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 and to create modified CLI versions. Microsoft provides the Shared Source CLI as a reference CLI implementation suitable for educational use.

History

The Shared Source CLI was initially pre-configured to run on Windows, but could also be built on FreeBSD (version 4.7 or newer), and Mac OS X 10.2. It was designed such that the only thing that needed to be customized to port the Shared Source CLI to a different platform was a thin Platform Abstraction Layer (PAL).

The last 2.0 version of SSCLI was released on March 2006[1], and contains most of the classes and features of version 2.0 of the .NET Framework[2]. Unlike the previous version however, it is only supported on Windows XP SP2. Hacker trying to build SSCLI 2.0 on Vista either failed or could not make .NET programs to run correctly, leading some to think that SSCLI would not be updated anymore[3].

License

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[4].

Most of the .NET framework class libraries are present except for ADO.NET, Windows Forms, Web Forms, and Web Services. Either you or the Rotor community will have to implement these.

My personal view is that the SSCLI project is doomed to spend the rest of its time only officially supporting that which it did when it was first released. If anyone knows any different then let me know. I couldn't find any information on the web hinting that it would be updated if only to support Vista. {{cite web}}: Check date values in: |date= (help)
