'this' and 'base' both read the 'this' parameter of the function being
decompiled, but their resolve result did not say so: consumers that key on
ILVariableResolveResult (local-reference output, highlighting, hover) could
not connect the keyword to the variable, and the qualified/unqualified
spellings of the same access carried differently shaped annotations.
The resolver has no ILFunction and thus no variable to put into a
ThisResolveResult, so it stops synthesizing one: LookInCurrentType looks
the name up against the (self-parameterized) current type, which grants
the same protected access, and the annotation of an unqualified field
access is built from the translated target instead. ResolveThisReference
and ResolveBaseReference had no callers left and are removed.

A call to a value-type constructor is rewritten into
"stobj(target, newobj ...)" because "Struct.ctor(target, ...)" has no C#
equivalent. The rewrite keyed on TypeKind.Struct, so a struct from a
missing assembly resolved as TypeKind.Unknown, fell through to the
ordinary call path and produced a stack-type mismatch.
Metadata cannot settle the question: a TypeRef parent carries no valuetype
bit. The receiver can, though - a constructor invoked with "call" on an
address is a shape only a value type has - so the unresolved case follows
the receiver's stack type and steps aside where metadata does say the type
is a reference type. Reading the receiver has to leave it on the stack for
PrepareArguments, hence the depth-indexed peek.

Structs whose assembly is missing decompile through the unresolved-type

Review follow-ups on #3998: reject non-finite parses (NaN slips through
Math.Clamp and, once persisted, permanently fails the editor's
SelectedFontSize > 0 guard), commit the clamped value back into the box on
focus loss (the echo suppression otherwise leaves a typed "3" on screen while
6 pt is stored), and assert the theme actually realizes PART_EditableTextBox
instead of trusting the IsEditable property. The 4/3 pt/px ratio is documented
as the WPF-host convention it is - exact on Windows/X11, deliberately not the
Cocoa-point number on macOS - rather than a universal.

The options dialog bound DisplaySettings.SelectedFontSize (device-independent
pixels) straight into a NumericUpDown, so a fresh profile showed 13.33 and the
6-72 bounds were pixels. The WPF host presented points via FontSizeConverter;
this restores that behavior on Avalonia with an editable size ComboBox (like
the Windows font dialogs) backed by a pt/px proxy on the viewmodel. The stored
value stays pixels so settings files keep round-tripping with ILSpy 9.x.

Comments used to be child nodes flushed by InsertSpecialsDecorator when the
next node started printing, which put the marker of an init-only setter right
after the keyword. In the slot AST comments are leading/trailing trivia, so the
accessor's trailing trivia moved the marker behind the accessor body. The
placement cannot go back to trivia on the body either: the auto-property
transform drops the body, and the marker with it. The accessor now carries the
init-only fact itself and the printer writes the marker next to the keyword.

Overload resolution reports no error for an empty candidate set - there is
no best candidate to attach one to - so the null result passed for success
and was dereferenced while checking the call target. Decompiling
FSharp.DataFrame from nuget.org crashes that way: F# compiles its comparison
members to instance methods carrying operator metadata names, and the
operator candidate search looks at the operand types rather than at the
receiver type the member belongs to.
The new fixture pins that such an assembly decompiles at all. It still
renders those instance methods as operators and drops the receiver at the
call sites, which is the misclassification behind the empty candidate set
and is handled separately; this is the guard that keeps an empty candidate
set from being read as a resolved call.

Two paths generate a local named "field" inside an accessor - a local
typed after a class named Field, and one named after the GetField method
it is assigned from - and C# 14 rejects that identifier there (CS9273).
Worse than the compile error, the local shadows the keyword, so a
backing-field read silently becomes a read of the local; both paths now
have a fixture, verified to regress without the name reservation.
A static member named "field" cannot be disambiguated with "this.", so
the accessor has to name its declaring type; that path had no coverage
either.

