Avalonia apps pack every resource (compiled XAML, image/SVG assets, ...)
behind a single !AvaloniaResources manifest blob, which until now fell
through to the generic resource node and could not be browsed. Parse the
blob's index and expose each packed file as its own entry, mirroring how
.resources files are unpacked, so individual files can be viewed and
saved. The reader is bounds-checked against crafted offsets/sizes in the
same defensive spirit as the recent .rsrc parsing guards.

The replay tests only checked DebugStepHighlight was non-null, which the
ancestor fallback satisfies unconditionally -- a regression widening every
highlight to the enclosing method would have passed. Assert instead that the
range lies in bounds, does not span the whole document, and (unless it is a
zero-length removal caret) covers non-whitespace rendered code.

NodeLookup.AddNode indexed every annotation of every rendered node by reference
identity, but the debug-step highlighter only ever looks up the DebugStepMarker;
the rest were dead keys, and a shared annotation (ResolveResult and friends,
copied across nodes) would resolve to whichever node rendered last. Make
DebugStepMarker public and bridge only it -- behaviour-preserving for resolution
while dropping the per-annotation dictionary churn on every rendered node.

The step tree can run to hundreds of entries per decompile, so finding a
specific mutation means scrolling. Add a filter box in the pane's top-right
corner: a row survives when its description -- or any descendant's -- contains
the text (case-insensitive), keeping the path to every match, and the tree
auto-expands while filtering so matches nested under transform groups stay
visible. Implemented as an item-visibility converter over the existing TreeView
rather than switching to SharpTreeView, which would change the Steps contract
and rewrite the pane's tests for no functional gain here.

A step that removes a node has nothing left to highlight in the resulting text,
so range resolution fell back to the enclosing block and flooded it. Record the
changed node's surviving neighbours as seam anchors (captured before the
mutation) and split a step's candidates into precise / seam / ancestor tiers:
when neither the node nor its marker resolves, place a zero-length caret at the
gap -- the successor's start, else the predecessor's end -- and only fall back
to the enclosing block when no neighbour survives. A zero-length highlight is
rendered as a caret (positioned, pulsed, centered) with no background mark.

MarkNodeStart and BeginSpan captured builder.Length to anchor a node range
or highlight span, but indentation is written lazily on the first token of a
line. A node or span opened at the start of an indented line therefore
recorded its start before the leading tabs, so the debug-step highlight (and
any span) extended back across the indentation to column 0.
Flush the pending indent in both before capturing the offset, matching the
WPF AvalonEditTextOutput.BeginSpan the Avalonia port derived from. The emitted
text is unchanged -- the indent is written either way, in the same place; only
the recorded start moves to the first real character.

The Debug Steps "show state before/after" replay re-decompiles the active
tab; the headless UI tests inferred completion by polling IsDecompiling +
Text, which can return on stale state or hit the 60s wait deadline when
that shared signal races under CI load (the observed intermittent CI
timeout). RestartDecompileWithStepLimit now returns the decompile Task so
the replay completion can be awaited deterministically; the tests await it
instead of polling. The production IsDecompiling reset is unchanged -- the
last decompile's finally always resets it; the race was only in the test's
completion inference.

The C# debug-steps view highlights and centers the exact AST node a
transform changed; the ILAst view already had the step tree and
replay-at-step but produced no highlight. Bring it to parity.
IL rendering has no token-writer seam like the C# output visitor, so
per-instruction text spans are recorded by bracketing
ILInstruction.WriteTo via a new INodeTrackingOutput. The dominant
inst.ReplaceWith(newInst) transform pattern detaches the instruction
passed to Step, so ILTransformContext gains EndStep to record the
produced instruction; Stepper additionally records the position's
ancestor chain as fallback candidates before the step-limit throw, so
the "show state before" view -- which halts at the selected step --
still resolves to a surviving ancestor (ultimately the ILFunction).
The highlight-range resolver is shared with the C# language.

