Rob Caron has just reported the news that the December CTP of Team Foundation Server is now available to MSDN Subscribers. (I checked over the weekend and didn’t notice it ) He makes a special note that this CTP version of the product has a number of key limitations consistent with being a CTP release.
The December CTP of Visual Studio 2005 Team Foundation Server is not supported by a Go-Live license and cannot be used for production deployments. Migration from this release to the final RTM product will NOT be supported. Customers requiring a stable release of Team Foundation Server for production use should download Visual Studio 2005 Team Foundation Server Beta 3 Refresh and complete the associated Go-Live license.
