ASN1C is code generation tool targeted at developers who produce products based on Abstract Syntax Notation One (ASN.1) and XML standards. It is capable of generating code in four different programming languages: C, C++, Java, and C#.

Objective System's ASN1C compiler quickly and reliably translates ASN.1 and/or XML schema (XSD) source specifications into C, C++, C#, or Java source code.
