Brief history

This International Standard is based on a submission from Hewlett-Packard,

Intel, and Microsoft, that

describes a language called C#, which was developed within Microsoft. The

principal inventors of this

language were Anders Hejlsberg, Scott Wiltamuth, and Peter Golde. The first

widely distributed

implementation of C# was released by Microsoft in July 2000, as part of its

.NET Framework initiative.

ECMA Technical Committee 39 (TC39) Task Group 2 (TG2) was formed in

September 2000, to produce a

standard for C#. Another Task Group, TG3, was also formed at that time to

produce a standard for a library

and execution environment called Common Language Infrastructure (CLI). (CLI

is based on a subset of the

.NET Framework.) Although Microsoft.s implementation of C# relies on CLI

for library and runtime

support, other implementations of C# need not, provided they support an

alternate way of getting at the

minimum CLI features required by this C# standard.

As the definition of C# evolved, the goals used in its design were as

follows:

. C# is intended to be a simple, modern, general-purpose, object-oriented

programming language.

. The language, and implementations thereof, should provide support for

software engineering principles

such as strong type checking, array bounds checking, detection of attempts

to use uninitialized variables,

and automatic garbage collection. Software robustness, durability, and

programmer productivity are

important.

. The language is intended for use in developing software components

suitable for deployment in

distributed environments.

. Source code portability is very important, as is programmer portability,

especially for those

programmers already familiar with C and C++.

. Support for internationalization is very important.

. C# is intended to be suitable for writing applications for both hosted

and embedded systems, ranging

from the very large that use sophisticated operating systems, down to the

very small having dedicated

functions.

. Although C# applications are intended to be economical with regards to

memory and processing power

requirements, the language was not intended to compete directly on

performance and size with C or

assembly language.

The development of this standard started in November 2000.

It is expected there will be future revisions to this standard, primarily

to add new functionality.
