文件 Reference assemblies

这是什么? Reference assemblies DLL?

Reference assemblies are a type of DLL (Dynamic Link Library) that serve as a set of metadata and type definitions for.NET Framework types, enabling developers to write code against these types without referencing the actual implementation assemblies. These assemblies do not contain any executable code but provide essential information such as class interfaces, properties, methods, and events required for compilation and intellisense support in development environments. They are crucial for ensuring compatibility and maintainability across different versions of the.NET Framework and its libraries.
