materialised data types honor the payload's `IsEnumeration` flag. - The design-file `GenerateCode` pass now receives the referenced assemblies' dependency payloads (`ModelCompilation` + new optional `referencedDependencies` parameter). - `docs/ModelDependencies.md` updated accordingly. Tests (all verified to fail with the exact reported errors before the fix): - `CrossModelStructureSubtypeTests` (Core, 6 tests): the issue's minimal repro end to end — asserting the emitted `.bsd` carries inherited fields with correct types and `SourceType`, the `.xsd` extends the dependency structure (not `xs:boolean`), and the generated C# derives correctly — plus the reversed target/dependency order, both payload flows at generation and validator level, and a three-level chain (target → payload structure → design-file structure). - `CrossModelStructureSubtypeGeneratorTests` (Roslyn driver, 3 tests): both `AdditionalFiles` orderings compiling the generated output, and the full cross-assembly flow (producer assembly generated from the upstream design; consumer resolves the base structure from the reference's payload without re-emitting it). Verified locally on net10.0: `Opc.Ua.SourceGeneration.Core.Tests` 3786 passed, `Opc.Ua.SourceGeneration.Tests` 135 passed, `Opc.Ua.SourceGeneration.Stack.Tests` 94 passed; 0-warning Release builds of `Opc.Ua.SourceGeneration.Core` (all TFMs incl. netstandard2.0), both Roslyn generator variants, Stack and Tester. This unblocks the `[NodeManager]` migration of the DataTypes workshop sample (OPCFoundation/UA-.NETStandard-Samples#757). ## Related Issues - Fixes #4332 ## Checklist _Put an `x` in the boxes that apply.

Source generator: typed NodeSet method signatures and referenced model accessors (#4124)
**Stack 2/5** — base #4123. Part of the #4096 split; see #4096 for the overall picture. > Review after #4123. The diff shown against `master` will include #4123 until that merges. ## What this is Source generator only; no runtime library changes. ## Contents - **Typed NodeSet method signatures.** A method imported from a NodeSet now gets a typed signature. Methods that share a declared signature are grouped onto one generated `MethodType`, named after its owner when the plain name would collide, so two unrelated `Execute` methods no longer share a class. - **An override that keeps the signature it inherits keeps the declaration it overrides.** Pointing `MethodDeclarationNode` at the override itself made `MethodDeclarationId` self-referential. OPC 10000-4 lets a caller invoke a method with the NodeId of its declaration in the ObjectType *or any supertype*, and `MethodState.MethodDeclarationId` is what the server matches on, so `Call` stopped resolving and returned `Bad_MethodInvalid` for every alarm subtype. An override that genuinely changes its signature still becomes its own declaration. - **`StateNumbers` / `TransitionNumbers` were emitted empty for every NodeSet-sourced model**, because such children arrive as `VariableDesign` rather than `PropertyDesign` and were filtered out. Any companion model built from a NodeSet was writing `StateNumber = 0` on the wire — a Part 16 defect well beyond the models in this stack. The ModelDesign path is unchanged. - **Referenced models can contribute fluent accessors**, carried by a model dependency payload so a downstream model can extend an upstream one. ## Notes for the reviewer - `tests/Opc.Ua.SourceGeneration.Tests` is left at its `master` content here. Its new vendor-subtype test uses the Robotics NodeSet as its fixture, so it can only land with the Robotics change at the top of the stack (5/5). - `PumpInstanceNodeIdRegressionTests` gains six `InputArguments`/`OutputArguments` entries for argument-less standard condition methods. Typed method signatures materialise those properties from the `ConditionType` declaration even where the method takes none. That is a real deviation, pinned rather than hidden so it stays visible; it is worth a follow-up. ## Validation `dotnet build UA.slnx` — 0 errors. | Suite | Result | | --- | --- | | Opc.Ua.SourceGeneration.Core.Tests | 3739 / 0 | | Opc.Ua.SourceGeneration.Tests | 81 / 0 | | Opc.Ua.Di.Tests | 304 / 0 | | Opc.Ua.History.Tests | 506 / 0 | | Opc.Ua.Gds.Tests | 1095 / 0 | History and GDS are listed because they are what the method-declaration fix above is load-bearing for: without it they fail with 10 and 370 errors respectively. --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Copilot-Session: 8cbb8cd0-f0cb-4ab0-bea2-6202fbf69485 |

Remove SourceGenerator.Foundations, ship analyzers under Roslyn-versioned folders for VS2022 and VS2026, and validate the packages (#4120)
