LeanderTJW 

A small .NET utility library for composing and managing disposable resources without writing boilerplate classes.

Configuration contracts: every key with its primitive, presence and description, read and validated at once into an immutable snapshot.

Reads Leander.Configuration contracts from IConfiguration, and registers the snapshot and options with dependency injection.

Markdown documentation, contract files, example appsettings.json and contract comparisons for Leander.Configuration contracts.

Named kinds of values: a converter, normalizers and validators, read from strings with every error reported. Usable without configuration.
