Marc Schier 5899354441 Clarify documentation, migration guidance, and SDK selection (#4823)
# Description

Remove stock phrasing and correct misleading or inconsistent technical
documentation. The initial two passes covered 367 Markdown files,
followed by an interactive review of 169 editorial flags. The U5
interpretation originally deferred in that review has since received the
upstream Mantis answer recorded by #4843; remaining server/spec
follow-ups stay explicit in the CTT log.

- Correct package responsibilities, migration steps, API names,
ownership, protocol descriptions and links. Keep bundled migration
guides synchronized. Preserve historical conclusions as historical
records with separate re-check notes.
- Provide at least two rendered TOC levels throughout `docs/`. Convert
appropriate architecture figures to Mermaid without changing code
examples, transcripts or historical quotations.
- Address the October 19 feedback with concrete setup/migration
instructions, corrected certificate paths and PubSub names, shorter
repeated caveats, consistent XML comments, and a full review of the
Concepts guide. Retain #4839's API corrections.
- Integrate #4841's runtime/performance guidance and review
incoming/recent prose. Preserve dated measurements rather than claiming
new benchmark runs; clarify allocation ratios, startup-only processor
settings, JIT warm-up and the benchmark commit's scope. Missing raw
measurement artifacts and repeat ranges remain tracked by #4842.
- Merge master through `e8c5d800a` in `32c6394b7`. Resolve the CTT log
conflict using the updated Mantis states and OPC answers, retaining
historical framing and re-checks for C28/C32/C43.
- Address the latest naming/index feedback in `adb5bf693`: rename the
guides to `docs/WotCon.md` and `docs/WotNodeSetConversion.md`; move the
provider and DataType-declaration contracts into the conversion guide
and remove `docs/WoT.md`. Rename `samples/DI` to `samples/Di` and
`samples/Isa95` to `samples/ISA95`. Add content-index READMEs to Di,
FluentApi, ISA95, Lds and PubSub; update solution entries, project
references, Docker/CI paths, test fixture paths and documentation links
with exact casing.

**WoT guide scope.** This branch retains the detailed conversion guide
that #4758 had replaced with an anchor stub. Conversion limits, verified
document sets, preservation rules and provider ownership now live
together in `WotNodeSetConversion.md`; binding/runtime guidance remains
in `WotBindings.md` and `WotCon.md`. The design-rationale/test-ledger
prose was shortened, the oversized argument-table cell moved into its
section, and existing anchors preserved.

**SDK policy is a separate, explicit user-directed change.**
`global.json` sets a stable minimum of `10.0.400`, `rollForward:
latestMajor`, and `allowPrerelease: false`. Newer major SDKs are
permitted; CI's explicit SDK pins are unchanged. README, GettingStarted,
DeveloperGuide and Recycling instructions reflect the possible analyzer
differences. The image-contract regression fix accepts compatible stable
SDK images instead of requiring exact equality with the floor.

The latest four rename/index threads are resolved after publication.
Three older threads remain open: universal obsolete-removal timing,
unconditional nonce-strength wording, and a blanket Vision NativeAOT
claim. Existing implementation/evidence constraints are explained in
their inline replies. The two-level TOCs remain as requested.

