Settings with a generated contract

Valiant Settings turns strongly typed configuration models into deterministic schemas. Use the same generated metadata for Options binding, validation, documentation, tooling, or the built-in ASP.NET Core settings explorer—without reflection-based assembly scanning.

using Valiant.Settings;

[ValiantSettings("Payments", configure: true)]
public sealed record PaymentSettings
{
    public Uri? Endpoint { get; init; }

    [ValiantSecret]
    public string? ApiKey { get; init; }
}

One declaration, several uses

Capability	Result
Schema	Model, property, nesting, collection, default, nullability, required, and secret metadata
Options	Generated section-aware Configure<TSettings> registration on opt-in models
Validation	IValidateOptions<TSettings> backed by a generated Valiant validator
UI	Built-in schema explorer and JSON endpoint with safe secret masking
Tooling	IValiantSettingsSchemaProvider for custom consumers
