ISO/IEC 23270:2018

This specification describes the form and establishes the interpretation of programs written in the C# programming language. It describes:
-  The representation of C# programs;
-  The syntax and constraints of the C# language;
-  The semantic rules for interpreting C# programs;
-  The restrictions and limits imposed by a conforming implementation of C#.
This specification does not describe
- The mechanism by which C# programs are transformed for use by a data-processing system;
- The mechanism by which C# applications are invoked for use by a data-processing system;
- The mechanism by which input data are transformed for use by a C# application;
- The mechanism by which output data are transformed after being produced by a C# application;
- The size or complexity of a program and its data that will exceed the capacity of any specific data-processing system or the capacity of a particular processor;
- All minimal requirements of a data-processing system that is capable of supporting a conforming implementation.
