Decode.Extensions.Options

Utility extensions for the Options Pattern in .NET, ensuring that configurations are not only registered but also present and valid at runtime.

📦 Installation

dotnet add package Decode.Extensions.Options

🛠️ Usage

1. Registering Options with Mandatory Section

The AddValidatedOptions<T> method ensures that the section exists in your appsettings.json. By default, it looks for a section with the same name as the class T.

using Decode.Extensions.Options;

// In Program.cs
builder.Services.AddValidatedOptions<DatabaseSettings>(builder.Configuration);

Validation depth (changed in 2.0.0). Three checks now run, where previously only the first did:

  1. the section must exist — verified immediately, at registration time;
  2. System.ComponentModel.DataAnnotations attributes on T must be satisfied;
  3. that check runs at application start, not on first resolution.

Before 2.0.0 the method only confirmed the section existed and then called Configure, despite its name. A section that was present but missing a [Required] property registered without complaint and failed later at runtime, far from the cause.

public class DatabaseSettings
{
    [Required(ErrorMessage = "ConnectionString is required.")]
    public string ConnectionString { get; set; } = string.Empty;

    [Range(1, 300)]
    public int CommandTimeoutSeconds { get; set; } = 30;
}

A missing ConnectionString now stops the host during startup with an OptionsValidationException naming the offending property.

2. Immediate Configuration Access

Retrieve a configuration value directly from IConfiguration with immediate validation.

MySettings settings = builder.Configuration.GetValidatedSectionValue<MySettings>();

3. Benefit

Avoid "Silent Failures" where your application starts but crashes later because an IOptions<T> was injected with empty values due to a missing section in the configuration provider.
