The Shared Source Common Language Infrastructure
(SSCLI), previously codenamed Rotor
, is Microsoft
's shared source
implementation of the CLI
, the core of .NET
. Although the SSCLI is not suitable for commercial use due to its license, it does make it possible for programmers
to examine the implementation details of many .NET libraries, as well as for hackers
to create and use modified CLI versions. Microsoft provides the Shared Source CLI as a reference CLI implementation and expects it to be of real value to students learning cross-platform compiler technologies, class system design guidelines, and so on, being the real-world illustration to their lectures.
The Shared Source CLI was pre-configured to run on Windows, FreeBSD (version 4.7 or newer), and Mac OS X 10.2. It is designed such that the only thing that needs to be customized to port the Shared Source CLI to a different platform should be a thin Platform Abstraction Layer (PAL).
The current version of SSCLI is 2.0, which contains most of the classes and features of version 2.0 of the .NET Framework. Unlike the previous version however, it is only supported on Windows XP SP2.
The Shared Source CLI use the Microsoft Shared Source Common Language Infrastructure license
. This license allows modifications and redistribution of the code for personal or academic usages, but they can't be used for commercial products.