ILSpy resolves an assembly's references against the target framework it
detects from the TargetFrameworkAttribute. When that attribute is missing,
wrong, or the user wants to force a different framework, there was no way to
hint the correct one, so references could resolve against the wrong runtime
pack or framework directory.
A LoadedAssembly can now carry a TargetFrameworkIdOverride that short-circuits
detection (it is the single value every LoadedAssembly-based resolution path
reads), is persisted in the assembly-list XML, and is carried across a reload
so a runtime change re-resolves against the new framework. The "Set Target
Framework" context-menu entry edits it through a dialog with a free-form text
box and an always-visible list of common monikers to pick from (the app forces
overlay popups, so a dropdown would be clamped inside the small dialog); input
is validated and converted from the short TFM users know (net48) to the long
FrameworkName form the resolver consumes (.NETFramework,Version=v4.8) via
NuGet. The direct DetectTargetFrameworkId callers in the decompiler core
(project export, language version) intentionally keep reading the real
attribute; only reference resolution is overridden.
Resurrects a 2020 prototype (branch tfmoverride) re-implemented against the
current ILSpyX/Avalonia code, whose surrounding structures no longer matched.

- Extract MatchesBookmark for the token + assembly identity that tied a bookmark
to a member; GetLineForBookmark and DocumentContainsBookmarkToken each spelled
it out (four copies), so a change to the match rule had to be made everywhere.
- Add a FoldingSection overload to FoldingsViewState.Restore and route the
bookmark folding restore through it, dropping a duplicated checksum + match loop.

the line never reads as disabled while an active bookmark sits on it.

Two costs on the gutter's hot path:
The margin rebuilt its document-line -> glyph map on every Render, resolving
each bookmark by scanning the document's reference segments. A scroll, a hover,
or the 600 ms post-navigation pulse repaints many times a second, so this
rescanned the references per bookmark per frame. Compute the map once and reuse
it, clearing the cache only when the document or the bookmark set changes (the
model's DebugInfo/References are set before the text, so the document-change
hook sees them current).
CanToggleBookmarkAtLine, called for every gutter line the pointer moves over,
built a full bookmark including a captured editor view state -- a foldings
snapshot, scroll offsets, and a tree-path walk -- only to test it for null. It
now does an anchor-only check; the view state is captured only when a bookmark
is actually created.

After scrolling to a navigated bookmark, the deferred apply restored the
caret/scroll captured when the bookmark was created, which overwrote the
centering that had just been computed for the resolved line. A bookmark
re-anchors by token / IL offset, so a decompiler-setting change that reflows
the C# moves it to a different line than the one saved in its view state; the
stale offset then scrolled that line back off-screen, leaving only the
highlight playing where it could not be seen.
Restore just the captured foldings now -- and before centering, since
collapsing or expanding shifts where lines sit -- and let the centered,
re-resolved line be the final caret and scroll position.

Every save reloaded the JSON sidecar into fresh instances and then replaced the
whole observable collection with Clear()+Add(). That dropped and re-added every
bookmark on each toggle or edit: the bookmarks pane keeps its selection by
reference, so it was cleared on every change (leaving the toolbar acting on a
stale or null selection), the grid's scroll reset, and a checkbox/name edit made
from the grid re-entered the DataGrid mid-edit while its ItemsSource was torn
down and rebuilt.
Reconcile in place instead: keep the existing instance for any anchor still
present (refreshing only its editable Name/Enabled), remove anchors that are
gone, and append new ones. A name/enabled edit leaves the membership unchanged,
so it now touches the collection not at all; structural changes touch only the
affected rows. Instance identity is preserved, so the pane's selection and the
gutter's references survive.

Two fixes to the gutter's hover preview, the faint glyph shown on a hovered
bookmarkable line:
A removal click left the pointer hovering the line it had just cleared, so the
hover preview redrew a glyph there immediately and the click looked like a
no-op. The just-removed line's preview is now suppressed until the pointer
leaves that line; a jitter that stays on the same line keeps it hidden, and a
fresh hover after leaving shows it again.
The preview also never actually faded: the glyph is an SvgImage, which paints
through a custom Skia draw operation that ignores DrawingContext.PushOpacity,
so it always rendered fully opaque. The glyph is now rasterized once into a
bitmap, which DrawImage does composite at the pushed opacity.

