ISO/IEC finishes fast-track standardization
of Ecma standards for C# programming language
and Common Language Infrastructure
Global standards for application development
of Web services and other types of applications completed
by worldwide standards body
Geneva - 2 April 2003:
The International Organization for Standardization
and International Electrotechnical Committee (ISO/IEC)
today jointly published final international standards
enabling the vendor-neutral programming of Web Services.
These standards include C# (pronounced C-Sharp),
an object-oriented programming language, and the Common
Language Infrastructure (CLI) standard as well as the
Common Language Infrastructure (CLI) technical report.
These publications were enabled by Ecma International,
which secured industry support and fast-tracked the
specifications through the relevant ISO procedures.
Specifications for each technology were developed by
Microsoft and co-submitted to Ecma by Microsoft, Intel
"The adoption by ISO/IEC of these Ecma standards is
a defining moment in the history of Ecma International,
a standards setting body formed more than 40 years ago,
and a milestone in the standardization of innovative
programming languages," said Jan van den Beld, Secretary
General of Ecma International.
Mr. van den Beld continued, "Microsoft is to be congratulated
on giving the industry powerful tools to enable vendor-neutral
development of Web Services, which are creating new
opportunities for application developers and enterprises
"We're extremely gratified that ISO/IEC has recognized
C# and the CLI as public standards," said John Montgomery,
director of the Developer and Platform Evangelism Division
at Microsoft Corp. "With the ratification of these two
application and Web service-development standards by
both Ecma International and ISO/IEC, the application
development ecosystem has grown richer. Developers are
enabled with core Web services technologies that are
endorsed by three of the word's most trusted standards
organizations." (See http://msdn.microsoft.com/net/ecma/)
"Intel sees the CLI and C# specifications as instrumental
in fostering innovation and giving developers more choices."
said Colin Evans, Director, System Software Lab, Intel
Research and Development. "For example, Intel's
Open CLI Library will continue to expand the scope and
performance of the standards-based CLI platform".
(The Open CLI Library is available at SourceForge http://sourceforge.net/projects/ocl)
Ximian CTO and Mono Project leader Miguel de Icaza
commented, "The CLI and C# are the most advanced runtime
and development technologies available today. The Ecma/ISO
standardization efforts enable separate implementations
of this platform to interoperate. The Mono project,
for example, is a multi-platform and open source implementation
which builds on these public standards to create a complete,
open source .NET implementation for Unix and Linux systems."
Microsoft released C# in June 2000. In August,
Microsoft, Hewlett-Packard and Intel co-submitted the
specifications for CLI and C# to Ecma International's
programming language technical committee (TC39). The
co-sponsors, together with other Ecma members including
IBM, Fujitsu, Plum Hall and Monash University, and expert
guests including ISE and Ximian, then refined these
specifications for approval as Ecma standards.
In December, 2001, the Ecma General Assembly approved
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 approved. Ecma
then submitted the two standards and the technical report
to ISO/IEC JTC 1 for Fast-Track adoption.
The standards and TR have now been published by ISO/IEC,
and will be known formally as ISO/IEC 23270 (C#),
ISO/IEC 23271 (CLI) and ISO/IEC TR 23272 (CLI TR).
About Ecma International
Since its inception in 1961, Ecma International (Ecma)
has developed standards for information and communication
technology (ICT). Ecma is a not-for-profit industry
association of technology developers, vendors and users.
Industry and other experts work together in Ecma to
complete standards. Ecma then submits the approved work
for approval as ISO, ISO/IEC and ETSI standards. Ecma
offers industry a "fast track" into these
organizations' standardization procedures, through which
high quality standards are rapidly made available for
Main areas of standardization include: Scripting and
programming languages; Optical and Magnetic storage;
High speed interconnects; Safety, Environmental, Acoustical
and Electromagnetic product attributes; Enterprise and
Proximity Communication and Networking; and File and
Volume structures. Publications can be downloaded free
