Visual Studio Lab (VSLab) exploits the power of F# and its interactive top level to provide an interactive environment similar to MatLab and Mathematica, in which you can easily create Add-ins and interact dynamically with them inside Visual Studio. Moreover, since F# is a compiled language, the final code can be compiled as a standalone application.
Goal of the project is to provide the basic infrastructure to turn Visual Studio in VSLab, and a number of addins (called viewlets) used to show data and support development of scientific based applications.
Take a look. I assure you that you’ll be impressed.
