Microsoft Research Looks to Extend C#
There are a few pieces of information on Xen floating around the Web. Some characterize Xen as "the hypothetical extension of C#." Others describe Xen as an amalgamation of Microsofts Common Language Runtime (CLR), XML and SQL programming language.
C#, the brainchild of Anders Hejlsberg, a Microsoft distinguished engineer and chief C# language architect, is considered by many as Microsofts alternative to Java.

Microsoft presented a paper on Xen the XML 2003 conference in Philadelphia in December. Microsoft Weblogger Dare Obasanjo provided some notes about the presentation.
"The main thesis of the paper was that heavily used APIs (application programming interfaces) and programming idioms eventually tend to be likely candidates for including into the language," explained Obasanjo.