# Description The two OPC UA source generators were built on `SourceGenerator.Foundations` (SGF), whose only job was getting the generator's dependency closure loaded inside the compiler. It does so with a **process-wide, first-generator-wins `AppDomain.AssemblyResolve` hook backed by a non-concurrent `Dictionary` mutated from `AssemblyLoad` callbacks**. Concurrent compilations in a shared `VBCSCompiler` race it, which is the root cause of the intermittent clean-build failure: ``` CSC : error CS8784: Generator 'StackSourceGeneratorHoist' failed to initialize. ... Exception was of type 'FileNotFoundException' with message 'Could not load file or assembly 'SourceGenerator.Foundations.Contracts, Version=2.0.14.0, ...' ``` The repository already solves that problem deterministically — #4041 made the NuGet packages ship the full closure under `analyzers/dotnet/.../cs`, and `Directory.Build.targets` registers the same closure as `Analyzer` items for in-repo `ProjectReference` consumers. SGF was therefore pure liability and is removed. ## What changed **1. SourceGenerator.Foundations removed.** `ModelSourceGenerator` and `StackSourceGenerator` are plain `[Generator(LanguageNames.CSharp)] IIncrementalGenerator` implementations again. SGF's implicit crash handling is replaced by an explicit `SourceGenerator.Guard` that reports `MODELGEN003` / `STACKGEN003` and rethrows cancellation. Its logger sink was already dead code and is dropped. `Opc.Ua.SourceGeneration.Stack.dll` shrank from **18 MB** (embedded closure) to **29 KB**. **2. Analyzers now ship under Roslyn-versioned folders.** `analyzers/dotnet/roslyn4.14/cs` and `analyzers/dotnet/roslyn5.0/cs` instead of `analyzers/dotnet/cs`, driven by `roslyn.props` at the repository root, with new `*.Pack` projects owning the package identity. The versioned folder matters: a host older than the band **skips** the analyzer instead of loading it and failing inside generator initialization. **3. Dependencies flow automatically.** Both delivery paths discover the payload by globbing the generator's output directory, so adding a package to a generator's dependency tree requires **no** `.csproj`, `.targets`, `.nuspec` or validation-script edit. Verified by temporarily adding a `PackageReference` and watching it appear in the payload with no other file touched. ## Two Roslyn bands: VS2022 and VS2026 Analyzers ship twice, once per band. The .NET SDK loads the highest band its compiler supports and **silently skips** anything above it, so a single-band package leaves every consumer below that band with no diagnostics and no generated code. | Band | Built against | Loaded by | | --- | --- | --- | | `roslyn4.14` | `Microsoft.CodeAnalysis.CSharp 4.14.0` | Visual Studio 2022 17.14+ / .NET 9 SDK | | `roslyn5.0` | `Microsoft.CodeAnalysis.CSharp 5.0.0` | Visual Studio 2026 18.0+ / .NET 10 SDK | Getting this wrong is invisible, which is most of why it took three attempts. The rule: > An analyzer must reference the **lowest** `System.Collections.Immutable` / `System.Reflection.Metadata` across all hosts it claims to support, and must never ship them. .NET binds a reference *upward* but never downward. Every failure mode is a compiler **warning**: | Diagnostic | Cause | | --- | --- | | `CS9057` | Built against a newer Roslyn than the host, so it is skipped entirely | | `CS8784` | Loaded, then `MissingMethodException` - a shipped S.C.I bound a second `ImmutableArray<T>` | | `CS8032` | Analyzer instance could not be created | This PR first shipped a `roslyn4.8` band that **never loaded** - confirmed against a real Roslyn 4.8 compiler: ``` warning CS8784: Generator 'ModelSourceGenerator' failed to initialize ... MissingMethodException: Method not found: 'IncrementalValueProvider`1<ImmutableArray`1<!!0>> IncrementalValueProviderExtensions.Collect(IncrementalValuesProvider`1<!!0>)' ``` That band was removed, and **this is not a regression**: master had the same defect, pinned to Roslyn 4.14 while referencing `System.Collections.Immutable 10.0.0.0`, so no 4.x host ever worked