- Moved assembly extensions to ModUtils.cs
- Work to event service.
NetworkService work
- Added ImpromptuInterfaces package.
- Networking Service work to support NetVars
- Event Service
- Added assemblies references package for script compilation. Updated Roslyn version for compatibility.
- Package Loading work.
Swap Harmony to HarmonyX
- More refactor conversion to FluentResults.
- Updated StylesService to return Results.
- Refactor of PackageService partially complete.
- Made IService.Reset() required to return a Result.
- Moved plugin/assembly related code to their own folder (same namespace).
- Updated interfaces to reflect the use of Result<T>.
- Partial refactor, incomplete.
- Added 'FluentResults' so we can stop using cursed Exception-based flow control in loading code.
- Added 'OneOf' nuget package: https://github.com/mcintyre321/OneOf
for the implementation of the Optional<T> pattern and complex discrete return types instead of cursed enums (see current AssemblyManager.cs).
