Understanding Project Folder and File Structure

 Example default structure:

MyFirstApi/

│   Program.cs

│   MyFirstApi.csproj

├── Controllers/

│    WeatherForecastController.cs

├── Properties/

│    launchSettings.json

├── appsettings.json

└── appsettings.Development.json

Program.cs → Application startup configuration.

Controllers/ → Contains API endpoints.

appsettings.json → Configuration file.

launchSettings.json → Environment and profile settings.