VB emits an auto-property as a "_<PropertyName>" backing field plus accessors
it does not mark [CompilerGenerated]. The pre-C# 14 transform knows this: it
relaxes its accessor requirement whenever it finds such a field, which is how
a VB auto-property still prints as "{ get; set; }".
Routing every property through the field-backed path lost that. Collapsing an
accessor demanded [CompilerGenerated] unconditionally, so a VB auto-property
stopped collapsing and grew explicit "field" accessors instead - correct code,
but noise where every other compiler's equivalent stays a one-liner. Only the
legacy vbc configurations show it, and those run on Windows alone, so the
Linux and macOS jobs stayed green while both Windows ones failed on
VBPropertiesTest and Async.

Backing-field references inside a property's own get/set/init accessors
are emitted as the `field` keyword at IL-to-AST translation time
(ExpressionBuilder.ConvertField), so arbitrary accessor bodies become
expressible and no separate rewrite pass is needed. Compiler-generated
trivial accessors then collapse individually to `get;`/`set;`, which
also handles mixed shapes like `{ get; set { ... field ... } }`; the
backing-field declaration is removed with its remaining attributes
re-hosted as `field:` sections, and constructor stores become property
initializers (or property assignments, for setter-less properties).
Implicit zero-stores that auto-default struct constructors emit for
unassigned backing fields are dropped rather than lifted.
Recognition stays AST/metadata-based rather than mirroring the ILAst
analysis used for automatic events: events must prove compiler-generated
bodies before discarding them, while the field keyword discards nothing,
so name association plus the accessor context is sufficient.
Below C# 14 (or with the new FieldKeyword setting off), the field
declaration survives under its metadata name, so the UI keeps showing
the truth; EscapeInvalidIdentifiers - the transform the compilable-output
flows (project export, VS, tests) already add - now maps
`<P>k__BackingField` to the readable `P__BackingField` instead of the
generic character escape. A genuine field literally named "field" is
qualified as `this.field` inside accessors, and locals are not named
"field" there, since C# 14 rebinds the bare identifier. Bodiless
accessors mixed into multi-line properties get their own line in the
output.
The fixture covering the feature surface lands with the implementation rather
than as a separate xfailed commit. It is excluded from the test-assembly
compilation because its nullable annotations would trip warnings-as-errors
there.

In generic types, resolve results reference members specialized by the
type's own type parameters. The worklist dedupe and entityMap in
DoDecompile(ITypeDefinition) are keyed by definition, so a hidden member
re-added through the worklist (e.g. a property backing field referenced
from an accessor) was decompiled under a key the output pass never looks
up, silently dropping the declaration while keeping its uses.

The parameter-list-less anonymous method form is compatible with any
delegate signature, and C# code must rely on exactly that when a
delegate's parameter types cannot be named at the use site: IL, unlike
C#, permits a delegate signature to reference less accessible types.
Expanding such an anonymous method into a lambda would force the
unnameable type into a parameter list. Keep the delegate form, with its
parameter list dropped, when the parameters are unused and one of their
types is not accessible from the current context.

Under UseLambdaSyntax, anonymous functions became lambdas only when an
expression body was possible; statement-bodied ones kept C# 2 delegate
syntax. Now every anonymous function whose parameter shape a lambda can
express uses lambda syntax; delegate syntax remains for ref/out/in and
params parameters and for pre-C# 3 language profiles.
Two latent issues surfaced by the wider lambda coverage: DeclareVariables
assumed an insertion point directly under a LambdaExpression is an
expression body it must convert to a block, which block-bodied lambdas
now violate; and anonymous methods declared without a parameter list
carry compiler-generated parameter names like '<p0>' that are not valid
identifiers, so the lambda's mandatory parameter list regenerates such
names from the parameter type: (object obj, EventArgs e) => ...
A side effect visible in fixtures: an explicit parameter list can make
a delegate-creation cast redundant that bare 'delegate' syntax needed
for overload resolution, e.g. new Thread((ThreadStart)delegate { })
becomes new Thread(() => { }).

