I thought I’d expand on the post I made over the weekend, Team Foundation Server on MSDN Subscriber Downloads.
Team Foundation Server shipped last week, and you may want to order and install it today. When we ‘RTM’ a product, that means it is handed-off from the product team to the manufacturing process. Unfortunately, it takes a little bit of time for that process to yield boxes to purchase.
In the interim, you can download Team Foundation Server Trial Edition, which is Standard Edition with a 180–day trial period. This allows you “…to demonstrate and internally evaluate it.” Once you purchase (see How to Buy) the snazzy blue Standard Edition box, or obtain it through some other channel (such as Volume Licensing), you can upgrade your installed Trial Edition to Standard Edition (see Team Foundation Server on MSDN Subscriber Downloads).
If you need to order media for Team Foundation Server Trial Edition, you can visit the Get Visual Studio 2005 Trial site. After you select your region, you’ll be directed to a page for your part of the world where you should be able to order Visual Studio 2005 Team Suite Trial Edition, which includes Team Foundation Server, or you can just order Team Foundation Server (Note - it'll probably take a few weeks before this media contains the RTM bits).
The last I checked, the pages still list Team Foundation Server Beta 3 Refresh, but you should actually receive the RTM version of the software once it is available on disc. We’re working to get the text updated on those pages.
