Cross-Language Interoperability

[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

The common language runtime provides built-in support for language interoperability. However, this support does not guarantee that code you write can be used by developers using another programming language. To ensure that you can develop managed code that can be fully used by developers using any programming language, a set of language features and rules for using them, called the Common Language Specification (CLS), has been defined. Components that follow these rules and expose only CLS features are considered CLS-compliant.

This section describes the common language runtime's built-in support for language interoperability and explains the role that the CLS plays in enabling guaranteed cross-language interoperability. CLS features and rules are identified, and CLS compliance is discussed.
