ECMA C# and Common Language Infrastructure
Standards
In August, 2000, Microsoft Corporation, Hewlett-Packard and Intel
Corporation co-sponsored the submission of specifications for the Common Language
Infrastructure (CLI) and C# programming language to the international
standardization organization ECMA. As a result, ECMA formed two task groups (TG3
and TG2, respectively) within TC39, its technical committee responsible for
programming languages and application development.
During the next year, the co-sponsor companies, in
conjunction with other ECMA members and guests (including IBM, Fujitsu Software,
Plum Hall, Monash University and ISE), refined these specifications into
standards. In December, 2001, the ECMA General Assembly ratified the 1st edition
of the C# and CLI standards as ECMA-334 and ECMA-335, respectively. A technical
report on the CLI, ECMA TR84, was also ratified.
In late December, 2001, ECMA submitted the standards and
TR to ISO/IEC JTC 1 via the latter's Fast-Track process. The subsequent 6-month
evaluation and comment period resulted in two NO votes (Japan and UK) on the
draft standards, and one NO vote (Japan) on the draft TR. All comments resulting
from this review were considered at a ballot resolution meeting held in October,
2002. The two NO votes on the standards were resolved, making acceptance
unanimous. However, Japan did not change its NO vote on the draft TR (Japan
would like to see a formatted/readable rendering of the CLI class library as
part of the standard, not as a TR; this will be considered for a future
edition).
The ISO/IEC standards and TR will be published in
December, 2002, and will be known formally as ISO/IEC 23270 (C#), ISO/IEC 23271
(CLI) and ISO/IEC 23272 (CLI TR). Equivalent specifications will be adopted as
2nd edition standards and TR by ECMA at its December, 2002, General Assembly.
Work on the next edition of the standards and TR will
begin in January, 2003.

work to date.