The text area paints the I-beam across its whole surface, so the bookmark
icon gutter, line numbers, and folding margin inherited it by walking up the
visual tree. Those margins are click targets, not text, so the I-beam read
wrong over them. Force the normal arrow there, re-applying as the line-number
and folding margins come and go with their display settings.

Import read the chosen file through the tolerant sidecar-load path, which maps a
missing, empty, or unparseable file all to an empty list. Replace mode then
cleared the saved list and wrote the empty result back, so picking a corrupt or
non-bookmark JSON file for a Replace import silently destroyed the user's
bookmarks.
Import now reads through TryReadFrom, which distinguishes a valid (possibly
empty) file from a parse/read failure. A failure leaves the live and saved lists
untouched and returns false so the pane can report it; a valid empty file still
legitimately clears the list in Replace mode. The normal sidecar load keeps its
tolerant behavior.

Activating a bookmark only positioned the view when a decompiler tab was
already the active content: the pending bookmark was set on
DockWorkspace.ActiveDecompilerTab, which is null while a metadata table, the
Options page, or the About page is showing. Navigating from there selected and
decompiled the node but opened at the top with no line highlight.
The pending bookmark now travels to the decompiler model that ShowSelectedNode
routes the selection to, and is consumed in the document-apply step alongside
the view-state restore -- mirroring PendingViewState -- rather than reacting to
a property change. The earlier property-change path fired synchronously during
selection, scrolled, then a deferred document apply reset the caret to the top
with nothing left to re-apply. For a node that is already decompiled (re-shown
after an interlude, where no apply step runs) a ScrollToBookmark callback on the
model scrolls the live view directly, mirroring NavigateBookmarkInFile.

Bookmarks now capture and restore the requested decompiler view state, support rendered-line fallback anchors, expose hover and pane location affordances, route bookmark context-menu actions through the clicked offset, and update the JSON sidecar under a mutex so concurrent instances do not overwrite unrelated bookmark edits.

There was no way to mark and return to interesting spots in decompiled
code. This adds a flat (no folders, no labels) bookmark list: toggle on a
line from the context menu, the gutter, or Ctrl+B; see an icon in a new
left-margin gutter that honours a disabled state; and manage the list in a
dockable pane that auto-registers in the Window menu.
Bookmarks anchor by metadata token, never by a raw line number, so they
survive re-decompilation and decompiler-setting changes that reflow the C#
text: a definition line anchors to its token, while a line inside a method
body anchors to the method token plus an IL offset. Recovering an IL offset
needs the decompiler's sequence points, which the normal C# output did not
carry, so they are captured once at the WriteCode chokepoint and stored as a
per-document line/offset map. The map is also what places gutter icons and
scrolls navigation to the exact line.
The list persists to an ILSpy.Bookmarks.json sidecar next to ILSpy.xml; the
path logic is extracted into AppEnv/ConfigurationFiles so the dock layout
sidecar shares it. Navigating to a bookmark loads its assembly from disk if
it dropped out of the list (and only then offers to remove a bookmark whose
file is gone), then centres the line and plays a brief line flash plus a
gutter-icon pulse. Disabled bookmarks stay visible but are skipped by the
next/previous actions.

The IL view renders a macro opcode like ldarg.0 as the mnemonic (an opcode
reference) followed by the index written as a separate clickable local or
parameter reference. AvaloniaEditTextOutput's omitSuffix path used
TrimEnd('.') to drop the index, but the name ends in the index digit, not a
dot, so it was a no-op: the full "ldarg.0" was written and the index appended
again, producing "ldarg.00" (and likewise ldloc.NN / stloc.NN).
PlainTextOutput and the WPF AvalonEditTextOutput strip everything after the
last dot; the Avalonia port regressed this. Restore that behavior. Only the UI
was affected -- ilspycmd and the disassembler tests use PlainTextOutput.

A standalone portable PDB (or raw metadata stream) loads as a metadata-only
MetadataFile, but the tree node was left empty: LoadChildren early-returned for
any kind other than PortableExecutable/WebCIL, so the node showed an expander
over no children. This regressed in the WPF -> Avalonia port, which dropped the
old default switch arm; release/10.1 still populated such nodes with the
metadata table and heap nodes directly. Restore that behavior.

