ConfigContraband

Compile-time Options validation for .NET — a Roslyn analyzer that checks BindConfiguration, ValidateOnStart, ValidateDataAnnotations, and appsettings.json against your IOptions types so broken configuration fails in the editor and CI, not production.

Install

  <PackageReference Include="ConfigContraband" Version="0.9.2" PrivateAssets="all" />

dotnet add package ConfigContraband

No runtime dependency. Analyzers run at build time and in supported IDEs. Visible appsettings*.json files are passed automatically via buildTransitive props.

What it catches

Section typos in BindConfiguration(...) / Configure<T>(GetSection(...))
Missing [Required] keys in visible appsettings
Validation without ValidateOnStart() or ValidateDataAnnotations() (including Microsoft's [OptionsValidator] source-generator path)
Nested options that look validated but are skipped
Misspelled JSON keys, strict unknown-key failures, scalar conversion errors, and DataAnnotations constraint failures
Direct IConfiguration reads whose path is missing from visible appsettings

When the analyzer cannot prove a configuration shape statically, it stays quiet.

The CFG001 section-literal code fix now rewrites a const local's initializer instead of inlining a literal at the use site, so every usage of the constant is corrected at once.
