Winsock Packet Editor 2.0 Releases

The Winsock Packet Editor 2.0 version supports two modes of intercepting Winsock packets: SOCKS proxy and process injection NET 4.8 development framework and Visual Studio 2022 integrated development environment, without the need to register assemblies in the global assembly cache (GAC) for remote injection.

The program provides two versions: online installation (with automatic updates) and offline packaging (without automatic updates), which can be downloaded and used according to needs.
