Generate C# Classes from Config Object

Application configs have deep nesting: app settings, database credentials, feature flags. This example generates C# classes from a multi-level config structure so you can deserialize configuration files directly in your .NET application.

What You Get

The tool produces:

Root Root class with three top-level sections: App, Database, Features
RootApp class with Name, Version, Debug properties
RootDatabase class with Host, Port, and Credentials nested class
RootDatabaseCredentials class for database auth
RootFeatures class with DarkMode, MaxConnections, and AllowedOrigins list
Proper C# type mappings: string, long, double, bool, List<string>

How to Use

The example loads with a sample application config in C# mode
The nested structure shows how each config section gets its own class
Copy the classes and paste them into your .NET project
Replace with your actual config JSON to generate classes for your project

Real-World Pattern

.NET config libraries like Microsoft.Extensions.Configuration work well with typed classes. Generate classes from your default config, then use JsonSerializer.Deserialize or your config library’s binder to populate them from JSON files, environment variables, or command-line flags.
