How good is ADO.NET vNext CTP now?

Hi to all,

Some years ago I have made some experiences with ‘ADO.NET vNext CTP’ predecessor ObjectSpaces. Some while ago I also made my experiences with an O/R mapper (EntityBroker) from THONA Software & Consulting Ltd..
No I will give ‘ADO.NET vNext CTP’ a chance.
How good is Microsoft now?
Is ‘ADO.NET vNext CTP’ better than ObjectSpaces? And when YES which changes Microsoft has done?
Use anyone from you ‘ADO.NET vNext CTP’? Productive? J