there either. The band that landed instead is `4.14`, and it is nearly free: `Microsoft.CodeAnalysis 4.14` depends on the **same S.C.I 9.0.0 as 5.0.0** and its `csc` runs on `net9.0`. Both bands therefore share `$(RoslynRuntimeVersion)`, so `Opc.Ua.Types` and `Opc.Ua.SourceGeneration.Core` are compiled **once** and serve both; only the five Roslyn-referencing assemblies get a second build, each from a 12-line project that glob-links the primary sources and overrides `RoslynApiVersion`. Going lower still - 4.8 wants S.C.I 7.x - would mean rebuilding that whole closure, `Opc.Ua.Types` included, and remains out of scope. (`System.Collections.Immutable 7.0.0` also does not resolve in this repository: `NU1603`, 8.0.0 substituted.) **Nothing else in the repository exercises the down-level payload**, and since every failure is a warning, a broken band would ship silently - exactly as the 4.8 one did. So `validate-source-generator-packages.ps1` now restores a real `Microsoft.Net.Compilers.Toolset 4.14.0`, runs its `csc.dll` over the packed `roslyn4.14` payload, and asserts **both** that none of `CS9057`/`CS8784`/`CS8032`/`CS8034` is emitted **and** that `/reportanalyzer` lists the generator as having executed - silence alone would also pass if the generator were never handed to the compiler. The migration analyzer, whose payload comes from a hand-written nuspec rather than `SourceGeneratorPack.targets`, gets the same check plus a band/assembly manifest assertion. To stop the trap recurring, `Microsoft.CodeAnalysis*`, `System.Collections.Immutable` and `System.Reflection.Metadata` are excluded from both the package payload and the in-repo analyzer closure, and asserted against in the validation script. `roslyn.props` and `docs/DeveloperGuide.md` document what adding a band requires. ## The shipped package set is unchanged Evaluating `PackageId`/`IsPackable` across every project in `preview-pack.slnx` gives the **same 47 package ids** on `master` and on this branch, and a full Release build plus `dotnet pack --no-build` produces exactly those 47. Only the owning project changed: | Package | master | this PR | | --- | --- | --- | | `…Opc.Ua.SourceGeneration` | `Opc.Ua.SourceGeneration.csproj` | `Opc.Ua.SourceGeneration.Pack.csproj` | | `…Opc.Ua.SourceGeneration.Stack` | `Opc.Ua.SourceGeneration.Stack.csproj` | `Opc.Ua.SourceGeneration.Stack.Pack.csproj` | `.azurepipelines/expected-packages.txt` pins the expected set and the validation script fails when the packed output drifts. ## Two new package checks **`build/<PackageId>.props` naming.** NuGet only auto-imports that exact name, and the file declares every `CompilerVisibleProperty` / `CompilerVisibleItemMetadata` the model generator relies on. It was previously packed as `build/OPCFoundation.Opc.Ua.SourceGeneration.props`, which does **not** match the package id — so **no NuGet consumer ever imported it**, and every `ModelSourceGenerator*` property and `AdditionalFiles` metadata was silently invisible. In-repo projects were unaffected because they import it by relative path. **An end-to-end consumer that actually drives the generator.** The pre-existing clean-consumer check only proved the analyzer *loads*. `Test-SourceGeneratingConsumer` builds a standalone project that feeds a real NodeSet2 in as an `AdditionalFile`, pins a `ModelSourceGeneratorPrefix` that cannot be derived from the model, and references the emitted types from hand-written code. It deliberately does **not** import the props by path, so the package's auto-import is what is under test. Both checks were verified to fail against a package rebuilt with the misnamed props. ## CI: parallelism re-enabled `buildandtest.yml` pinned three `dotnet build` invocations to `/p:UseSharedCompilation=false` and `-maxcpucount:1`. `dotnet build` defaults to all logical processors, so `-maxcpucount:1` actively disabled parallelism. Both flags were introduced silently in unrelated PRs (`f358078b1`, `208c601b0`) and suppress exactly the conditions the SGF race needed — now structurally gone. Compilation is ~72 % of what that workflow executes (233 of 323 job-minutes in run `29916768976`), so the queue-independent `Build` step durations are the baseline: | Measurement | Baseline | | --- | --- | | `Build` step, 26 `test-*` jobs | mean 5.53 min, sum 143.9 min | | `build-linux-all-tfm` | 56.3 