Add C# console application for programmatic WinGet configuration management

[Copilot]

Implements a C# console application that parses JSON configuration files and programmatically applies WinGet DSC configurations for unattended software installations.

Architecture

• Models: Strongly-typed classes for JSON deserialization (AppConfiguration, Application, InstallOptions, ConfigurationSettings)
• Services:
  • ConfigurationValidator: Field-level validation with detailed error reporting
  • ConsoleLogger: Color-coded logging with configurable levels (Debug/Info/Warning/Error)
  • WinGetConfigurationBuilder: Generates WinGet DSC YAML from JSON with OS assertions and Developer Mode support
  • WinGetInstaller: Async process execution with real-time output streaming and error capture
• CLI: Argument parsing, user confirmation prompts, exit code handling

Configuration Format

{
  "applications": [
    {
      "id": "Microsoft.VisualStudioCode",
      "name": "Visual Studio Code",
      "source": "winget",
      "installOptions": { "silent": true, "acceptPackageAgreements": true },
      "description": "Install Visual Studio Code"
    }
  ],
  "configuration": {
    "minOsVersion": "10.0.22631",
    "enableDeveloperMode": true,
    "logLevel": "Information"
  }
}

Usage

dotnet run                                    # Uses apps-config.json
dotnet run -- myconfig.json output.yaml       # Custom paths
dotnet publish -c Release -r win-x64 --self-contained  # Standalone executable

Generated YAML is compatible with winget configure -f <file> --accept-configuration-agreements.

Original prompt

Build a C# console application that parses a JSON file containing application identifiers and installation options, then programmatically applies a WinGet configuration to perform unattended (silent) software installations. Include basic validation, logging, and failure handling.
