I’m working on a small C# project where I need to organize different types of project files and metadata in a clean, scalable structure. I’m exploring whether to use classes with nested models, a dictionary-based approach, or something more flexible like JSON schemas to handle changing file types. I’m mainly interested in the best practices for designing a structure that stays easy to maintain as the project grows. I work with detailed files in my daily job such as Blueprint Takeoff documents—so I’m trying to apply the same idea of keeping everything well organized and clearly defined inside the application. If anyone has suggestions on ideal patterns, sample structures, or recommended approaches in C#, I’d really appreciate your insights.