min | | `build-windows-all-tfm` | 32.5 min | `codeql-analysis.yml` keeps the flag — the CodeQL tracer requires it. ## Incidental fixes - `Microsoft.CodeAnalysis.CSharp` declares an exact `[version]` range on `Microsoft.CodeAnalysis.Common`, so with `CentralPackageTransitivePinningEnabled` the central pins must move in lockstep or restore fails with `NU1109`. They now derive from `$(RoslynApiVersionVS2026)`. - `MigrationGeneratorTests` created its generator driver without parse options — silently fine under Roslyn 4.14, `Inconsistent language versions` under 5.0. - The migration analyzer props injected `<Analyzer>` items by hand from `analyzers/dotnet/cs`; NuGet registers analyzers itself and selects the matching folder, so the injection was obsolete and would now force the wrong assembly to load. - Exception diagnostics reported `ex.StackTrace` (null for an exception that never left its throw site, and carrying neither type nor inner chain) — now `ex.ToString()` at all three call sites. - The pack guard tested the flattened assembly list, so it only fired when *no* variant produced output; it now checks each declared variant contributed assemblies. - `GeneratePackageOnBuild` is disabled for the generators; packing happens in CI or on an explicit `dotnet pack`. ## Note for reviewers **Building this repository requires a Roslyn 5.x host** (the .NET 10 SDK or Visual Studio 2026). That is already the documented prerequisite and every CI leg installs `10.0.x` last, but it is now a hard requirement. ## Related Issues _No tracking issue: this is a follow-up to the CS8784 clean-build failure reported against #4041, which fixed the packaged delivery path but left the in-repo project-reference path relying on the SGF resolver._ - Follow-up to #4041 ## Checklist _Put an `x` in the boxes that apply.

Add OPC UA ISA-95 Common Model and Job Control support (#4089)
# Description Adds first-class support for the OPC UA ISA-95 companion specifications: - OPC-10030 Common Model. - OPC-10031-4 Job Control V1. - OPC-10031-4 Job Control V2. The change introduces `Opc.Ua.ISA95`, `Opc.Ua.ISA95.Client`, and `Opc.Ua.ISA95.Server`, together with a NativeAOT-compatible minimal server sample and comprehensive tests. ## Highlights - Compiles the three canonical NodeSets and identifier mapping CSV files through the source generator. - Adds NodeSet identifier mapping validation, typed method arguments/results, companion event records, and generated method argument nodes. - Provides typed Common Model builders with normative relationships and an injectable `GeoSpatialLocationType` provider. - Implements lossless V1/V2 Job Control providers over a shared version-neutral store, including state paths, status events, comments, response queries, catalog changes, and cohesive DI registration. - Adds subtype-aware typed clients, standalone encodeable registration, `IIsa95ClientFactory`, and V2 status-event streaming. - Adds the `MinimalIsa95Server` sample, package documentation, and an ISA-95 guide with conformance and HA guidance. - Tracks typed RSL/GPOS integration as follow-up issue #4095. ## Validation - `Opc.Ua.ISA95.Tests`: 137/137 passed on `net10.0` and `net48`. - Source-generator suites: 81/81 model, 90/90 stack, 3718 passed / 8 skipped core. - `EventRecordFieldReaders` feedback tests: 6/6 on `net10.0` and `net48`. - `EventRecordFieldReaders` changed-method patch coverage: 100% line coverage (36/36) and 100% branch coverage (22/22). - `Opc.Ua.ISA95`, `.Client`, and `.Server` build across all configured target frameworks without new diagnostics. - Cobertura line coverage: 88.08% model, 90.04% client, 91.19% server. - NativeAOT sample publishes and passes a live typed V2 Store/status-event validation. - The ISA-95 NativeAOT smoke test passes in the source-generated native test executable. - OPC UA KB NodeSet validation reports zero errors for Common, V1, and V2. The broader NativeAOT executable still reports unrelated existing GDS and complex-type test failures; the ISA-95-specific native test passes. ## Node state generator fixes Generating method arguments inline for imported nodesets regressed every model that already emits `InputArguments` / `OutputArguments` child node factories: - The inline block ran before the child factories. `MethodState.CreateOrReplaceInputArguments` keeps the property that was assigned