In May we delivered a good Beta 2 for .NET Framework 3.0, Windows Vista and 2007 Microsoft Office System. All work together (my main machine is now Windows Vista and Office 2007) just fine - with some niggles. But nothing major that has affected my productivity - which is good. Howevere there has been enough niggles for me to start looking fwd to the next CTP - and from their Release Candidates.
The good news is in June we got a new CTP of .NET Framework 3.0 and Windows Vista.
June .NET Framework 3.0 represents a release candidate (RC2 infact) for Workflow Foundation which is great news. If Workflow is your primary interest then download the June CTP, SDK and also the RC2 Workflow Extensions http://www.microsoft.com/downloads/details.aspx?FamilyID=63A80A4B-BD27-4124-A2A5-61786ADB626E&displaylang=en. Please note - June CTP is incompatible with Office Beta 2.
For the moment I have decided to stay with Beta 2 - in the main because it matches the conguration of most of our early adopters.
