## What it is
A fluent, extensible .NET 6+ library for throwing exceptions with customizable guard clauses and argument validation. It provides chainable checks for strings, collections, comparables, enums, and more.

## Use cases
- validate method arguments with guard clauses in C#
- throw custom exceptions with a fluent API
- check strings and collections for null or empty before use
- enforce contract-style assertions in .NET code
- customize exception messages and exception types per check

## When to choose
- you want readable, chainable argument validation in .NET 6+
- you need fully customizable exception types and messages
- you prefer a lightweight library over a full validation framework

## When to avoid
- you need data annotation or model-level validation rather than guard clauses
- your project targets .NET versions below 6
- you want validation results collected instead of exceptions thrown

## Facets
- artifact type: library
- maturity: stable
- function: error-handling, testing
- domain: developer-tools, programming-languages
- platform: dotnet, cross-platform
- tags: guard-clauses, exceptions, fluent-api, argument-validation, assertions, csharp