first, so the child carrying the well-known NodeId was dropped and a NodeId-less placeholder remained in the address space. This broke browsing (reference descriptions without a target) and made method arguments unreachable at their well-known NodeIds. - The `MethodDeclarationId` fallback keyed on an autogenerated display name redirected every declared method of the standard address space to its own NodeId, which made method calls fail. The inline block is now emitted after the child factories and reduced to a value assignment when a child factory exists. The value is only re-emitted when an argument references a namespace other than OPC UA, because the value of an imported property is the verbatim XML of the source nodeset whose namespace indices do not survive the import. The `MethodDeclarationId` fallback is restricted to declarations without a resolvable NodeId. The generated OPC UA address space is byte-identical to `master` again. ## Related Issues - Fixes #4088 - Follow-up: #4095 |

Source generator: support compiled companion models and safe NodeState writes (#4063)
## Summary Combines the compiled companion-model support from #4062 with the NodeState emission fixes already in this PR. The model source generator can now consume compiled companion `NodeSet2` models more reliably, while generated factories consistently target base `NodeState` members even when a generated subclass shadows them. ## Changes ### Compiled companion NodeSets - Add `OpcUaStateTypeIndex` and wire it through `ModelSourceGenerator` / `ModelCompilation` so standard (`ns=0`) node-state and method-state class names are resolved from referenced `Opc.Ua.Core(.Types)` metadata. - Add the model-generation-scoped `StandardMethodStateFallback`, which degrades an unresolved standard typed `*MethodState` reference to `global::Opc.Ua.MethodState` only when the type is neither available in the compilation nor declared by the current generation pass. - Keep declaration names outside the reference-only fallback policy, propagate fallback state through the logical execution context, reuse the immutable availability index, and use named incremental-generator inputs instead of deep `Left` / `Right` chains. - Escape generated fluent-builder XML documentation where browse names can contain XML-sensitive characters. ### Safe NodeState factory emission - Declare one base-typed `global::Opc.Ua.NodeState nodeState = state;` local per generated factory. - Use `nodeState` for base-member reads and writes to `NodeId`, `SymbolicName`, `BrowseName`, `DisplayName`, `Description`, `WriteMask`, `UserWriteMask`, `AccessRestrictions`, `ReleaseStatus`, `Categories`, `Specification` and `IsPartOfTypeHierarchy`. - Base-qualify the optional-child `previousNodeId` read, NodeId comparison, and existing-child NodeId update. - `global::`-qualify emitted `NodeId` / `ExpandedNodeId` namespace prefixes to avoid namespace collisions. ### Supporting updates - Expose `Opc.Ua.Types` internals to `Opc.Ua.Core.Encoders.Tests`. - Update generator assertions and add focused fallback regression coverage. ## Why Compiled companion models can instantiate standard types whose curated Core implementation does not expose the conventionally named typed method-state class. The scoped fallback lets those models generate without weakening the Stack generator or masking classes emitted by the current model. Separately, generated subclasses can shadow base `NodeState` properties with strongly typed `new` properties. Routing base attributes through a `NodeState`-typed local guarantees initialization reaches the intended base member while keeping generated code smaller and clearer than repeated casts. ## Validation - Full `Opc.Ua.SourceGeneration.Core.Tests` on net10.0: **3718 passed / 8 skipped / 0 failed**. - Combined focused generator coverage on net48: **21 passed / 0 failed**. - Full `Opc.Ua.SourceGeneration.Tests`: **68 passed / 0 failed**. - Full `Opc.Ua.SourceGeneration.Stack.Tests`: **90 passed / 0 failed**. ## Context This PR supersedes #4062 and contains both source-generator change sets. The companion-model fallback remains the scoped interim workaround tracked by #4060; a future upstream name-resolution step can remove it. These changes also feed the experimental data-encodings work in #4007. --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> |
