I downloaded the July CTP of .NET 3.0, expecting a lengthy install, a few reboots and possible some problems. None of that. In about ten minutes the software was installed and I was already creating a self-issued card. Minutes later I could seamlessly log in to the sandbox and to Kim’s blog (where I could finally post a comment about a previous post).
So it seems that .NET 3.0 July CTP and Cardspace are already showing a great deal of quality. Good work!
