Today, the Pex team is thrilled to announce www.pexforfun.com, a web site that brings code to life. It analyzes small code snippets, and produces a table of interesting input and output values, often uncovering surprising corner cases. The code can be written in C#, Visual Basic, or F#. You do not need to install anything; all the work happens in the cloud. Pex for fun on the web is a radically simplified version of the fully featured Pex Power Tool for Visual Studio.

Go to www.pexforfun.com, which comes with a set of code puzzles. Then click on the “Ask Pex!” button to get the answer yourself. Share your puzzles with your friends.
