While researching another product I came across this 2009 tweet<\/a> from Microsoft\u2019s Nikhil Kothari:<\/p>\n

Office 2010 web apps – perhaps one of the most ambitious script# projects!<\/p>\n<\/blockquote>\n

Script#<\/a> is loosely equivalent to the Google Web Toolkit<\/a>, but whereas GWT compiles Java to JavaScript, Script# compiles C# to JavaScript. According to the site:<\/p>\n

Script# is used extensively by developers within Microsoft building Ajax experiences in Windows Live, Office to name just a couple, as well as by a external developers and companies including Facebook.<\/p>\n<\/blockquote>\n

In other words, it does not have the look of a project that you would recommend for production work, interesting though it is. Nor is there much public activity around Script# that I can see, though there is a CodePlex<\/a> site dedicated to improving its JQuery support.<\/p>\n

Seeing Kothari\u2019s tweet though raises several questions. <\/p>\n
