Not very often you find a hedge fund behind an open source project. I guess it makes sense really, as many quants will be happy to mess around in a python shell, having a C# shell will probably play nicer with the rest of the companies infrastructure.
One of their projects is Deedle; an F#/C#-equivalent of the Python 'Pandas' data frame package. Which would in fact make a nice complement to CShell I imagine.
wow, didn't know that. thanks for putting together that list - maybe we should start a list somewhere where people can add, this is definitely super interesting.
