…19472) * Fix #12796: handle arrays of user-defined types in custom attributes Empty arrays of non-encodable types (classes, records, structs) in custom attributes now compile successfully by encoding them as System.Object[] per ECMA-335. Non-empty arrays of such types produce FS3887 instead of the internal error FS0192.

* Add LabelOps agentic workflows Two opt-in, label-gated workflows for automated PR maintenance: - labelops-pr-maintenance: scheduled every 3h, iterates open PRs carrying AI-Auto-Resolve-Conflicts or AI-Auto-Resolve-CI, shuffles for fairness seeded by GITHUB_RUN_ID, caps at 5 PRs per run. Per PR: triages CI first (pr-build-status skill), resolves conflicts second. Small mechanical CI fixes applied in-place with local verification. Proven flakes (flaky-test-detector ≥3 PRs) are delegated to the spinoff workflow. Unfixable CI escalates by adding AI-needs-CI-fix-input with a repro + up to 3 options. Labels are sticky — agent never removes any label. - labelops-flake-fix: workflow_dispatch-only spinoff, dispatched from the babysitter via safe-outputs.dispatch-workflow. Re-verifies the flake, reproduces with a 20-iteration loop, prefers determinism fix else quarantines. Scoped to tests/** and vsintegration/tests/**. Both workflows use protected-files: fallback-to-issue to prevent any .github/** modifications. Ship with schedule enabled; dry-run via workflow_dispatch recommended before relying on scheduled runs.

Update to 4.6.3 which matches SystemMemoryVersion in eng/Versions.props and is guaranteed to be in the NuGet cache since the compiler itself depends on it.

)" (#19701) This reverts commit ba48c78.

The expert-reviewer agent had 19 review dimensions and 4 analysis waves but zero instructions about posting the review to GitHub. Copilot would analyze thoroughly but never execute gh commands to create inline comments on the PR. Add Wave 5: Deliver Review as Inline Comments — mandatory final wave that instructs the agent to post findings via gh api as a review with inline comments at the correct file+line from the diff, deduplicate against existing reviews, and apply the AI-reviewed label.

* Fix Array.exists2 XML doc examples to use equal-length arrays Both examples used arrays of different lengths (2 vs 3 elements), which would cause ArgumentException at runtime. The documented 'Evaluates to false/true' results were therefore incorrect. Fixed by using equal-length input arrays that produce the stated results: - inputs2 = [| 1; 3 |] with inputs1 = [| 1; 2 |] evaluates to false (neither 1>1 nor 2>3) - inputs2 = [| 1; 3 |] with inputs1 = [| 1; 4 |] evaluates to true (4>3) * Add release notes for Array.exists2 doc fix Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> --------- Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com>

) * Add agentic state machine diagram generator workflow Weekly workflow that reads all .md agentic workflows in the repo, extracts triggers, labels, safe-outputs, handovers, and conditions, then renders a Mermaid diagram + tables in docs/state-machine.md. Outputs: - Summary table (workflow / trigger / reads / writes / key labels) - Mermaid stateDiagram showing full issue + PR lifecycle - Label dictionary (who applies, who reads, what it means) - Handover map (workflow A → workflow B, mechanism) Opens a PR to update the diagram. allowed-files: docs/** only. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Rewrite state machine generator with multi-diagram approach Applied: Mermaid stateDiagram-v2 best practices (composite states, choice nodes, direction LR, classDef styling, notes), Anthropic prompt guide (XML tags, role, concrete examples), Peli audit-workflows pattern. Key changes: - Multiple diagrams by dimension (issues, PRs, labels, handovers) instead of one giant unreadable diagram - Composite states for PR types (fork, non-fork, regression-test) - Change detection via source fingerprint comment - skip if unchanged - Diagram guidelines section teaching Mermaid techniques - Concrete example showing Issue Lifecycle structure - Screen-wide LR layout, max ~15 states per diagram - Label dictionary + handover map as tables (not diagrams) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Add actors, CI, incremental updates to state machine generator Actors: 👤 contributor, 👤 maintainer, 🤖 agent:<name>, ⚙️ CI, ⏰ scheduler Every diagram edge shows WHO performs the transition. CI is always present — PRs go through build/test, agents react to CI results. Never skip the CI step in diagrams. Incremental updates: read existing state-machine.md as starting point, update only sections affected by workflow changes. Minimal diffs. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Rewrite state machine generator: 173 → 75 lines Adversarial review by Opus 4.7 + 4.6 found 6 blocking issues. Generation test by Opus 4.7 produced excellent output but confirmed the prompt was overfit to current 3 workflows. Fixes applied: - Future-proof: agent discovers lifecycle groups from data, not hardcoded Issue/PR sections. Handles file/branch workflows (aw-auto-update) and meta-workflows (itself) without prompt changes. - Mermaid: cross-composite transitions go outside blocks (syntax fix). Removed broken example. No fake workflow names. - Fingerprint: sha256 content hash instead of file size. - Incremental: reads existing output, updates only changed sections. - Bloat: removed <context>, actor definitions, filler sentences. Cut from 173 to 75 lines — same capability. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

