Libmem.NET v2.4.1 is a Windows x64/x86 / .NET 8 official release of the reusable C++/CLI wrapper around the pinned rdbo/libmem native library.

Release highlights

Fixed

  • Keep AssemblyManager.ReadAlignedCode reliable when complete instructions end at a readable page boundary followed by PAGE_NOACCESS; use bounded partial-read decoding without changing CodeLength.
  • Reject stale process identities (PID plus process start time) before remote memory allocation/free, page protection, Hook installation, and module load/unload. Align static and session-Manager paths; add deterministic external-process regression coverage.
  • Make the failed HookHandle.Remove external-process trampoline regression deterministic by setting the still-allocated trampoline page to PAGE_NOACCESS, rather than relying on a freed address staying unreadable.

Compatibility and limitations

  • Compatible 2.4.x maintenance only: unchanged Public API, native libmem revision, Windows x64/x86 / .NET 8 targets, multi-architecture NuGet layout, and existing Hook/VMT/Injector APIs.
  • Process-identity preflights reduce stale-PID risk but do not make native PID-only calls atomic: target exit or PID reuse between validation and the native call remains possible. No handle-bound native redesign is included.
  • No ARM64, AnyCPU, cross-bitness or game-specific features are added.

Platform and compatibility

  • OS / architectures: Windows x64 and Windows x86
  • Managed runtime: .NET 8
  • Native backend: pinned rdbo/libmem revision
  • AnyCPU: not supported; consumers must select x64 or x86 explicitly

Downloads

  • Libmem.NET-windows-x64.zip — runtime package for Windows x64
  • Libmem.NET-windows-x64.zip.sha256 — SHA-256 checksum for the x64 archive
  • Libmem.NET-windows-x86.zip — runtime package for Windows x86
  • Libmem.NET-windows-x86.zip.sha256 — SHA-256 checksum for the x86 archive
  • Libmem.NET.2.4.1.nupkg — one PackageReference package carrying both architectures; nuget.org publication is a separate step

Libmem.NET remains a general-purpose libmem wrapper. Application snapshots, caches, game state, IPC, and other product-specific models belong in consuming projects.
