Recommended Directory Structure

Organize your source code with product families at the first level, repos underneath:

C:\src\
├── Metalama-2025.1\           # Product family (specific major version)
│   ├── Metalama\              # Main repo
│   ├── Metalama.Premium\
│   ├── Metalama.Documentation\
│   └── Metalama.Samples\
├── Metalama-2026.0\           # Another major version
│   ├── Metalama\
│   ├── Metalama.Premium\
│   └── ...
├── PostSharp.Engineering\     # Cross-product tooling (not version-specific)
│   ├── PostSharp.Engineering\
│   └── PostSharp.Engineering.AISkills\
└── ...

This structure allows:

• Working on multiple major versions simultaneously
• Shared tooling repos outside product families
• Clear separation between version-specific and cross-cutting concerns
