Clicking inside the open flags filter popup could act on the
DataGridColumnHeader underneath: unhandled press/release pairs bubbled
out of the popup into the header (which treats them as a sort click
and flashes its pressed visual), and on X11 overlay popups the
light-dismiss machinery could even re-target a click's press directly
at the header while the popup stayed open.
The filter UI is now hosted in a Flyout attached to the funnel icon
instead of a hand-rolled Popup parked in the header's panel. Avalonia
positions Popup as the low-level primitive and recommends Flyout for
attached pickers: light dismiss, Escape-to-close, focus handling, and
theme-correct presenter chrome come built in (the old hard-coded white
background was also wrong in dark mode). The flyout content swallows
unhandled wheel and press/release events, since its internal popup is
still logically parented to the funnel inside the header.
A headless end-to-end regression test drives a real DataGrid with
overlay popup hosts (the X11 OverlayPopups=true configuration the app
runs with) and raw input through the funnel and every visible flyout
control, asserting the header never sorts and never receives an
unhandled press or release.

Opening a package from a feed previously meant downloading the .nupkg by
hand and using File > Open (#2313). The new File menu command searches any
public V3 feed (editable package-source list, persisted as an MRU in the
ILSpy settings), offers the latest 100 versions in a dropdown, and downloads
into the NuGet global packages folder so the cache is shared with every
other NuGet consumer on the machine and nothing is fetched twice. The cached
.nupkg is then opened exactly like the regular Open command. Feed access
sits behind INuGetFeedClient so the headless test suite covers search,
paging, version selection, download, cancellation, and error surfacing
without touching the network.

When enabled, switch sections are ordered by their case label value
instead of by the underlying branch's IL offset. Default is false to
keep existing output unchanged. Useful when diffing decompiler output
across rebuilds of obfuscated assemblies, where IL block layout is
unstable but the case-to-value mapping is not.
Includes an ILPretty test that exercises a hand-written switch whose
table targets are placed at non-monotonic IL offsets (simulating
obfuscator block shuffling) and verifies the cases come out in
label-value order with the setting enabled. Also adds the
Resources.resx / Resources.Designer.cs entry so the WPF settings UI
shows a proper label instead of the raw key.

* Fix anonymous-type lambda early-return emitting unresolvable cast
When a lambda's inferred return type contains an anonymous type and one
branch returns null, the decompiler emitted an explicit cast such as
`return (IEnumerable<<>f__AnonymousType0<int>>)null;`, which is invalid C#.
Skip the cast in IsPossibleLossOfTypeInformation for null literals whenever
the expected type contains an anonymous type:
null is implicitly convertible to any reference type, so no cast is needed,
and the anonymous type has no nameable form to cast to anyway.
Fixes#3751
ECMA-335 names the zero state of most mutually exclusive sub-ranges
(NotPublic, AutoLayout, Class, AnsiClass, PrivateScope, ReuseSlot, ...)
and the reflection enums declare those members, but the schema inferer
skipped zero-valued fields and synthesised a generic '(none)' entry
instead. Zero fits every mask, so the member is attributed to a group
by declaration order: ECMA-335 and the reflection enums declare each
mask directly followed by its members. Filter persistence stores
numeric values, so saved filters are unaffected by the label change.

The schema inferer only walks the enum's declared fields, so the
ECMA-335 Forwarder bit (0x00200000, no member in
System.Reflection.TypeAttributes) was invisible to the per-column
flags filter even though the cell tooltip already shows it. An
explicit per-enum extras table appends it as an independent flag,
making forwarders filterable on the ExportedType table.

