CShell, open source C# REPL IDE

CShell, the open source C# REPL IDE | Coding4Fun Blog | Channel 9:

"CShell is an interactive C# scripting environment. It allows you to use C# without any fluff right in a console like environment called a read-eval-print-loop (REPL). Your code is directly evaluated and executed in a shell window, no separate executable has to be compiled and then run in a different process. More elaborate code can be written in a C# script and then evaluated as one file, only one line, or a selection. Then, your results can be easily dumped to HTML (like LINQPad) or viewed as a data grid or plotted to a chart."

...the move is the Chinese government's response to Microsoft's recent end to support and security updates for Windows XP, which still runs most government computers.
...the government has "moved to avoid the awkwardness of being confronted with a similar situation again in future if it continues to purchase computers with [a] "foreign OS".


...the first step to supporting a homegrown OS is to promote the use of "Chinese-designed" (Linux based) OS among official users...


Is it time for Microsoft to introduce its own Linux distribution, i.e. "Winux" all with Office and official subscription support, and XP and Live Tiles "themes"...