…/build/agentic-time behavior (#19680) * Add LabelOps PR security scan workflow Hourly text-only scan of external PRs. Reads diff, classifies risk into categories (build infra, compiler output, bootstrap, prompt injection, supply chain, scope mismatch), and labels accordingly. Never checks out or builds PR code.

Add a date filter to the labelops-pr-security-scan workflow so it silently skips any PR whose createdAt is before 2026-05-12T00:00:00Z. This avoids retroactively labeling/commenting on older PRs. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

…sages (#19730) * Parser: fix unexpected diagnostics in debug builds, improve error messages * Release notes

* Fix F# exception serialization to preserve fields

…ocs category (#19725) `Async.StartChild` is a mainstream way to kick off concurrent child work, so it belongs in the same docs section as `Async.StartChildAsTask` rather than under "Cancellation and Exceptions". This only changes the rendered docs grouping; no code or behavior impact.

check_release_notes runs via pull_request_target, so GitHub executes the workflow definition from the default branch (main). For bot-authored PRs such as Maestro/darc dependency updates (e.g. PR #20133), the run's GITHUB_TOKEN is capped and the issue-comment API returns HTTP 403 'Resource not accessible by integration', which failed the required check even though release-notes validation itself passed ('No release notes required'). Mark the 'Create or update comment' step with continue-on-error so posting the informational comment can never fail the check. The real gate (exit 1 when release notes are genuinely missing) is unchanged. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Creating a PR comment requires pull-requests: write, but #20081 reduced the token to pull-requests: read. Because the job runs via pull_request_target (GitHub executes the workflow from the default branch), this turned the required check red with HTTP 403 'Resource not accessible by integration' on any PR that needed to create (not update) the comment - e.g. the Maestro/darc PR #20133 targeting release/dev18.0 - even though release-notes validation itself passed.

The merge of the arcade update with the Central Package Management PR (#20084) left duplicated PackageReference entries in the runtime-dependencies ItemGroup, including an unterminated <PackageReference> tag that caused MSB4025 (project could not be loaded), failing every CI build job. Remove the stale versioned entries, keeping only the versionless CPM-style references. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

…M merge The merge that pulled the Central Package Management change (#20084) into this release/dev18.0-based branch left, in 12 project files, a duplicated block of the old versioned PackageReference entries above the new versionless CPM entries. NuGet restore failed with NU1504 (Duplicate 'PackageReference' items) across FSharp.Test.Utilities and the vsintegration projects, breaking every CI job. FSharpSuite.Tests.fsproj additionally had a duplicate <OutputType>.

The prior run had all fsharp-ci build jobs green; only 'Build Linux' failed when the test host was SIGKILL'd (exit code 137) after the agent hit 'Free memory is lower than 5%'. No test actually failed (failed: 0); the ComponentTests process was OOM-killed mid-run. This empty commit retriggers CI. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

…0-file guard) This maestro dependency PR (arcade 10.0.0-beta.26379.2 -> 26403.2) was accidentally contaminated by a 661-commit merge of origin/main, inflating the base<->head diff to ~5,867 files. The check_release_notes workflow (executed from the default branch) fails closed at >=3,000 changed files, before it can evaluate the NO_RELEASE_NOTES opt-out, so the check could never pass while the merge content remained in the PR diff. This additive commit resets the tree to release/dev18.0 + the arcade bump only (eng/Version.Details.props, eng/Version.Details.xml, global.json), so the PR's effective diff is the intended dependency update.

