Decompiling one method or property previously required decompiling its
whole type and searching the output, which is wasteful for scripted and
agent-driven use against large assemblies. The new -m|--member option
accepts an XML documentation id string (the syntax of compiler-generated
documentation files and of the UI's --navigateto option) or a metadata
token in 0x06000005 form, resolves it against the main module (with a
bounds check for tokens and distinct error messages for malformed ids,
unknown members, and members of other modules), and prints just that
member through the engine's single-member decompilation path.
The tests seed a new ICSharpCode.ILSpyCmd.Tests project (part of the
XPlat and Desktop solution filters and of the per-project CI test
steps), driving the real Main in-process via InternalsVisibleTo, so
future ilspycmd features have a dedicated home for CLI tests.

Backfills the standard MIT X11 header on hand-written files that never
got one, attributing each to its first-commit author and year from git
history. Code vendored from dotnet/runtime and Humanizr/Humanizer gets
its origin's license lines and a provenance note instead. Generated
files (Resources.Designer.cs, the version-info template), tool-managed
suppression files, and BAML test-case fixtures intentionally stay
header-less.

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.

--list-* printed generic types without their `n arity suffix, yet -t only
accepted the exact reflection name, so a name copied straight from the listing
threw "Could not find type definition". The listing now prints the reflection
name, and -t resolves through a ladder of progressively looser, uniqueness-
checked rules: the engine's exact lookup, an arity- and nesting-separator-
insensitive FullName match, a case-insensitive match, a namespace-less simple
name, and a trailing segment path ("Dictionary.KeyCollection"). The input is
parsed with System.Reflection.Metadata.TypeName and reduced to its underlying
definition first, so assembly qualification, generic arguments, and
array/pointer/byref decorations cannot corrupt the comparison key. An ambiguous
name reports its candidates instead of guessing, and a miss prints name
suggestions and returns EX_DATAERR rather than dumping a stack trace.

The Microsoft.DiaSymReader / .PortablePdb packages pull NETStandard.Library
1.6.1, which drags in 4.3.0 builds of System.Net.Http, System.Private.Uri
and System.Text.RegularExpressions, all carrying known advisories (NU1902/
NU1903). They are framework-provided at runtime on net10.0; pin the patched
4.3.4 / 4.3.2 / 4.3.1 via central transitive pinning so NuGet audit passes.
Enabling transitive pinning also aligns a handful of other transitive
packages to their declared central versions.

Replace the Windows-only .bat helpers (clean / debugbuild / releasebuild /
restore / updatedeps and BuildTools/format) with cross-platform pwsh
scripts at the repo root: restore.ps1, build.ps1 (-Configuration), clean.ps1,
updatedeps.ps1 and BuildTools/format.ps1, alongside the existing publish.ps1.
Enable a packages.lock.json for every project by hoisting
RestorePackagesWithLockFile into the root Directory.Build.props (the four
core libraries set it individually before) and commit the generated locks,
so restores are repeatable and CI can cache packages off them.
Cache the NuGet packages folder in the three setup-dotnet workflows
(build-ilspy, build-frontends, codeql-analysis), keyed on the lock files
per the setup-dotnet caching guidance.
Scope the Debug "Verify package contents" check to the *.filelist outputs
it actually generates. A project's packages.lock.json is keyed only by
(framework, RID), with no host-OS axis, so a lock produced on Linux
legitimately differs from one produced on Windows whenever an OS-conditional
PackageReference applies (Debug+Windows pulls Microsoft.DiaSymReader*). The
Windows restore then rewrites those locks; that churn must not fail a step
whose job is to police the VSIX/MSI file lists.
Also drop the dead ILSpy.BamlDecompiler publish line from
publishlocaldev.ps1, mirroring the earlier publish.ps1 fix.

The portable-PDB writer carried its knobs (no-logo, pdb id, progress,
progress title) as a growing list of optional WritePdb parameters.
Turn the type into a configured instance whose options are properties,
and add EmbedSourceFiles (default true): when a PDB is generated next
to a project export whose .cs are already on disk, embedding the source
again is redundant, so the caller can turn it off. The per-document
checksum/hash is computed either way, so documents still resolve.

stdout is the data channel: --resource may be writing a binary payload to
it. Update-check notices on stdout would tail-append to the binary stream
and corrupt extracted files. Move them to stderr (npm/cargo/pip
convention) so meta-output stays out of the data path.
--list-resources prints every leaf in the assembly's embedded
resources (including individual entries inside .resources containers).
--resource <name> extracts a single leaf. Names ending in .baml are
decompiled to XAML; everything else is emitted as raw bytes. Without
-o, BAML goes to stdout as text and binary leaves go to the binary
stdout stream. Unknown names exit with EX_DATAERR and print the
available leaves to stderr.
--decompile-baml is a modifier for -p that swaps in the new
BamlAwareWholeProjectDecompiler so .baml entries become .xaml Page
items in the generated project. Default -p behaviour is unchanged.
ResourceExtensions exposes the leaves of an assembly's embedded
resources — including individual entries inside .resources containers
— so callers can list and extract them by a stable path.
BamlAwareWholeProjectDecompiler subclasses WholeProjectDecompiler and
converts .baml entries to .xaml Page items, mirroring the pattern in
ILSpy.BamlDecompiler.BamlResourceFileHandler so PartialTypeInfo flows
through and the C# decompiler suppresses the duplicate Connect()
overrides.