Element 8+ of a long tuple is read through the Rest field, which Roslyn
loads by value; ILSpy turned that into an addressof over the loaded
copy, hiding the tuple field chain from every downstream matcher. Elide
the copy when the enclosing expression only reads through it - the read
then goes directly through the original address and folds into the
usual Item_N chain. The deconstruction transform's use-shape guard also
learns to walk that chain; whether each read really is a consumable
element access remains the job of MatchTupleElementRead and the escape
check.

Deconstruction assignment copies the right-hand side into a temporary
before calling Deconstruct. When the RHS is a call, inlining folds that
temporary away, but for a local or parameter it survived into the
output as a separate assignment statement. Consume the copy into the
deconstruction pattern; rendering the copied value as the RHS
recompiles to the identical temporary. Because blocks are processed
back to front, the call-position match defers to the attempt starting
at the copy, mirroring the existing nested-deconstruction defer guard.
The new fixture also covers deconstruction assignment to locals
captured by a lambda in an async method (issue #3037's crash shape,

Review of #3989 pointed out that guarding registration on the theme-aware
marker conflates "XSHD opts out", "already themed" and "already registered",
and leans on two non-contractual AvaloniaEdit details (the delay-load
wrapper's Properties forwarding and its materialize-on-touch behaviour).
Keying the pristine-colour snapshots by colour instance (ConditionalWeakTable)
instead of by definition makes the in-place theming idempotent no matter how
many definition identities expose the colours, so correctness no longer
depends on registration order or the marker; the guard remains only to honour
the XSHD opt-out and to skip redundant list entries. ApplyHighlightingColors
is now private so nothing can set the marker outside a registration.
Also from review: the new tests move to a uniquely named fixture (the old
name collided with Themes/ThemeAwareHighlightingColorizerTests), gain
coverage of the Light/Dark switch path after a dark startup, and the cache
characterization asserts the reconverted content instead of relying on inert
theme switches.
Assisted-by: Claude:claude-fable-5:Claude Code
With dark preselected, the first document of a session rendered with a
double-converted (washed-out) palette; resources showed it across every
token, C# only on tokens outside the hand-authored dark palette. The
same definition was registered with the theme manager under two
identities: HighlightingManager hands out a delay-loaded wrapper whose
members forward to the inner definition that HighlightingService.Load
registers during materialization. Registering the wrapper afterwards
snapshotted the shared colours AFTER the inner registration had already
darkened them, so the snapshot's "light originals" were dark values and
the rewrite darkened them a second time. In-session theme switches were
unaffected because the first touch happens in Light, where both
snapshots are pristine -- which is why the bug only appeared when dark
was already active at first touch.
Skip registration when the definition is already theme-aware: reading
the marker forces the wrapper to materialize, so the check observes the
inner registration. This also stops the remap from clobbering
definitions whose XSHD opts out via ILSpy.IsThemeAware.
Assisted-by: Claude:claude-fable-5:Claude Code
ThemeManager and ThemeAwareHighlightingColorizer split dark mode between
them: the manager darkens a registered definition's named colours in
place, the colorizer per-paint-remaps colours of unregistered
definitions. Running both on one definition converts every colour twice
and washes the palette out. The colorizer captured IsThemeAware once in
its constructor, so a definition registered after the colorizer was
created would be double-converted from then on. Today every colorizer
is created after registration (HighlightingService registers inside
GetByExtension/Load before returning), but that is a calling
convention, not an invariant; reading the flag per paint removes the
ordering dependency.
The colorizer's dark-conversion cache needs no matching flush: its keys
use HighlightingColor's content-based equality, so recolouring a source
colour in place changes its hash and the lookup misses instead of
serving a conversion of the old values. A characterization test pins
that, so an equality-semantics change in AvaloniaEdit shows up as a red
test rather than as stale colours.