* Avoid leaking a MeterListener per Cache in DEBUG builds (#19995) * Avoid leaking a MeterListener per Cache in DEBUG builds In DEBUG builds, every Cache instance created a CacheMetrics.CacheMetricsListener, which starts a System.Diagnostics.Metrics.MeterListener registered in the process-global metrics registry. These were never disposed, so they accumulated for the lifetime of the process. Because every cache hit/miss/add publishes a measurement to all registered listeners, the per-operation cost grew linearly with the number of leaked listeners, so workloads that create many caches (for example repeated ParseAndCheckProject / per-file checks) slowed down steadily. Track the per-cache totals used by DebugDisplay directly, incrementing a small Stats object alongside the existing global Meter counters, instead of via a per-cache MeterListener. No listener is created, so nothing leaks, and DebugDisplay still works. The now-unused CacheMetrics.Hit/Miss/Add/Update/Eviction/EvictionFail helpers are replaced by a single recordMetric helper. * Address review: drop per-cache CacheMetricsListener and cacheId tag - Remove the CacheMetrics.CacheMetricsListener type. Its only per-cache use was the #if DEBUG debugListener each Cache created and never disposed, which was the leak this PR set out to fix. (majocha) - Drop the per-instance cacheId tag (and nextCacheId). Measurements now carry only the cache name, shrinking the payload published to any connected exporter and removing the per-instance filtering that was cacheId's only purpose. (majocha) - DebugDisplay and the cache tests read the existing name-aggregated stats via CacheMetrics.getTotalsByName / getRatioByName, populated by the single process-wide ListenToAll listener. No per-cache listener is created and no per-operation cost is added in any configuration, so there is no DEBUG-only overhead left to gate behind a separate directive. (T-Gro) - Overload-cache tests enable ListenToAll and snapshot totals before/after to stay scoped to their own compilation; FSharpChecker .CreateOverloadCacheMetricsListener is removed. * Update public SurfaceArea baseline after removing CacheMetricsListener CacheMetricsListener was a public type, so dropping it changes the recorded public surface. Remove its 10 entries from FSharp.Compiler.Service.SurfaceArea.netstandard20.bsl; the SurfaceArea test now passes. Also note the single-listener assumption the cache metric tests rely on. * Apply fantomas formatting to Caches.fs * Document why OverloadCacheTests is not parallelizable (global cache metrics state) --------- Co-authored-by: Tomas Grosup <Tomas.Grosup@gmail.com> * Bump FCSMinorVersion to 13 (keep main above 10.0.4xx servicing 43.12.400) (#20045) * Update dependencies from https://github.com/dotnet/msbuild build 20260708.3 (#20048) On relative base path root Microsoft.Build , Microsoft.Build.Framework , Microsoft.Build.Tasks.Core , Microsoft.Build.Utilities.Core From Version 18.10.0-preview-26357-08 -> To Version 18.10.0-preview-26358-03 Co-authored-by: dotnet-maestro[bot] <dotnet-maestro[bot]@users.noreply.github.com> * Update dependencies from https://github.com/dotnet/roslyn build 20260708.9 (#20049) On relative base path root Microsoft.CodeAnalysis , Microsoft.CodeAnalysis.Compilers , Microsoft.CodeAnalysis.CSharp , Microsoft.CodeAnalysis.EditorFeatures , Microsoft.CodeAnalysis.EditorFeatures.Text , Microsoft.CodeAnalysis.ExternalAccess.FSharp , Microsoft.CodeAnalysis.Features , Microsoft.VisualStudio.LanguageServices From Version 5.10.0-1.26357.6 -> To Version 5.10.0-1.26358.9 Co-authored-by: dotnet-maestro[bot] <dotnet-maestro[bot]@users.noreply.github.com> * Add ResetCompilerGeneratedNameState to compiler-generated name generators (#20017) Compiler-generated occurrence names (name@line-N) are allocated from process-wide counters on CompilerGlobalState that accumulate across compilations. When a warm checker re-emits the same project in-process, an unchanged closure therefore gets a different occurrence suffix than the previous emit, so consumers that align generated names across compilations (Edit-and-Continue delta emission, #19941) cannot match them. Add an internal ResetCompilerGeneratedNameState to NiceNameGenerator (clears the per-(name, file) occurrence counters), StableNiceNameGenerator (clears the cached stable names and the inner counters), and an aggregate on CompilerGlobalState that resets all three generators, restoring the fresh-process name layout. Callers must ensure no compilation is concurrently generating names. No in-tree caller yet; the consumer is the hot reload emit path in #19941. Covered by unit tests proving drift without reset, exact replay after reset, and that the stable-name cache itself is cleared. * Update dependencies from https://github.com/dotnet/msbuild build 20260709.10 (#20051) On relative base path root Microsoft.Build , Microsoft.Build.Framework , Microsoft.Build.Tasks.Core , Microsoft.Build.Utilities.Core From Version 18.10.0-preview-26358-03 -> To Version 18.10.0-1.26359.10 Co-authored-by: dotnet-maestro[bot] <dotnet-maestro[bot]@users.noreply.github.com> * [main] Update dependencies from dotnet/msbuild (#20055) * Update dependencies from https://github.com/dotnet/msbuild build 20260710.4 On relative base path root Microsoft.Build , Microsoft.Build.Framework , Microsoft.Build.Tasks.Core , Microsoft.Build.Utilities.Core From Version 18.10.0-1.26359.10 -> To Version 18.10.0-1.26360.4 * Update dependencies from https://github.com/dotnet/msbuild build 20260713.4 On relative base path root Microsoft.Build , Microsoft.Build.Framework , Microsoft.Build.Tasks.Core , Microsoft.Build.Utilities.Core From Version 18.10.0-1.26359.10 -> To Version 18.10.0-1.26363.4 * Update dependencies from https://github.com/dotnet/msbuild build 20260714.11 On relative base path root Microsoft.Build , Microsoft.Build.Framework , Microsoft.Build.Tasks.Core , Microsoft.Build.Utilities.Core From Version 18.10.0-1.26359.10 -> To Version 18.10.0-1.26364.11 * Update dependencies from https://github.com/dotnet/msbuild build 20260715.6 On relative base path root Microsoft.Build , Microsoft.Build.Framework , Microsoft.Build.Tasks.Core , Microsoft.Build.Utilities.Core From Version 18.10.0-1.26359.10 -> To Version 18.10.0-1.26365.6 * Update dependencies from https://github.com/dotnet/msbuild build 20260716.8 On relative base path root Microsoft.Build , Microsoft.Build.Framework , Microsoft.Build.Tasks.Core , Microsoft.Build.Utilities.Core From Version 18.10.0-1.26359.10 -> To Version 18.10.0-1.26366.8 * Update dependencies from https://github.com/dotnet/msbuild build 20260717.5 On relative base path root Microsoft.Build , Microsoft.Build.Framework , Microsoft.Build.Tasks.Core , Microsoft.Build.Utilities.Core From Version 18.10.0-1.26359.10 -> To Version 18.10.0-1.26367.5 * Update dependencies from https://github.com/dotnet/msbuild build 20260719.1 On relative base path root Microsoft.Build , Microsoft.Build.Framework , Microsoft.Build.Tasks.Core , Microsoft.Build.Utilities.Core From Version 18.10.0-1.26359.10 -> To Version 18.10.0-1.26369.1 * Update dependencies from https://github.com/dotnet/msbuild build 20260720.18 On relative base path root Microsoft.Build , Microsoft.Build.Framework , Microsoft.Build.Tasks.Core , Microsoft.Build.Utilities.Core From Version 18.10.0-1.26359.10 -> To Version 18.10.0-1.26370.18 --------- Co-authored-by: dotnet-maestro[bot] <dotnet-maestro[bot]@users.noreply.github.com> * [main] Update dependencies from dotnet/roslyn (#20052) * Update dependencies from https://github.com/dotnet/roslyn build 20260709.4 On relative base path root Microsoft.CodeAnalysis , Microsoft.CodeAnalysis.Compilers , Microsoft.CodeAnalysis.CSharp , Microsoft.CodeAnalysis.EditorFeatures , Microsoft.CodeAnalysis.EditorFeatures.Text , Microsoft.CodeAnalysis.ExternalAccess.FSharp , Microsoft.CodeAnalysis.Features , Microsoft.VisualStudio.LanguageServices From Version 5.10.0-1.26358.9 -> To Version 5.10.0-1.26359.4 * Fix NU1605 package downgrades from Roslyn 5.10.0-1.26359.4 bump The new Roslyn build adds a net472 dependency on Microsoft.VisualStudio.SDK 18.9.496-Preview and bumps its runtime deps to 10.0.8, causing package downgrade errors: - System.Collections.Immutable / System.Reflection.Metadata / System.Composition now required >= 10.0.8 (were pinned to 10.0.2) - VS interops (OLE/Shell/TextManager.Interop) required >= 18.9.438 - Microsoft.VisualStudio.Threading required >= 18.7.19 The three interop packages are decoupled from the shared shell package version since the VS SDK pins them newer than the other shell packages.

