You will need to parse – these are the most relevant for .NET tooling. 2. Setting Up a .NET Core Project dotnet new console -n Dos2Tool cd Dos2Tool dotnet add package System.Text.Json dotnet add package SharpZipLib # for extracting PAK/LSV compression Recommended: add System.Xml for LSX (XML-like) support. 3. Parsing LSX (Larian XML) Files LSX is a custom XML format. Example root: using System

using (var fs = File.OpenRead("Game.pak")) using (var reader = new BinaryReader(fs))

Here’s a structured, practical guide for integrating modding or game data handling with .NET Core (modern .NET, e.g., .NET 6/8). This is useful for building tools like save editors, mod managers, or data extractors. Divinity: Original Sin 2 & .NET Core – Developer Guide 1. Understanding the Game’s Data Structure DOS2 stores data in several key formats:

using System.Xml; using K4os.Compression.LZ4.Streams; var saveBytes = File.ReadAllBytes("PlayerProfile.lsv"); using var compressedStream = new MemoryStream(saveBytes); using var decompressedStream = new MemoryStream(); using (var lz4 = LZ4Stream.Decode(compressedStream)) lz4.CopyTo(decompressedStream);
