## Summary
Adopts ModernUO.Serialization 4.0.0 across the engine. Three commits, reviewable independently:
1. **Package + tool bump to 4.0.0** (`Server.csproj`, `UOContent.csproj`, `dotnet-tools.json`).
2. **Timers → `[DeserializeTimer]`** — the 8 drifting timers (BaseLight, TreasureMapChest, MarkContainer, FillableContainer, DeathRobe, DecayedCorpse, Corpse, BaseEscortable) now store their next tick as **anchored time**: server downtime no longer consumes the remaining delay, and idle-world saves are byte-stable. This changes their wire format, so each class bumps its serialization version with a `MigrateFrom` that replays the old delta-time read through the migration schema (the new `vN.json` files carry `@AnchoredTimer`; the old ones keep `@TimerDrift`, which the generator reads forever). The 2 wall-clock timers (Aquarium, FountainOfLife) keep their exact format via `wallClock: true` — no bump. Restart methods drop their `TimeSpan.MinValue` sentinel checks: v4 invokes them **only when a timer was actually running at save**.
3. **Linkage → field-side declarations** — 175 conversions across 25 files: `[SerializableFieldSaveFlag(order)]`/`[SerializableFieldDefault(order)]` become `[SaveFlag(nameof(...), nameof(...))]` on the field, and `[SerializableFieldChanged(order)]` becomes the `fieldChanged:` argument of `[SerializableField]`. **Wire-neutral: zero migration schemas changed.**
## Verification
- Solution builds with **0 errors, 0 warnings**; all three 4.0.0 packages verified indexed on nuget.org (no local feed needed).
- **835 + 708 tests green.**
- Generated output inspected: old-version content structs replay `ReadDeltaTime` (e.g. `V3Content.DecayTimerNext = reader.ReadDeltaTime()`), current versions write/read anchored time with the gated restart, and the wall-clock classes emit byte-identical `Write`/`ReadDateTime` framing.
- Schema tool run is committed (CI's `git diff --exit-code` schema check passes): exactly the 8 expected new `vN.json` files, nothing else touched.
- The conversion was scripted with a class-scoped resolver (order → same-class `[SerializableField(order)]`/`[SerializableProperty(order)]`); it planned 175/175 with zero ambiguities before applying.
## Notes
- New `MigrateFrom`s use the content structs' provided `XxxDelay` property, matching the pre-existing idiom in Corpse's and TreasureMapChest's older migrations.
- Follow-up candidate (separate PR, wire-neutral, any time): fold the ~150 eligible hand-written `[SerializableProperty]` setters (clamps, post-change side effects) down to `[SerializableField]` with `allowFieldChange`/`fieldChanged` hooks.
### Summary
* Upgrades Serialization Generator to v3. This contains numerous bug fixes and a significant performance improvement.
* Bumps other dependencies.
## Summary
Replaces the basic `publish.cmd`/`publish.sh` scripts with an interactive **BuildTool** — a C# console app using [Spectre.Console](https://spectreconsole.net/) that guides users through publishing, prerequisite checking, and cross-compilation.
### Why
The community found the existing publish scripts unhelpful for newcomers. They worked but didn't walk users through the process, didn't check prerequisites, and provided no feedback when things went wrong.