Two runtime-only breaks remained after the earlier NU1605/MSB3277 build-time fixes, both surfacing as a ReflectionTypeLoadException in the VsMocks MEF catalog that failed all ~1959 legacy VS unit tests: 1. Microsoft.VisualStudio.Platform.VSEditor is not pulled transitively, so it stayed pinned at 18.0.404-preview and its implementation types no longer bind against the newer Text.Internal 18.9.123 interfaces. Pin VSEditor to 18.9.123 to match. 2. Shell.15.0 18.9.x references Microsoft.VisualStudio.SolutionPersistence at runtime without declaring it as a NuGet dependency; deploy it next to the VS unit-test host (scoped to test projects to keep it out of the VSIX).

The legacy suite keeps only the tests that genuinely exercise Visual Studio integration. * Add Roslyn-format EnC CustomDebugInformation codec and portable PDB method CDI emission (#20018) * Add Roslyn-format EnC CustomDebugInformation codec and portable PDB method CDI emission Adds an internal AbstractIL module implementing, byte for byte, the three Portable PDB CustomDebugInformation blob formats Roslyn persists per method for Edit and Continue (EnC Local Slot Map, EnC Lambda and Closure Map, EnC State Machine State Map), with serializers, deserializers, a portable PDB read-back helper, and an occurrence-key packing helper for deterministic syntax-offset slots. Plumbs an optional methodCustomDebugInfoRows side channel through the IL binary writer options into the portable PDB generator so a compilation can attach CDI rows to named methods. Names that do not identify exactly one method row are dropped. All existing writer call sites pass an empty map, so emitted PDBs are byte-identical to before. No in-tree caller populates the map yet; the consumer is the F# hot reload work in #19941, following the same pattern as #20017 (land isolated, test-covered infrastructure first, wire the feature later). Tests: blob round-trips, Roslyn golden-byte encodings, cross-validation against CDI blobs emitted by a real Roslyn compilation, fail-closed occurrence-key packing (including an int32-overflow regression where a wrapped negative key previously escaped the bound check), and end-to-end synthetic PDB emission proving correct MethodDef parenting, zero rows for an empty map, and no rows for absent or ambiguous names. * Add stable synthesized-name replay infrastructure for hot reload (#20024) * Extract stable synthesized-name replay layer Add internal generated-name normalization and synthesized-name map replay support as a standalone slice. The new map state is side-channel based, all new compiler modules remain internal, and CompilerGlobalState preserves the existing no-map counter path while checking an accessor captured once per compiler state. Route existing IlxGen generated-name allocations through inert helper wrappers, add pure name-map and normalizer tests, add a normal compilation determinism guard over emitted generated names, and document the extracted seams in P5_REPORT.md. Verification: built FSharp.Compiler.Service, FSharp.Compiler.Service.Tests, FSharp.Compiler.ComponentTests, and FSharpSuite.Tests in Release; ran the migrated service test classes, the component determinism class, FSharpSuite DeterministicTests, and the FCS SurfaceArea class successfully. * Fix generated-name scope test in stable names slice * Validate hot reload generated names before classification * Format hot reload compiler sources Verified with the repository-wide Fantomas check. * Retry CI after Linux runner memory exhaustion * Make synthesized name snapshots deterministic * Fix #19457: lift CE constructs from plain let RHS in computation expressions (#19868) * Fix attribute resolution in recursive module/namespace scopes (#19744) * Correct StructLayout size emission for data-less struct unions (#19759) * Report FS3888 for generic attribute type abbreviations instead of FS0193 (#19915) * Move to .NET 11 (SDK, Arcade, product TargetFramework) (#20080) Upgrade the repo to build on .NET 11 and target net11.0, plus the adaptations the SDK/Arcade 11 bump forces.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * Extract mkStringConcat helper for arity-dispatched String.Concat The "concatenate a list of string exprs, picking the cheapest String.Concat overload by arity" pattern was duplicated in CheckExpressions (interpolation lowering) and the optimizer, and our new union ToString used the array overload unconditionally. Extract mkStringConcat into TypedTreeOps.ExprOps and route all three through it. This also lets single-field union cases emit Concat3 instead of allocating a string[] (IlxGen runs after the optimizer, so nothing else would collapse that array form). