Decompiling the New C# 14 field Keyword

- C# 14 introduces the 'field' keyword, simplifying property implementation by eliminating the need for manual backing fields while allowing custom logic.
- The 'field' keyword is syntactic sugar; the compiler generates a private backing field similar to auto-implemented properties.
- Reflection-based code (e.g., Entity Framework Core, AutoMapper) may break when refactoring to use 'field' due to changes in backing field names.
- The 'field' keyword is restricted to property accessors, meaning direct manipulation of the underlying field outside accessors is not possible.
- Attributes targeting backing fields must use the 'field:' prefix when applied to properties using the 'field' keyword.
- Naming conflicts may arise if 'field' was previously used as an identifier, requiring adjustments like 'this.field' or '@field'.
- The 'field' keyword enhances code conciseness but requires careful refactoring, especially in legacy or reflection-heavy codebases.