The "Toggle folding" context-menu entry folded the block at the caret, so
right-clicking a fold on a different line than the caret toggled the wrong
block. Record the document offset under the pointer when the text-view menu
opens and expose it on TextViewContext as TextLocation; the folding entry acts
on that offset (falling back to the caret only when no click position was
recorded). The pointer handler now records the offset before the reference
lookup, so a document with foldings but no clickable references still gets a
position.

The Analyze panel showed each signature as a flat string, so the type names
that carry the key information were hard to spot in long Used-By / Uses lists.
Render analyzer entity rows as syntax-highlighted rich text with the type-name
spans emboldened (issue #2164).
Replace Language.GetRichTextTooltip(entity) with a general
GetRichText(entity, conversionFlags, boldTypeNames): the hover tooltip is one
caller, the analyzer pane another. C# colours the signature via
CSharpHighlightingTokenWriter and bolds the type-name colour spans; IL renders
its disassembled header (its signature form), already lexically highlighted;
the base produces plain text. The IL method/type/field header is semantically
the same artifact as the C# signature, so it shares the one method.
Rendering is opt-in: nodes that want rich labels implement IRichTextNode, and
the single shared SharpTreeView cell renders its runs via the new RichNodeText
attached behaviour, falling back to the plain Text otherwise. SharpTreeNode.Text
stays the authoritative plain string, so search, copy and keyboard navigation
are unchanged; analyzer entity nodes derive Text from the same RichText so the
two never diverge.

The "Open from NuGet feed" chooser rendered every result with the default
NuGet logo, even though the feed search already returns each package's own
IconUrl - it was fetched into NuGetPackageInfo and then ignored. The list
looked like a wall of identical icons, unlike the NuGet gallery.
NuGetPackageInfo is an immutable feed DTO bound straight into the ListBox, so
it can't raise PropertyChanged for an icon that arrives later. Rather than
bolt mutability and an Avalonia image type onto that DTO, introduce a thin
per-row view model (NuGetPackageViewModel) that owns an observable Icon
defaulting to the logo and swaps in the real icon once downloaded, plus an
INuGetIconLoader service that fetches and decodes off the UI thread. Icons
are decoded to 64px (rendered at 32) and cached by URL as the in-flight Task
so each URL downloads once and concurrent requests share it; the loader is
held for the command's lifetime so the cache survives reopening the dialog.
A per-search CancellationTokenSource stops a stale result set's downloads
from painting onto rows recycled by the next search. Any failure - non-http
URL, network error, decode error - collapses to null so a dead icon URL just
keeps the default.
Also disable horizontal scrolling on the results list. With it enabled
(the default), rows measured at unbounded width, so the star column stopped
filling the viewport and selecting a row brought the overflow into view -
the list jumped sideways and grew a scrollbar. The row layout is meant to
fit the width (the description wraps/trims), so horizontal scrolling was
never wanted.

Clicking a reference left AvaloniaEdit's selection-drag mode stuck, so a
subsequent mouse move (with no button held) extended a selection.
AvaloniaEdit's SelectionMouseHandler captures the pointer and enters
selection mode on press, and extends the selection on every move while that
mode is active -- it keys off the mode, not whether a button is down. Only
its bubble-phase PointerReleased handler resets the mode and releases the
capture, and that handler early-returns when the event is already handled.
The reference-click handler ran in the tunnel phase and marked the release
handled before AvaloniaEdit saw it, so AvaloniaEdit's cleanup never ran.
Move the release handler to the bubble phase so it runs after AvaloniaEdit
has reset its state. AvaloniaEdit subscribes from the TextArea constructor,
before this view attaches its handlers, so the ordering is deterministic and
navigation can stay synchronous.

Navigating to a target on startup first eagerly loads every relevant
assembly's metadata so the entity search that follows can resolve it.
That pre-load used the throwing GetMetadataFileAsync, so a restored
session that still referenced an assembly whose file had since been
deleted or moved crashed startup with an unhandled
DirectoryNotFoundException instead of simply skipping the gone entry.
Use GetMetadataFileOrNullAsync there: a missing or unreadable assembly
now resolves to null and is skipped, which the entity search already
tolerates (it uses the OrNull variant too).

