[1.0.1] - 2025-03-23

Fixed

• TypeExtensions.NotEquals<T>() — Method ignored the this Type type parameter and always compared typeof(T) == typeof(T), returning false in all cases. Now correctly compares the source type against typeof(T).

• Simplified package structure: Merged common extensions into core package
  • Cocoar.Reflectensions.CommonExtensions merged into Cocoar.Reflectensions
• Removed JSON package: No longer provide JSON serialization wrappers
  • Applications should use System.Text.Json or Newtonsoft.Json directly
  • Removes unnecessary abstraction layer

Fixed

Performance

  • string.Reflect().To<int>() ~118ns (was ~155ns) — 1.3x faster via int.Parse()
  • Generic fallback paths remain available for all other conversions
