Soma just announced DevLabs (http://msdn.microsoft.com/DevLabs), "a site dedicated to [...] software innovations for the developer community".
We are proud that Pex is one of the first projects hosted on DevLabs.
What does that mean for Pex?
Pex for Visual Studio Team System 2010 CTP
At the same time as Pex became a DevLabs project, we made Pex available as a Microsoft Download for Visual Studio Team System 2010. But before you go there to download the latest version of Pex, keep reading and let us explain this in more detail: Right now, if you download Pex from that link, it will only install if you have VS2010 installed. The first CTP ("Community Technology Preview") of VS2010 will be distributed to attendees of this month's Professional Developers Conference (PDC) in Los Angeles. Another reason to go to PDC. As an alternative, you can still use the Microsoft Research Download which does not require VS2010, and works great with VS2008; it is identical in terms of features.
The new Microsoft Download comes under a Microsoft Pre-Release Software License for Pex. This license is different from the Microsoft Research License agreement: It does not explicitly rule out all forms of commercial use.
An excerpt from the new license: "PRE-RELEASE SOFTWARE. This software is a pre-release version. It may not work the way a final version of the software will. We may change it for the final, commercial version. We also may not release a commercial version."
Experiment, evaluate, and then join us in the conversation
As Soma said: "help us determine the direction that these projects should eventually head". As an early adopter, now is the best time for you to try out Pex and give us feedback. The Pex team is very open to suggestions, as Pex is still rapidly evolving.
MSDN Forum for Pex
Pex has now an MSDN Forum, where you can ask questions and start discussions.