These explain the code by pointing at the front-end that used to implement it.
That front-end is no longer in the tree, so the referent a reader would go
looking for does not exist: "Mirrors WPF's RefreshDecompiledView() call" names
a method nobody can open. In almost every case the sentence beside it already
carried the reason, and the reference was an appendix.
Comments citing a live platform difference are left alone, because there the
comparison is the reason rather than a memory: Avalonia genuinely has no
global RequerySuggested signal, which is why SimpleCommand exists at all.
One had gone stale rather than merely redundant. DerivedTypesEntryNode
described consulting the active search term as a missing feature to reinstate,
but SearchTermMatches is deliberately a no-op so the assembly tree stays
independent of the search pane; the comment now says so.

A comment that justifies behaviour by pointing at the WPF front-end means
nothing to someone reading the file cold: the reason is either already stated

why the tree filter ignores the search term.

Zoom was stored as the font size itself, so the zoom overlay had no way to
tell a Ctrl+Wheel zoom from a font size picked in the options dialog: any
size other than the hard-coded default made the overlay appear, and the
percentage was measured against that default rather than the user's font.
A separate multiplier restores the split the setting always implied - the
options dialog moves the base size, zoom scales it - so 100% means "the
font you configured", whatever that is.

The guard added here reads the target of a member access to decide whether an
assignment may move into a field initializer, and it recognises the current
instance as a ThisResolveResult. Only one of the two spellings produces that.
An unqualified `A` is resolved through CSharpResolver.LookInCurrentType, which
synthesizes the target as a this-reference; an explicit `this.A` is built by
ExpressionBuilder, whose TranslateTarget hands back whatever ConvertVariable
produced - and `this` is a parameter like any other there, so the target is an
ILVariableResolveResult. The guard saw the first and missed the second.
Which spelling appears is decided by RequiresQualifier, for reasons unrelated
to the question being asked: a constructor parameter that shadows the field
forces the qualifier, and AlwaysQualifyMemberReferences forces it everywhere.
So the transform hoisted `b = this.value + 1` into a field initializer, where
naming the instance is CS0027 and the output does not compile.
TranslateTarget already builds a ThisResolveResult for `base`, one branch
above. Doing the same for `this` leaves the guard untouched and makes it see
both spellings, and spares every future consumer the same trap. The type is
carried over from the previous resolve result, so nothing downstream observes
a different one - the this/base keyword links read exactly this node.
Fixes#3984.

Five fixtures covered the "Use nested namespace structure" setting, four of
them running the same toggle at a different layer: the model shape, the same
toggle awaited live, and the same toggle again asserting it reached the
SharpTreeView's rows. Each paid its own boot for a scenario that is one story
end to end, and together they were the second-largest block of time in the
suite after the process-list scroll loops. One test now walks the whole path
once, carrying every assertion the four had, including the nesting depth only
the first checked.
The comparison view's model-is-bound test is dropped: the test after it
renders rows out of that model, which cannot happen unless it is bound, and
it opened two fixture assemblies to prove it.
The expander hitbox test asserted the toggle measures 13x16 and its glyph 9x9,
then clicked 14px down to prove the area below the glyph is live. The click
proves the geometry; the measurements only restate it, and would fail on a
font-metric change that broke nothing. Its layout-settling loop slept 200ms
unconditionally, which is a race that usually wins - it now waits for the
condition it needs.

These fixtures were written while porting to Avalonia, as an author's own
verification step rather than as coverage: reflection asserting that a type
derives from its base and that a property has the type it is declared with;
literals (MinHeight 29, Padding 3, MaxWidth 900) copied out of the .axaml
beside them; a property override asserted only so pane descendants stay
reachable from tests. None of them can fail except when someone deliberately
edits the line they mirror, and then they fail as a chore.
StartupPerfTests keeps its two [Explicit] benchmarks, which print per-phase
timings worth reading. The third was a wall-clock assertion (8 CoreLib copies
must settle in under 15s) that ran in CI, where a shared runner decides the
verdict; as [Explicit] it would be strictly dominated by the 200-assembly
benchmark it was derived from, so it goes.
Two fixtures are trimmed rather than deleted, because their kernel is real:
XmlDocLoader's ref-pack fallback has no other test in the repo, and the
MenuIcon metadata rasterisation was dropped once during the port already.
Both now assert that without booting MainWindow to reach it.
This is worth about two seconds - it buys reviewers less to read, not CI
less to do.

