CSharpFunctionalExtensions is a functional programming library for C# that provides a framework of monadic containers, pipeline orchestration tools, and immutable domain object patterns. It implements the result pattern to handle operation success and failure as values, reducing the reliance on exceptions for control flow.
The library enables railway-oriented programming by chaining multiple operations into sequences that execute only upon the success of previous steps. It provides specialized wrappers for optional and result types to minimize null checks and nested conditional logic, alongside a base implementation for creating immutable value objects defined by their properties.
The project covers a broad range of functional capabilities, including the aggregation of multiple independent operation outcomes, collection filtering for optional types, and the mapping of functional states to standard HTTP responses for web interfaces. It also includes mechanisms for wrapping functional chains within atomic transactions.