## Validation

- `git diff --check` and staged diff checks: passed. The untouched
upstream AutoID NodeSet retains its provenance bytes, including two
existing license-header trailing spaces.
- `.\.azurepipelines\validate-migration-plugin.ps1`: passed; 15 bundled
migration documents and manifests synchronized.
- Documentation/path validation: **101** documents retain two rendered
TOC levels (**2,228** entries), with idempotent formatting. **52** new
relative links and their anchors passed exact-case checks. No tracked
references to the old guide/sample paths remain. Both relocated
provider-contract sections are preserved in the destination.
- `dotnet sln UA.slnx list`: passed; shows the renamed Di/ISA95 projects
and the existing FluentApi/Lds/PubSub projects. Updated solution and
pump ProjectReference paths also passed exact-case existence checks.
- Latest focused commands, run from the repository root:

```powershell
# Passed: 61 channel send-order and reconnect tests.
dotnet test tests\Opc.Ua.Core.Tests\Opc.Ua.Core.Tests.csproj -p:CustomTestTarget=net10.0 --filter 'FullyQualifiedName~UaSCBinaryChannelSendOrderTests|FullyQualifiedName~TcpReconnectKeyAgreementTests' --verbosity minimal

# Passed: 5 pump datasheet tests; builds the renamed pump sample.
dotnet test tests\Opc.Ua.Di.Tests\Opc.Ua.Di.Tests.csproj -p:CustomTestTarget=net10.0 --filter 'FullyQualifiedName~PumpDatasheetConformanceTests' --verbosity minimal

# Passed: 4 repository NodeSet path/round-trip tests, including the moved pump models.
dotnet test tests\Opc.Ua.Types.Tests\Opc.Ua.Types.Tests.csproj -p:CustomTestTarget=net10.0 --filter 'FullyQualifiedName~RepositorySourceSurvivesSerializedLinkedPartitionsAsync' --verbosity minimal

# Passed: build, zero warnings/errors.
dotnet build samples\ISA95\MinimalIsa95Server\MinimalIsa95Server.csproj -p:CustomTestTarget=net10.0 -f net10.0 --verbosity minimal

# Passed: dependent sample-test project build, zero warnings/errors.
dotnet build tests\Opc.Ua.WotCon.Samples.Tests\Opc.Ua.WotCon.Samples.Tests.csproj -p:CustomTestTarget=net10.0 -f net10.0 --verbosity minimal
```

Earlier focused integration checks passed 2,620 tests across AutoID,
event queues/scheduling, source generation, MCP/package profiles and
WoT. Both reviewed Mermaid diagrams rendered locally without network
access. These checks are not a full solution run.

The full solution has **not** been rerun for this review. Earlier
`dotnet test UA.slnx -p:CustomTestTarget=net10.0 --verbosity quiet` did
not pass: three AOT projects rejected VSTest and 20 Vision tests failed
during graphics initialization with `OutOfMemoryException`. Remaining
long-running tests were stopped at the user's request. A focused Vision
rerun passed 558 tests and reproduced those 20 failures. The earlier
`dotnet test UA.slnx -p:CustomTestTarget=net48 --verbosity quiet` was
blocked by the former SDK pin and was not retried after the policy
change. The user approved proceeding with those limitations documented;
current remote CI is not claimed green.

## Related Issues

- Follow-up #4842 tracks the requested 2.0.2+ benchmark/tuning and
diagnostic-tool documentation refresh. #4841 supplies documentation and
earlier results, not all newly requested measurements.
- #4758 explains the conversion guide's earlier consolidation; the
current provider contracts are now consolidated into
`WotNodeSetConversion.md`.
- #4839 supplies the reviewed API corrections; #4843 supplies the
updated CTT issue record.
- The original prose cleanup and SDK policy were user-requested without
a source issue. No new runtime architecture is introduced by these
documentation edits.

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.

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.

Copilot e78c648295 Images CI: publish samples once natively and stop compiling under QEMU (#4679)
# Description

Images CI took 45–100 min per image. The arm64 half of every
`linux/amd64,linux/arm64` build ran `dotnet restore` and `dotnet
publish` in an arm64 SDK container under QEMU. For `refserver`, publish
took 8 min natively for amd64 and 92 min emulated for arm64. On top of
that, every one of the 10 matrix legs recompiled the whole stack.

The output is framework-dependent portable IL, so the compile is now
done once, natively. The image legs only copy files onto the
per-platform runtime base image.

