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
: 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.
: 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 low-level technique for generating Intermediate Language (IL) directly at runtime to create brand new types and methods. Key Benefits and Use Cases
: 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.