ILSpy showed the current location only implicitly in the tree selection and kept search in a separate docked pane. The omnibar, modelled on the Files community app and jiripolasek's EditorBar, puts an address-bar atop each decompiler document: a breadcrumb of the node (Assembly > Namespace > Type > Member) whose segments navigate and whose chevrons list child nodes, turning into a search box on typing that reuses the existing search engine. It coexists with the docked search pane and ships off by default behind the Options / Display 'Tab options' EnableOmnibar toggle, which applies live.

moves the Help items into the application menu and drops the _Help

WPF revealed files through the shell COM API (SHOpenFolderAndSelectItems):
selecting several assemblies and choosing "Open Containing Folder" opened
one Explorer window per folder with all of that folder's files selected,
reusing a window already open at the location. The Avalonia port replaced
this with explorer.exe /select, invoked once per file, so revealing N
assemblies spawned N new windows and a single reveal never reused an
existing one.
Restore the shell-COM reveal on Windows behind the existing cross-platform
ShellHelper, grouping the selection by containing folder. macOS keeps a
single Finder "open -R" for the whole selection; Linux, lacking a portable
select-item hook, opens each distinct parent folder once instead of one
window per file. The folder grouping is a pure, unit-tested seam so the
behaviour is verified without launching the OS file manager.
The Windows COM portion is adapted from the pre-Avalonia ShellHelper; its
author's copyright notice is retained per its MIT license.

LoadedAssembly caches one type system per TypeSystemOptions value, but
the consumers disagreed on which one to use: tree nodes and the
metadata navigator resolved through GetTypeSystemOrNull (a separate
default-options instance) and the search built its request with default
settings. Each module could therefore materialise several type systems,
and none of the display surfaces respected settings that change entity
shapes (nullability, tuples, extension methods, ...). WPF routed all of
these through GetTypeSystemWithCurrentOptionsOrNull.
Reintroduce that helper on top of CreateEffectiveDecompilerSettings and
use it in TypeTreeNode, AssemblyReferenceTreeNode, and the metadata
navigator; the search request now derives its settings the same way, so
all of them hit the same cached instance. NamespaceTreeNode.Decompile
enumerates through the type system matching the decompilation options
it was handed.

The Avalonia port gave DecompilationOptions a parameterless constructor
that silently defaults to new DecompilerSettings(). Several paths picked
it up and decompiled with default settings where the WPF version used
the user's current options: tree member filtering (CSharpLanguage.
ShowMember), PDB generation, the single-file / project / solution Save
Code paths, and the DEBUG decompile-all commands.
Promote the live-snapshot logic that was private to DecompilerTabPage-
Model (settings clone + Display-option bridge + toolbar language
version) to SettingsService.CreateEffectiveDecompilerSettings and use
it at every entry point. Remove the parameterless DecompilationOptions
constructor and make SolutionWriter require settings, so reaching for
defaults is an explicit choice rather than a silent fallback - that
default is exactly what masked these regressions. Search deliberately
keeps default settings (it only needs a type system to materialise).

The global:: prefixes existed because the test project's namespace

The Avalonia port had placed the UI app in an ILSpy.* namespace tree,
while the csproj RootNamespace and every prior release (through 10.1)
use ICSharpCode.ILSpy.*. Restoring the historical namespace reduces the
public API diff against release/10.1 for plugin authors and removes the
shadowing that forced global:: qualifiers in the test project. The
Images class and AccessOverlayIcon enum move back into the root
namespace (as in 10.1), since an ICSharpCode.ILSpy.Images namespace
would shadow the Images class for all code inside ICSharpCode.ILSpy.

Windows maps CON, PRN, AUX, NUL, COM1-9 and LPT1-9 to devices -- on many
builds even with an extension appended, so a type named Con made both
whole-project export and the save dialog fail with IOException '\\.\Con'.
CleanUpName only checked for reserved names after re-appending the file
extension, where they never match, and the save-dialog default-name
helpers did not check them at all. The escape appends the underscore to
the base name (con_.txt, not con.txt_) because device-name parsing
ignores everything after the first dot, and is applied per path segment
so reserved directory names produced by namespaces are covered too. The
ILSpy.Tests.Windows fixture verifies on a real Windows filesystem that
the escaped names are creatable.

