It is the standardized organizational layout of your application files: including **Program.cs**, **appsettings.json**, **wwwroot**, and your **Controllers/Models/Views** directories.
A standardized structure ensures that any .NET developer in the world can open your project and immediately understand where everything lives. It creates **Consistency** across the entire software industry.
When a developer leaves your company and a new one starts on a Monday morning, he can fix a bug in the Navbar by 2:00 PM because he knows exactly where the Shared/_Layout.cshtml file is located!
Great for large teams, simplifies scaling, and promotes industry standards.
Can feel "Folder-Heavy" for very beginners who just want one simple file.