Tuple element names and nullability are not part of a type's identity, so an
interface resolved through one of its members carries neither. Naming an
explicit implementation from that type produced `void I<(int, int)>.M()` on a
type declared as `I<(int A, int B)>`, which the C# compiler rejects outright
with CS0540 - the decompiled source did not build. The nullable case was
already recorded as a TODO in the NullableRefTypes fixture, where the mismatch
costs a CS8643 warning rather than an error.
The implementing type's base-type list is the only place those annotations are
recorded, so the qualifier is looked up there. Three call sites derived it
independently - the AST builder for all five member kinds, the ambience used
for tooltips and tree labels, and the forwarders synthesized for MethodImpls -
so they now share one helper rather than repeating the rule twice more.
Matching while ignoring tuple names and nullability cannot be ambiguous:
implementing two interfaces that differ only in those is itself an error
(CS8140, CS8645).

An export's ITextOutput goes nowhere: ProjectExporter and SolutionWriter both
hand the language a throwaway PlainTextOutput and build their own status
report, so a language writing failures into that output is invisible. The
failures travel on DecompilationOptions instead and are rendered by the caller
that owns the report - each one with its full exception in a collapsed fold,
which is what makes a bug report actionable.
Drive-by: WriteExceptionDetails split the exception text without trimming, so
for exceptions rendering a trailing newline the fold reached one line past the
last frame and swallowed the line behind it; and the tab's own decompilation-
failure path had regressed to dumping a raw stack trace instead of using that
helper.

One member the decompiler could not handle aborted the whole export, so a
single unsupported method in a large assembly left the user with nothing: no
sources, no .csproj, no way around it. Recovering silently would trade that
for a worse outcome - broken output nobody knows is broken - so every failure
is recorded, written where the content would have gone, and pointed at the
issue tracker.
The recovery has to hold for anything the export touches, not just method
bodies: a file that cannot be created, a resource that cannot be decoded, an
output visitor that throws mid-type. Each of those costs its own unit and
nothing else, and the units behind a failure are still produced - dropping
them would make the export look complete when it is not.
Consumers that relied on the exception keep their failure signal: ilspycmd
exits non-zero and lists the failures, the PowerShell cmdlets raise an error
record per failure, and the round-trip suite asserts the export reported none
- otherwise a crash on a method its own tests never call would ship green.

A query source can be reached through an indexer as well as through a member
access or a call: `holder?[0].Where(...).Select(...)` puts an IndexerExpression
between the LINQ call and the `?.`. The receiver walk stopped there, so query
syntax was still introduced over a source the conditional access had lifted to
a nullable value type, and the output failed to compile with CS1936 - the same

The language version appears in two places that share a name but not a
concept, which repeatedly reads as one confused API: on
DecompilerSettings it is a construction shortcut (SetLanguageVersion
initializes the feature flags once and the version is not stored, so
the flags are the only state and the call is deliberately one-way),
while on WholeProjectDecompiler it is an export parameter (the
LangVersion stamped into the project file, defaulting to
GetMinimumRequiredVersion() and rejected below it as a safety net
against exporting uncompilable projects). Spell both roles out in the
XML docs so the distinction no longer has to be reverse-engineered.

The LanguageVersion setter's InvalidOperationException is a safety net
against exporting a project whose LangVersion cannot compile the

that gap while keeping the setter's immediate feedback.

The setting carried the C# 11.0 display category but was missing from
both SetLanguageVersion and GetMinimumRequiredVersion, so decompiling
for an older target language version could still produce switches over

it like the other C# 11.0 settings closes that gap; the category string
is now derived from the version like everywhere else.