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * Fix generated union ToString for generic unions The match-based ToString body is a TypedTree expression codegen'd via CodeGenMethodForExpr, but it was built with `eenv`, which lacks the tycon's type parameters. For generic unions this produced wrong IL: the wrong case branch (always the null-as-true-value case) or a NullReferenceException for single-case unions. Use `eenvinner` (the per-tycon environment) so the generic method body resolves its type parameters. The old sprintf path was unaffected because it emits raw IL off the pre-built ilThisTy. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * Render union ToString fields like option (null -> "null") To make a generated union ToString consistent with how option/list format their contents (LanguagePrimitives.anyToStringShowingNull), format each field as: if (box field) is non-null then 'string field' else "null". Previously a null field rendered as "" (the 'string' operator's null behaviour). Generated inline rather than calling anyToStringShowingNull, which is internal to FSharp.Core and so not callable from user-compiled code. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * Tidy reflection-free union ToString tests Normalize union declarations to a leading '|', use System.Console.WriteLine instead of printfn (the printf machinery is what these changes move away from), and make the null-field test compare the union's rendering directly against option's rather than asserting a fixed string. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * Add reflection-free ToString to Result and Choice Result and Choice had no ToString override, so they fell back to the compiler-generated sprintf "%+A" one, which uses reflection. Give them hand-written overrides mirroring option/list (String.Concat + anyToStringShowingNull), e.g. Ok 5 -> "Ok(5)", Choice1Of2 7 -> "Choice1Of2(7)". This is reflection-free / AOT-friendly and consistent with option's "Some(x)" rendering. Note: this changes the observable ToString of Result/Choice from the "%A"-style "Ok 5" to "Ok(5)". Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * Generate a single-line ToString for records under --reflectionfree Records previously fell back to Object.ToString() (the namespace-qualified type name) under --reflectionfree. Generate "{ F1 = v1; F2 = v2 }" on a single line (no line breaks, unlike sprintf "%+A"), with fields formatted like union fields (null -> "null", otherwise via 'string'). Factor the shared field formatter and ToString-method emission out of the union path. The default (sprintf "%+A") path is unchanged. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * Update FSharp.Core surface-area baselines for Result/Choice ToString Result and Choice`2..7 now declare an explicit ToString() override, so they appear in the public surface area. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * Add release notes Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * Generate a single-line ToString for anonymous records under --reflectionfree Drive anonymous-record ToString through the synthetic record tycon (already built for equality/comparison) rather than sprintf "%A", so under --reflectionfree it renders "{| Name = value; ... |}" on a single line. GenRecordToStringMethod now takes open/close brace strings ("{ "/" }" for records, "{| "/" |}" for anonymous records). The default (non-reflection-free) codegen path is unchanged and still falls back to sprintf "%+A". Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * Test that a hand-written ToString override is kept under --reflectionfree Addresses review feedback: generation is gated on `not (HasMember "ToString")`, so a user-defined ToString on a union or record wins over the generated one. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * Rename ToString generators for clarity Addresses review feedback: distinguish the reflective sprintf path from the structural one. GenPrintingMethod -> GenSprintfPrintingMethod (the sprintf "%+A" ToString/get_Message), GenToStringMethodFromExpr -> EmitToStringMethodDef. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * Restore tabular layout for string_operator_info in TcGlobals Addresses review feedback: keep the column-aligned layout of the surrounding intrinsic table. Also makes these two lines byte-identical to the same intrinsic added by #19971, so a future merge resolves cleanly. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * Add reflection-free ToString tests for field shapes, structs, anon records and recursion Covers DU field shapes (multiple fields vs a single tuple field), explicit vs unnamed field names rendering identically, struct unions/records, anonymous and struct anonymous records, and finite recursive/nesting types. