From the developer:
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.