Reference links navigated on pointer-press, which meant a press-drag
over a link could never select its text -- the press fired navigation
and handled the event before a selection could start. Move navigation

drag past the click threshold, matching the WPF view's mouse-up

Selecting text inside the popup closed it: the selection drag captures
the pointer, so sweeping past the popup edge fired the content's
PointerExited with IsPointerOver already false. The close veto now

Doc-comment crefs in hover tooltips rendered as link-styled but inert
text, and cref resolution was never wired up. Crefs now resolve against
the current tab's assembly list and navigate through the same
NavigateToReferenceEventArgs channel the analyzer uses; href links open
via the TopLevel launcher. Avalonia inlines are not input elements, so
links are hit-testable TextBlocks embedded via InlineUIContainer.
Interactive content also requires the popup to survive the pointer
travelling onto it: the editor's exit handler now tolerates the
overlay-popup enter/exit ordering via the distance corridor, and the
popup closes when the pointer leaves its own content instead.

The WPF app showed the disassembled IL header when hovering a member
reference in IL view, and the opcode's XML documentation when hovering
an instruction. The Avalonia port lost both: ILLanguage fell back to
the base ambience one-liner and the opcode tooltip carried only the
name and encoding. Opcode docs additionally need a modern-.NET source:
the WPF code read the .NET Framework reference-assembly docs, which do
not exist on modern .NET, so MscorlibDocumentation now falls back to
the ref pack parallel to the hosting runtime.

Two failure modes that both showed the user the "no" cursor with no
other feedback:
1. ResolveDropTarget returned null when e.Source had no
SharpTreeViewItem ancestor, so Explorer drops landing in the gap
beneath the last row (or onto an empty list) never reached
SharpTreeNode.InternalDrop.
2. The middle 50% of a row produces a DropPlace.Inside target on the
row's own node. Most concrete SharpTreeNodes inherit the base CanDrop
(returns false), so a literal "drop a .dll onto an assembly row"
refused even though AssemblyListTreeNode happily accepts that payload.
For (1), fall back to (Root, Children.Count, DropPlace.Inside) when no
row is hit. For (2), introduce PickAcceptingTarget which retries with
the empty-space (root) target when the initial CanDrop is false. Both
OnDragOver and OnDrop go through the same picker so the cursor and the
actual drop agree on the outcome. The retry skips when the initial
target already IS the root, so a real refusal still surfaces as "no".
The marker adorner stays hidden for empty-space drops because the
place is always Inside (Item is null for that case); the existing
DropPlace.Inside early return covers it.
DropTarget, DropPlace, and the two new helpers are internal-visible to
the ILSpy.Tests project for the unit tests that assert the fallback
chain.

Frozen tabs each cache their own decompiled output, but the language
change handler only refreshed ActiveDecompilerTab — hard-wired to the
preview tab — and the display-setting refresh only reached the preview
tab's cached content model, so frozen (and floated) tabs kept showing
stale output until manually re-selected. The handler predates the
freeze feature, which introduced multiple sibling decompiler tabs
without widening it.
Both paths now iterate every decompiler tab across all document docks
(the walk CancelPendingOperationsAsync already used, extracted as
AllDecompilerTabs), and the language handler uses Redecompile instead
of the CurrentNode re-assignment hack.

