The first great thing is that you can donload and betatest a fully functional version of the Team Suite, either by downloading ISO images -not available yet- or the VPC images (for the latter, you will need to download Virtual PC 2007). I had previously downloaded March CTP's VPC images and everything worked ok.But this time, there's something more, with this release comes the beta builds for the VS Express editions. Although I have not installed VC# Express "Orcas" yet -I'm downloading the installation files as I write this post- it seems we'll be getting an object-relational UML designer tool (probably a lite version of it).
Great news![BTW, does anybody know whether the upcoming release of XNA GSE will support "Orcas" VC# express edition?]