The blob was tracked 100644, so every fresh checkout (and any branch
switch in a worktree hosting the shared .git/hooks symlink target)
produces a non-executable hook script, which git then silently skips
with only an 'ignoredHook' hint. With core.fileMode=false on this
clone a plain chmod is git-invisible; the mode has to be fixed in the

0x00200000 is the ECMA-335 Forwarder bit (II.23.1.15), set on

Two Options tests selected the whole System.Linq.Enumerable type and then
awaited WaitForDecompiledTextAsync. That decompile takes >15 s in headless and
overran the 60 s wait on a loaded CI runner, so the suite flaked intermittently
(green in one run of a commit, red in another). The behaviours under test --
that a re-decompile setting refreshes the active tab, and that the refresh does
not steal focus from the Options tab -- fire on whatever the tab shows, so a
single small method exercises them just as well and decompiles near-instantly.

Selecting a C# version, switching to a version-less language (IL), then back to
C# left the toolbar's version ComboBox blank even though LanguageService had
restored CurrentVersion. The MVVM-toolkit setter runs OnCurrentLanguageChanged
(which assigns CurrentVersion, pushing it onto the bound SelectedItem) before it
raises PropertyChanged for CurrentLanguage (which repopulates ItemsSource from
the new language's versions). So SelectedItem is set against the previous
language's still-stale, empty list, rejected, and never re-pulled once
ItemsSource updates.
Re-assert the version combo's SelectedItem from the bound CurrentVersion after
each ItemsSource swap settles, keeping the model untouched.

CaretHighlightAdornerTests waited on the wall clock (3s budget) for the
adorner's 1s real-time DispatcherTimer to remove it. Avalonia.Headless has no
simulated clock, so under a loaded CI runner the dispatcher-thread timer plus
the poll loop slipped past the tight budget and the test timed out
intermittently.
Extract the teardown the lifetime timer runs into Dismiss(); the test grabs the
live adorner and calls it directly, verifying the unregister half without any
timing dependency. Registration is still exercised through the real
OnReferenceClicked path, and production behaviour is unchanged.

These three project settings were present in the WPF build but lost in the
move to Avalonia. RollForward=major matters most: the default publish is
framework-dependent (publish.ps1 uses --no-self-contained) and the app targets
net10.0, so without it a machine that only has a newer major runtime installed
fails to start the app. DynamicAdaptationMode (DATAS) lets server GC shrink its
heap count to the live load for a smaller idle working set, and Debug-only
CheckForOverflowUnderflow traps arithmetic wrap during development.

Generate-PDB and assembly-node decompile failures reported only the exception
Message, which is too thin to act on: the runtime-async PDB-generation crash
surfaces as a bare "Object reference not set to an instance of an object" with
no indication of where it came from. Append the whole exception (type, message,
stack trace, inner exceptions) inside a default-collapsed "Exception details"
fold so the report stays scannable while the trace is one click away.
The fold span is counted in WriteLine() calls rather than embedded newline
characters, so the trace is emitted one line per WriteLine() -- a single
Write() of the multi-line string would collapse to one counted line and be
dropped as a single-line fold.
Also fixes the PDB tab title showing a literal "{0}": the GeneratingPortablePDB
resource is a format string whose placeholder was never filled.

Debug.Assert failures were routed straight to the single-button unhandled-
exception dialog and deduplicated by call site, so the only available action
was effectively "ignore". Restore the developer dialog the WPF host offered:
Throw raises the assertion as an exception, Debug breaks into the debugger,
Ignore continues, and Ignore All suppresses that call site for the session.
Asserts fire on the background decompiler thread, so the dialog marshals to the
UI thread and blocks the caller on a nested dispatcher frame until a choice is
made, matching how the WPF version stayed responsive.
Separately, cancelling a long-running operation tab left it blank; it now shows
"Operation was cancelled." so the frozen tab explains why it stopped.

Toggling a display setting that affects decompiler output (folding, member or
using expansion, debug info, IL detail, indentation) routed through
ForceRefreshActiveTab, whose ShowSelectedNode re-projects the tree selection
and so activates the preview tab -- yanking the user off whatever tab they were
on (e.g. the live Options page they were editing).
Add RefreshDecompilerOutputInPlace, which re-decompiles the cached decompiler
content directly without re-projecting or activating anything, and route the
Redecompile display-setting reaction to it. F5 reload and dependency-load keep
using ForceRefreshActiveTab, where re-projecting the selection is intended.