### Dockerfiles (all 10)
- **SDK stage runs on the build platform.** The `build` stage is pinned
to `--platform=$BUILDPLATFORM`. `-p:UseAppHost=false` keeps an x64 app
host out of the arm64 image.
- **New `prebuilt` stage.** It is chosen with a global `ARG
PUBLISH_SOURCE`, which defaults to `build`. Local `docker build` and the
`docker-compose` files are unchanged.
  ```dockerfile
  FROM scratch AS prebuilt
  ARG PUBLISH_DIR=artifacts/docker/publish
  COPY ${PUBLISH_DIR}/ /app/publish/

  FROM ${PUBLISH_SOURCE} AS publish
  ```
- **Pump: final-stage `RUN`s moved to a native stage.** The `sed` on
`openssl.cnf` and the `mkdir`/`chown`/`chmod` steps now run in a
`$BUILDPLATFORM` `layout` stage. The final stage copies `/layout/` to
`/`, so `/app` and `/diag` keep the `$APP_UID:0` owner and `g=u` mode
they had before. `openssl.cnf` therefore comes from the build-platform
base image. It is a plain config file, so it is expected to match
between architectures.

### `docker-image.yml`
- **Single image list.** The image list lives once, in `env.IMAGES`
(image, project, Dockerfile). `discover` emits it as the matrix.
- **New `publish-samples` job.** It runs `dotnet publish` for each
sample sequentially, so shared libraries compile once. It uses the same
options and NBGV version properties as the Dockerfiles and uploads the
output as the `docker-publish` artifact.
- **`build-and-push-image` legs.** Each leg:
  - downloads the artifact;
- builds with `PUBLISH_SOURCE=prebuilt` and
`PUBLISH_DIR=artifacts/docker/publish/<image>`;
  - no longer uses `setup-qemu-action`;
  - is named `build-and-push-image (<image>)`.
- **`images summary`.** It now also fails when `publish-samples` fails.

### Docs
- `ContainerReferenceServer.md` describes the publish-once / copy-only
flow and the build arguments.
- `DeveloperGuide.md` mentions the `publish-samples` job in the Images
CI section.

Expected: one native publish of about 7 min, then 10 parallel
copy-and-push legs of a few minutes each. Not yet confirmed on CI: the
sandbox could not pull MCR base images, so the prebuilt multi-platform
builds were checked against a Debian-based stand-in base, and the
build-from-source path was not built.

Copilot d525bc3f28 Bound reconnect cleanup and organize samples by domain (#4276)
# Description

This PR fixes bounded ManagedSession reconnect cleanup and reorganizes
the sample applications into domain-focused folders.

## Reconnect cleanup

- Bounds reconnect integration cleanup with independent 30-second close
and dispose limits.
- Sends `CloseSession` through the awaited transport request path during
`Session.DisposeAsync`.
- Preserves explicit `Session.CloseAsync` behavior that waits for or
cancels outstanding publish requests.
- Covers the disposal request path with a regression test.

## Sample organization

- `samples/OpenUsd`: `GeneratorServer`, `SiteCompositionServer`
- `samples/Redundancy`: `RedundantClient`, `RedundantServer`,
`RedundantPubSub`
- `samples/Isa95`: `MinimalIsa95Server`
- `samples/MinimalApi`: `MinimalBoilerServer`, `MinimalCalcServer`,
`MinimalClient`
- `samples/DI`: `PumpDeviceIntegrationServer`
- `samples/Lds`: `ConsoleLdsServer`
- `samples/Reference`: `ConsoleReferenceClient`,
`ConsoleReferenceServer`
- `samples/PubSub`: `ConsoleReferencePubSubClient`

`UA.slnx` now exposes the same requested domain groups. Project
references, tests, runtime sample probes, CI workflows, Dockerfiles,
Compose files, helper scripts, and documentation were updated to the new
paths. `samples/Robotics/MinimalRobotServer` remains under `Robotics`.

## Validation

- `dotnet build UA.slnx`
- 3 Redundancy short-haul sample tests
- 70 DI sample tests
- 914 OpenUSD tests
- 1 WotCon model-materialization test
- 137 AOT tests
- `docker compose config` for all 6 moved Redundancy Compose files
