     <Description>ReflectorNet is an advanced .NET reflection toolkit designed for AI-driven scenarios. Effortlessly search for C# methods using natural language queries, invoke any method by supplying arguments as JSON, and receive results as JSON. The library also provides a powerful API to inspect, modify, and manage in-memory object instances dynamically via JSON data. Ideal for automation, testing, and AI integration workflows.</Description>