Project/solution export (and other RunInNewTabAsync work) opened a tab with a
static title and a permanently indeterminate progress bar, even though the
whole-project decompiler already produces per-file DecompilationProgress that
was being dropped.
Wire that progress through: DecompilationOptions carries an
IProgress<DecompilationProgress> that DecompileAsProject sets on the
WholeProjectDecompiler; a new RunInNewTabAsync overload hands the work a
UI-thread-marshaled Progress<T> feeding the tab. The tab now animates the
braille spinner over its title (the operation name) and shows a determinate bar
plus the file currently being written and an "N of M" count. Solution export
reports per-assembly rather than per-file, since its assemblies decompile in
parallel and per-file reports would race. The determinate bar is pinned to 75%
of the overlay width so it doesn't jitter as the status text changes.

The README still described ILSpy as a WPF app. Reflect the current reality:
the desktop UI is cross-platform Avalonia (Windows/Linux/macOS), the solution
filters are ILSpy.Desktop.slnf / ILSpy.XPlat.slnf (no ILSpy.Wpf.slnf), Unix/Mac
can build and run the UI, and the build requires the .NET 11 SDK. In CLAUDE.md,
the net472 add-ins / installer / Windows-bound tests are Windows-only frontends
and extra tests, not a legacy porting backlog.

Make the repo-root pwsh scripts the mandated path for restore/build/update-deps/
format/clean/publish, and explain why: the bare dotnet commands prune the
packages.lock.json files (the recurring spurious lock-file diff). Add two code

wrote them, and edits made outside the session must not be reverted without
confirmation. Drop the "Framework-specific gotchas" section, which only covered
a few narrow UI control quirks.

The Debug Steps pane previously only served the ILAst language (one node per
IL transform). The C# decompiler's intermediate AST states were instead
exposed as a row of extra "C# - after TRANSFORM" dropdown languages, which
cluttered the language list and only let you jump to one fixed step at a time.
Generalise the pane to an IDebugStepProvider interface: ILAst keeps its IL
steps, and the C# language now contributes one step per AST transform, mapping
a selected step onto options.StepLimit (already honoured by CreateDecompiler).
Each language also supplies its own options object, so the writing-options
checkboxes show for ILAst and nothing for C#. The per-transform dropdown
languages are removed in favour of this.

ICSharpCode.Decompiler / ILSpyX / BamlDecompiler set RestoreLockedMode but
declared no RuntimeIdentifiers, so their lock files were RID-agnostic. A
RID-specific 'dotnet publish -r <rid>' of ILSpy (which declares all four
distribution RIDs) propagated the RID to these locked project references and
failed restore with NU1004 unless --no-restore or --force-evaluate was used.
Declare the same win-x64;win-arm64;linux-x64;osx-arm64 set on the three
libraries and regenerate the locks so a locked-mode publish works for every
platform out of the box.

The 23 typed table-row viewmodels each inlined the same
MetadataOffset + GetTableMetadataOffset + GetTableRowSize * (rid - 1)
arithmetic, and the four heap tree nodes each repeated an identical
lazy-cache / "{name} Heap (count)" header / CreateTab shell that differed
only in the heap name and how rows are walked. A single mistyped
TableIndex or a divergent cache shell would have been invisible across
that many copies.
Add MetadataTableTreeNode.GetRowOffset (with a MetadataReader+offset
overload for the one entry that lacks a MetadataFile) and a generic
MetadataHeapTreeNode<TEntry> base carrying the cache, header, and tab,
leaving subclasses to supply only the name and row materialiser.

DockWorkspace carried the reflection-heavy metadata-grid resolution: read a
clicked token cell, resolve a double-clicked row to its tree node, and find
the metadata-table node a token points at -- with the "read the row's
metadataFile private field + int token" reflection block copy-pasted between
the cell-click and row-activation paths. As the WPF host kept this metadata
logic out of the main workspace, lift it into a MetadataNavigator service.
DockWorkspace keeps the dock-side actions (select, scroll-to-row, history
stamping, open-in-new-tab) and now delegates resolution; the public
NavigateToToken / TryResolveRowToTreeNode surface is unchanged, so the
external callers (ShowInMetadata, DecompileMetadataRowInNewTab) don't move.
The duplicated reflection collapses into one TryReadRow.