Three follow-ups so the WPF-era ILSpy.xml survives a load-save-load
cycle through the Avalonia host without losing data the user expected
to keep.
Preserve unknown children verbatim. LoadFromXml only interprets a
known set of element names (KnownChildren) and stashes everything
else; SaveToXml re-emits the stash after the known section. The
AvalonDock <DockLayout> blob the WPF host writes is incompatible with
the Avalonia Dock host and we don't want to interpret it, but blank-
ing it on save would discard a WPF user's saved layout the first
time they launched the Avalonia build. The same stash future-proofs
older builds against fields added in newer ones.
Emit the legacy on-disk shape on save. WindowBounds is written as a
CSV body "L,T,W,H" (the WPF Rect TypeConverter format) instead of
Left/Top/Width/Height attributes, and ActiveTreeViewPath <Node>
values are \xNNNN-hex-escaped on write. With both directions of the
conversion in this file a file written by the Avalonia build is
still readable by an older ILSpy 10.x install, and the diff against
a pre-existing ILSpy.xml stays small during the transition.

persisted both: the search-pane mode picker so the user's last
choice survives restarts, and the file path of the auto-loaded
(dependency) assembly the saved tree-path lands in so the restore
can re-open it before walking. The Avalonia code read both into
properties that nothing wrote to. Now SearchPaneModel restores
SelectedSearchMode on construction and writes back on change via
SettingsService, and AssemblyTreeModel walks the selection's
ancestor chain to find the owning AssemblyTreeNode, stores its
LoadedAssembly.FileName when IsAutoLoaded, and re-opens that file
(when it still exists) before RestoreSelectedPathAsync.

The new Avalonia SessionSettings reads WindowBounds as Left/Top/Width/Height
attributes and reads ActiveTreeViewPath node values raw, but ILSpy 10.x wrote
WindowBounds as a CSV element body ("L,T,W,H", the Rect TypeConverter format)
and \xNNNN-hex-escaped every non-letter-or-digit char in each Node value (so
"TomsToolbox.Wpf" round-tripped through XML as "TomsToolbox\x002EWpf"). On
first launch against an existing ILSpy.xml that means the saved window
position resets to the default and the selected tree node never restores --
the escaped path can't match a live node's ToString().
Accept the CSV body when the WindowBounds element has no attributes, and
decode \xNNNN escapes in tree-view node values. Both fall back through the
existing ParseDouble defaults if a piece is missing, so a corrupted entry
won't crash startup.
Lock the shape in with tests against the actual section the WPF host emits,
plus a forward-compat pair confirming LoadFromXml ignores unknown children
(DockLayout, SelectedSearchMode, ActiveAutoLoadedAssembly) and SaveToXml
never echoes them back -- the AvalonDock schema doesn't translate to the
Avalonia Dock host and would otherwise persist forever as dead state.

WPF showed a row Offset column and decoded the Kind GUID into one cell
combining heap offset, friendly name, and raw GUID; the Avalonia table
only carried the bare heap offsets. Offset follows the GetRowOffset
convention every other table uses. Kind is plain text rather than a
hex column plus tooltip so the per-column filter matches the friendly
names.

Selecting a row in the CustomDebugInformation table now previews its
Value blob beneath it, completing WPF row-details parity: state-machine
hoisted local scopes, compilation options, metadata references, and
tuple element names parse into typed sub-grid rows; source-link JSON
shows as text; everything else — unrecognized kinds, embedded source,
and malformed structured blobs — degrades to a hex dump, as in WPF.
The parser switches on the Kind GUID directly via KnownGuids; the
entry deliberately carries no decoded-kind state, leaving that to the
kind-column work that builds on this.

WPF ILSpy used DataGrid row details in three places: the COFF and
Optional header views (flag-bit breakdown of the Characteristics /
DLL Characteristics words, permanently expanded) and the
CustomDebugInformation table (decoded Value blob, visible when
selected). The Avalonia port already carried the data — both header
nodes populate Entry.RowDetails and the column builder skips it — but
nothing displayed it.
ProDataGrid builds the row-details template once per details element
and recycles the built control across rows, swapping only the
DataContext, so a WPF-style template selector would go stale;
MetadataRowDetailsControl re-runs its content factory on every
DataContext change instead. Per-row initial visibility has no
SetDetailsVisibilityForItem equivalent and recycling resets
AreDetailsVisible, so the view re-derives it in LoadingRow. Row
activation now ignores gestures originating inside the details
presenter — selecting text in a details blob must not navigate away.
This lands the infrastructure plus the two header consumers; the
CustomDebugInformation details build on the EmbeddedSource decoding
work and follow with it. ConfigurePage on MetadataTableTreeNode is
the hook that consumer overrides.
