Common Type System
The common type system defines how types are declared, used, and managed in the runtime, and is also an important part of the runtime's support for cross-language integration. The common type system performs the following functions:
Establishes a framework that helps enable cross-language integration, type safety, and high performance code execution.
Provides an object-oriented model that supports the complete implementation of many programming languages.
Defines rules that languages must follow, which helps ensure that objects written in different languages can interact with each other.