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * Add EmittedIL tests for reflection-free record and union ToString Locks in the IL emitted under --reflectionfree: each field is boxed and rendered through Operators.ToString with a null guard, and the parts are joined with String.Concat (array form for the record, 3-arg form for the single-field union case). Nullary union cases return the bare case name. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * Generate reflection-free ToString in the augmentation phase The structural ToString for --reflectionfree records and unions was built in IlxGen, after the optimizer, so its per-field 'string' operator calls were never inlined: each value-type field was boxed and rendered through the generic Operators.ToString, behind a null guard that is dead for a value type. Move the generation into the type-augmentation phase (alongside Equals/GetHashCode/CompareTo) so the body flows through the optimizer. The 'string' operator is now specialised - a value-type field renders via a direct, allocation-free invariant-culture ToString with no boxing and no null guard (reference fields keep the guard so null still renders as "null"). The shared body builders live in AugmentTypeDefinitions; anonymous record types are synthesized too late for augmentation, so they keep generating in IlxGen but reuse the same builder. Output is unchanged; the EmittedIL baselines are updated to the leaner IL. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * Guard generated reflection-free ToString against deep-recursion overflow The augmentation-generated structural ToString recurses into fields, so a deeply nested value can exhaust the stack with an uncatchable StackOverflowException. Emit RuntimeHelpers.EnsureSufficientExecutionStack() at method entry (as C# records do in PrintMembers) so it throws a catchable InsufficientExecutionStackException instead, when the runtime provides the method. The guard is skipped for types whose every field is a flat primitive (integer/float/decimal/string/char/bool/unit/enum), which cannot recurse. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * Test the reflection-free ToString deep-recursion guard A 1,000,000-deep value's generated ToString throws a catchable InsufficientExecutionStackException rather than hard-crashing the process. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * revert ToString additions to fsharp.core types * Remove stale FSharp.Core release note for the reverted Result/Choice ToString Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * Fix code formatting in IlxGen.fs (dotnet fantomas) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * don't use quoted name * int version of reflectionfree-printing doc * doc tweaks * Link release note to the printing doc and cover anonymous records Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * test backticks * Share the ToString recursion guard with anonymous records The guard lived in MakeBindingsForToStringAugmentation, which anonymous records bypass: they are synthesized too late for type augmentation and reach mkRecdToString from IlxGen instead. Deep nesting overflowed the stack rather than raising InsufficientExecutionStackException. Move it into mkToStringRecursionGuard, applied inside mkRecdToString and mkUnionToString, so every caller of the body builders gets it. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * Add EmittedIL baselines for struct and anonymous record ToString Struct records and unions read fields off the this pointer and switch on the tag, and the anonymous record path is generated separately in IlxGen, so each gets its own baseline. The anonymous baseline omits the field reads: they name the anonymous type, whose mangled name is not stable across compilations. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * Fix empty anonymous record ToString rendering a doubled space The open/close braces carry inner spaces ("{| " and " |}"); with no fields they abut and render "{| |}". Trim the leading space when the field list is empty, matching %A's "{| |}".

Supersedes #20200. * Restore NuGetRepack UsingTask workaround for Arcade 10 in Microsoft.FSharp.Compiler.fsproj The merge from main overwrote this project with main's Arcade-11 form, which relies on the Microsoft.DotNet.NuGetRepack.Tasks package auto-importing the UpdatePackageVersionTask UsingTask. On release/10.0.4xx (Arcade 10) that package does not ship the build props, so the task must be declared explicitly. Without it every packaging build leg failed with MSB4036 (task not found). Restores the explicit UsingTask (tracked by #19557) while keeping the CPM-managed PackageReference (no Version attribute).