AssemblyTreeModel carried a ~180-line node-finding subsystem -- resolve a
reference (entity / namespace / resource / assembly / metadata file) or a
saved path to its tree node -- that has nothing to do with the class's
selection and list-lifecycle responsibilities. Lift the implementation into
a TreeNodeLocator, with the locator taking the tree root and assembly list
as parameters so it stays stateless.
The model keeps its public FindTreeNode / FindNodeByPath / GetPathForNode as
thin delegators (they're called from DockWorkspace, SearchPaneModel,
AssemblyTreeNode and tests), so no external call site changes -- the god
class just sheds the implementation.

ApplyDocument was a 116-line god-method and the constructor a 112-line wall
of unrelated wiring. Both are linear sequences with no shared control flow,
so split them into intention-named steps:
ApplyDocument (now ~40 lines) orchestrates RebuildFoldings,
RestoreOrResetViewState and SwapCustomElementGenerators; the constructor
(now ~30 lines) calls SetupElementGenerators / SetupBackgroundRenderers /
SetupHoverHandlers / SetupContextMenuAndHyperlinks / SetupRichPopup /
SetupZoomAndCopy. Order is preserved exactly. Pure refactor, no behaviour
change.
The five renderer/generator/popup fields lose `readonly` since they are now
assigned in the ctor-only Setup helpers rather than the ctor body; they are
still single-assignment in practice.

The Options page is non-modal and live-apply, so -- unlike the WPF host,
which ran a full assembly-list Refresh() when its modal Options dialog
closed -- a setting that changes the decompiler/disassembler output (brace
folding, member/using expansion, debug info, IL detail, indentation) had
nothing to make it take effect; toggling it did nothing until the user
re-navigated.
Classify every DisplaySettings property in one table (DisplaySettingReactions:
editor-live / tree-text / tree-shape / re-decompile / none), grounded in the
actual consumers (ApplyDisplaySettings, GetIndentationString, the IL/mixed
languages). OnSettingsChanged dispatches on it, and a coverage test asserts
the table spans every settable property so a newly-added one can't silently
fall through.
Fixing the re-decompile case exposed that ForceRefreshActiveTab was itself a
no-op for an unchanged node -- ShowSelectedNode re-sets CurrentNodes, whose
setter dedups -- so RefreshDecompiledView (also used after dependency
resolution) never actually re-ran. Add DecompilerTabPageModel.Redecompile()
to force past the dedup and call it from ForceRefreshActiveTab.
Also drop the EnableSmoothScrolling setting: it drove TomsToolbox's
AdvancedScrollWheelBehavior in WPF, which the Avalonia port doesn't use and
never replaced, so the checkbox persisted a value nothing read.

The UseNestedNamespaceNodes and HideEmptyMetadataTables handlers both
force a materialised node to re-create its children (clear, re-arm
LazyLoading, EnsureLazyChildren), guarded on it not already being lazy.
That's a general tree-node operation -- a soft, in-place rebuild that
re-runs LoadChildren without reloading the assembly -- so it belongs on
SharpTreeNode next to the lazy contract it builds on, not as a private
helper in the model. Both call sites now use node.ReloadChildren().

The drag-drop / file-drop callback selected the dropped assemblies with a
raw SelectedItems.Clear() + Add() loop, which flashes a transient empty

the swap so the selection-changed fan-out fires once, with the final set,
never empty. A transient empty poisons the grid-sync deferred guard, after
which the tree stops following tab activation. Route the callback through
SelectNodes; a regression test asserts no empty SelectedItem is observed
mid-drop.

DecompileAsync and ShowText both pushed the same eight properties (syntax