### What's New
**Interactive BuildTool** (`Projects/BuildTool/`)
- NativeAOT-compiled C# console app with true-color ASCII logo and ModernUO brand gold/silver palette
- Guided publish wizard with step-by-step back navigation (Ctrl+C or menu "Back" to go to previous step)
- Prerequisite checking: .NET SDK version, VC++ Redistributable (Windows), native libraries (Linux/macOS)
- .NET SDK auto-install offer via Microsoft's official install scripts
- Platform detection: Windows 10 vs 11 (build number), macOS codenames, Linux distro + kernel version
- Cross-compilation support: skips native library checks, shows target prerequisites after build
- Non-interactive mode for CI: `--config Release --skip-prereqs`
- Backward-compatible positional args: `publish.cmd release win x64` still works
**Shell Wrappers** (`publish.cmd`, `publish.ps1`, `publish.sh`)
- Try native BuildTool binary first (downloaded from GitHub Releases)
- Fall back to `dotnet run --project Projects/BuildTool` if unavailable
- SDK bootstrapping: offer to install .NET if not found
**CI/CD Updates**
- Build/test workflows target `Projects/Application/Application.csproj` instead of the solution (excludes BuildTool and test projects from publish)
- New `build-tool-release.yml` workflow builds NativeAOT binaries for win-x64, win-arm64, osx-arm64, linux-x64, linux-arm64
- Minimum SDK bumped to 10.0.201 (required for Serialization Generator 2.14.3 / Roslyn 5.3.0)
**Other Changes**
- Solution converted from `.sln` to `.slnx`
- Updated README with interactive mode instructions and deployment guidance

### Summary
* Adds better `SaveFlag` support.
* Fixes `SortedSet` support.
* Adds custom comparer support for `SortedSet`.
* Fixes various bugs.
* Adds support for `struct`, `record`, and `generic` classes.
* Adds support for `readonly` fields by skipping serializaton entirely.
* Adds support for interface fields that inherit ISerializable
* Adds tests.
See: 59a92cc49a
### Summary
* Bumps to .NET 9 with updated dependencies
* Comparing a value type against null is no longer allowed
* CI/CD now uses the version specified in global.json
* Serialization generator updated to .NET 9 with bug fixes, fixes to turkish language, and parallelization
### Summary
Updates the serialization strategy to use `MemoryMappedFile` instead of thick buffers. This has the benefit of being on-par with the current implementation (based on hardware/OS), however won't incur the double-memory issue.
> [!Important]
> **Developer Note**
> The `BinaryFileWriter` and `BinaryFileReader` has been removed in favor of `MemoryMapFileWriter` and `UnmanagedDataReader`
### Summary
- Fixes issues with non-_ISerializable_ objects having bad serialization (Skill/Stat. Mods)
- Fixes issues with MarkDirty and namespaces: https://github.com/modernuo/SerializationGenerator/issues/29
- Fixes missing dirty tracking for some data structures.
- Fixes cascading MarkDirty for non-serializable types that have owners that are also non-serializable types.
### New Codegenned API
When a data structure (Array, List, Dictionary, HashSet, etc) is source generated for serialization, new methods are added which will handle dirty tracking. Use these instead of the built in methods for that data structure.
_All Data Structures_
```cs
public void Clear<PropertyName>();
```
_Lists and Sets_
```cs
public void AddTo<PropertyName>(V value);
public void RemoveFrom<PropertyName>(V value);
```
_Lists_
```cs
public void InsertInto<PropertyName>(int index, V value);
public void RemoveFrom<PropertyName>At(int index);
```
_Dictionaries_
```cs
public void AddTo<PropertyName>(T key, V value);
public void RemoveFrom<PropertyName>(T key);
public void ReplaceIn<PropertyName>(T key, V value);
```
Over time, they will be cleaned up and more variants added such as `bool RemoveFrom<PropertyName>(T key, out V value)`
## BREAKING CHANGE
**Publishing for linux will no longer include runtimes**
## Major Changes
* Adds .NET 7 support.
* Adds ARM64 support (experimental).
* Changes linux support to be open-ended against anything .NET 7 supports.
* Fixes native library resolutions. (Make sure to install `dev` versions of the libraries)
* Updates README
* Adds Ubuntu 22, CentOS 8/9 Stream to CI/CD.
## TODOs:
* Update modernuo.com docs
Closes#1173Closes#1159
* Adds `SerializationProperty` - This will generate the private variable for serialization. Also provides an option `useField` to specify your own. Example:
```cs
[SerializationProperty(0, useField: nameof(_resource)]
```
- [X] Replace serialization generator with nuget
- [X] Replace schema migration with dotnet bool
- [X] Add ability to run migrations in VS/Rider using a project build
