The previous version's About page carried a Check-for-updates / Download
button and an "automatically check for updates every week" toggle. Embed
both back into the About output: the button reuses the toolbar banner's
shared UpdatePanelViewModel (same check, same state), and the toggle is
two-way bound to UpdateSettings.AutomaticUpdateCheckEnabled.

DecompilerTextView subscribed to the process-lived ThemeManager.Current.
ThemeChanged in its constructor and never unsubscribed, so every view (one per
decompiler tab) stayed rooted by the singleton for the lifetime of the process
-- a slow leak that, in the headless suite, accumulates views across every test
and adds GC pressure that tips timing-marginal tests. Bind the subscription to
the visual-tree lifetime instead (subscribe on attach, drop on detach); since
Dock hides and re-shows tab content, this also re-subscribes on re-attach, which
the sibling DecompilerTextEditor's subscribe-in-ctor variant does not.
Also quiet MenuIconWiringProbe: it dumped every menu leaf via TestContext.Out on
every run. Collect the leaves instead and name the icon-bearing ones only in the
assertion's failure message, so a passing run is silent.
Search, Analyzer and Debug Steps cluttered the default layout. They now opt out via ExportToolPane.IsVisibleByDefault = false (which BuildToolDock finally honours), so a fresh launch shows just the assembly tree. Each pane keeps its home alignment and is materialised there on demand by ShowToolPane, so opening Search / Analyze surfaces it in the same place as before.
To audit what each UI test actually exercises, every step now snapshots the
live window to <TestFixtureName>/<TestName>_<NN>_<ShortDescription>.png: a
booted frame (emitted automatically by TestHarness.BootAsync), one after each
state-changing action, and one before each assertion. Flip ILSPY_TESTS_VISIBLE=1
to render the filmstrip; it lands under %TEMP%/ilspy-test-captures (overridable
via ILSPY_TEST_CAPTURES).
The step number and fixture/test name are derived automatically so inserting a
breakpoint never renumbers the rest. The identity is recorded up front from the
real ITest in an ITestAction hook rather than read live: NUnit's
TestContext.CurrentContext does not flow onto async continuations, so a capture
after an await would otherwise collide under the ad-hoc context. And when
rendering is off the whole call is a true no-op -- not even a dispatcher pump --
so instrumenting a test can never perturb the navigation/tab timing it asserts
on. Full headless suite stays green.
Nearly every headless UI test opened with the same four-line prologue
(resolve the shared MainWindow, show it, cast its DataContext, wait for the
assembly list), then repeated the corelib lookup, the EnsureLazyChildren +
Children.OfType<T>().Single() drill, the registry single-by-header lookups,
and the open-an-assembly-and-wait dance. The duplication made the intent of
each test hard to see and every signature tweak a suite-wide edit.
Collapse those into TestHarness (BootAsync, OpenAssemblyAsync, GetCommand,
GetEntry) and TreeNavigation extensions (FindCoreLib, GetChild<T>, Expand<T>),
then apply them across the suite. Net ~865 lines of boilerplate removed with
no change in behaviour; the full headless suite stays green.
Matches the WPF behaviour at master:ILSpy/AssemblyTree/AssemblyTreeModel.cs:440
where DEBUG builds get "ILSpy {DecompilerVersionInfo.FullVersion}" so the
developer can tell from a glance which build the running window came from
(especially handy when the avalonia-preview tag floats forward and several
windows are open at once). Release builds keep the bare "ILSpy" title.
The title is bound from MainWindowViewModel.Title (axaml: Title="{Binding
Title}"), so threading the version through the VM is the natural seam --
no axaml change and the bound value can later be made notifying if we
want to mix in the active assembly-list name.

Both menu builders previously ignored the MenuIcon/Icon metadata on
ExportMainMenuCommand and ExportContextMenuEntry: the strings were
preserved through the WPF -> Avalonia port (~12 main-menu commands
declare MenuIcon, plus a handful of context-menu entries), but the
NativeMenuItem and MenuItem instances they fed into had no icon
assignment. Avalonia's toolbar already had a private path-to-image
reflection resolver; this lifts it into Images.cs as a shared helper
so the two menu sites can consume it too.
NativeMenuItem.Icon is Bitmap-typed (macOS NSImage is the platform
target and has no vector form), so the main-menu path rasterises
SVG icons through RenderTargetBitmap at attach-time -- one-time cost
per menu item at boot. MenuItem.Icon accepts any Control, so the
context-menu path keeps the IImage live inside an <Image> control
and preserves vector rendering.
SaveCodeContextMenuEntry and AssemblyTreeNode.ReloadAssembly were
missing Icon metadata even though their main-menu equivalents
declared MenuIcon. Adding Icon = "Images/Save" and "Images/Refresh"
respectively, matching the toolbar/menu sibling. Other context-menu
entries without Icon metadata are intentionally textless: most are
node-type-specific actions (Remove, Copy results, Search MSDN) where
no main-menu sibling exists to inherit an icon mapping from.
The App.axaml separator style selector "MenuItem Separator" only
matched separators nested inside a templated MenuItem (the main-menu
submenu case). ContextMenuProvider adds Separator directly to
ContextMenu.Items between Category groups, where there's no MenuItem
ancestor for the selector to match -- so context-menu separators
rendered with the Simple theme's default near-invisible style.
Extending to "MenuItem Separator, ContextMenu Separator" covers both
surfaces; toolbar and docking-chrome separators stay scoped out.
MenuIconWiringProbe walks the materialised NativeMenu tree post-build
and asserts File > Open has its Icon populated -- regression net for
the metadata-flow path.

