  "account": "PureSharp is a tool designed to bring functional programming concepts into C# development. It uses Roslyn analyzers to enforce rules such as purity, immutability, and safer control flow. Purity means that methods marked as pure should not perform side effects. Immutability involves treating local variables beginning with an underscore as non-reassignable. Fluent conditional expressions can be used with Fluent.If. These rules are enforced by Roslyn analyzers, providing immediate feedback in the IDE, allowing for CI failure on violations, and fitting seamlessly into the normal C# development workflow. The tool prioritizes practicality over mathematical purity, opting-in developers to declare rules they want enforced. PureSharp is open source and available on GitHub.",
  "summary": "C# is a very flexible language, but that flexibility also makes it easy for side effects and mutable state to spread through a codebase. I built PureSharp to bring a few functional-programming ideas into everyday C# development and make them enforceable at compile time.
