.net — Metaprogramming In

: The DLR provides a set of services that support dynamic languages (like IronPython or IronRuby) on .NET, enabling objects to "bind" operations at runtime rather than compile-time. Code Generation Tools :

: A text-based template engine used to generate code files based on specific inputs.

Metaprogramming is typically used when it can significantly reduce complexity or eliminate repetitive boilerplate. Common applications include: Book Review: Metaprogramming in .NET - Neward & Associates Metaprogramming in .NET

The .NET framework provides several distinct tools for different metaprogramming scenarios:

Metaprogramming in .NET is the practice of writing code that treats other code as data—allowing a program to inspect, generate, or modify its own structure and behavior. In the .NET ecosystem, this ranges from basic runtime inspection to advanced compile-time code generation. Core Metaprogramming Techniques in .NET : The DLR provides a set of services

: This is the most common entry point for most developers. It allows you to inspect assembly metadata at runtime to discover types, methods, and properties, and even invoke them dynamically.

: These represent code in a tree-like data structure where each node is an expression (e.g., a method call or a binary operation). They are heavily used by LINQ providers to translate C# code into other languages like SQL. Common applications include: Book Review: Metaprogramming in

: Introduced in C# 9, these are a modern form of generative metaprogramming that allows you to hook into the compilation process. They can inspect existing code and "generate" additional C# source files on the fly, reducing boilerplate and moving logic from runtime to compile-time.