The MainMenu UserControl previously built a regular Avalonia Menu of
MenuItems, which on macOS would render inline in the window instead
of in the system menu bar -- not what Mac users expect. Avalonia's
NativeMenu + NativeMenuBar is the cross-platform abstraction: on
macOS the menu is projected into the system bar, on Windows / Linux
NativeMenuBar's presenter renders the same items inline. The MEF
registry, theme submenu, tool-pane toggles, and dynamic tab list all
flow through unchanged; only the leaf widget type swaps from MenuItem
to NativeMenuItem. KeyModifiers.Control is translated to Meta on
macOS so the system menu bar shows Cmd glyphs instead of Ctrl.

Every_ExportToolbarCommand_Resolves_An_Icon used GetField against
ILSpy.Avalonia.Images.Images to verify every [ExportToolbarCommand]'s
ToolbarIcon resolves to a live IImage. Images.Images currently
declares its icons as static readonly fields, but a future refactor
could lazify them into properties (we explored that path earlier in
this session before reverting). Accept either FieldInfo or
PropertyInfo so the test keeps holding under that refactor.

Adds TabPageMenuItem (mirrors ToolPaneMenuItem) and a live ObservableCollection
on DockWorkspace kept in sync with factory.Documents.VisibleDockables. MainMenu
appends a separator + radio-style MenuItem per tab, with Header bound to Title
and IsChecked bound to IsActive. WPF parity for the previously-skipped tabs
section of the Window menu.

Imports the three SVG assets that were missing from `ILSpy.Avalonia/Assets/Icons/`
and registers them in `Images/Images.cs`, so the MEF-injected toolbar buttons
for "Reload all assemblies", "Sort assembly list by name", and "Collapse all
tree nodes" now render their icons instead of falling back to the tooltip text
(`MainToolBar.axaml.cs:226` `ResolveIcon` returned null for these). Adds a
regression test asserting every `[ExportToolbarCommand]`'s `ToolbarIcon`
resolves to a real `IImage` field on the registry.
Two missing toolbar buttons (Manage Assembly Lists, Show Search) and an
incorrect button order; the layout now mirrors WPF MainToolBar.xaml +
InitToolbar exactly. Also fixes an InitializeButtons no-op under
Avalonia.Headless (Loaded never fired; switched to AttachedToVisualTree).

Single assertion guarding the existing IDeferredContentPresentation.DeferContentPresentation
override that keeps tool panes (search, analyzers, debug-steps, …) hot at
startup. Without the opt-out, headless tests can't reach pane descendants
until focus-activation, and the search pane's startup tasks (assembly index
scan etc.) wouldn't kick off until first user interaction.

GrayscaleAwareImage : Image bakes a luma-transformed Bitmap on the disabled
edge (BT.601 weights) and swaps Source. Replaces the blanket Opacity=0.35
setter that was the previous cue. Applied to the static toolbar buttons in
MainToolBar.axaml plus the MEF-built buttons constructed in BuildButton.

Replaces the brittle root.GetVisualDescendants().OfType<T>().Single() / .First()
pattern with a new WaitForComponent<T>() extension that polls until the requested
control is in the visual tree, then returns it. Avalonia.Headless tests routinely
queried the visual tree before lazily-templated panes (DataGrid, dock content)
had materialised, surfacing as intermittent 'Sequence contains no elements'
failures across the suite.

Each tree-expansion, selection change, command execution, async wait and
key/mouse injection inside an [AvaloniaTest] now carries a short imperative
comment on the line above (e.g. "// expand typeNode", "// select methodA",
"// wait for assemblies to load", "// execute aboutCmd"). The comments are
the same scaffolding the manual debug-with-screenshot workflow uses to
follow what's happening at each breakpoint, surfaced into the committed
source so the tests are readable without the breakpoint markers attached.

Adds a leading paragraph describing what each test verifies and Arrange /
Act / Assert markers (split into numbered phases for multi-step tests) so
the intent of each fixture is readable from comments alone.

Added two new headless tests in MainWindowTests:
- Back_Navigation_Restores_Previously_Selected_Node — selects two methods on
Enumerable, executes DockWorkspace.NavigateBackCommand, asserts the original
node is reselected, decompiled text reverts, and the row is centred.
- Opening_Assembly_Adds_It_To_The_Tree — drives the production OpenCommand via
MainMenuCommandRegistry (matched by Resources._Open header), confirms the
new LoadedAssembly appears, the AssemblyTreeNode is reachable by short name,
and SharpTreeNode.IsSelected is set on the freshly opened node.

DecompileAsEnumerableTest exercises the full path: open mscorlib, navigate
to Enumerable.AsEnumerable, render the decompilation, verify text and
verify the row centred in the assembly tree. Writing it surfaced two
pre-existing bugs the manual smoke-test missed:
