Been using it for a while now, both the PDC/March CTP. I'd love to know if subsequent drops of longhorn would come along with vs.net, the latest drop from WinHec did not have vs.net support.

I'm using it, while being not very stable I love to have so that i can start enjoying new features.
Please drop as many preview as possible and post them on MSDN, it is important to see product evolution.

I've been using it extensivelly.

I tried it briefly. If I had had more time I would have played with it more.

Hi Jay,

I just started using it very briefly, little bits and pieces. Once I try to do a full app, I'll probably come back here to tell you what I really think.
A few things I noticed: Ctrl+Shift+B is gone for the build command. I'd like to know why. I use it all the time.
Also I tried to use the new data visualizations when debugging but I couldn't find them. Are they in the CTP?
There is some weirdness when placing controls on a form. For instance, when I try to place a button on the form in the bottom right corner, the form creeps away from the button, as if the button can only be x,y away from the bottom corner of the form. I'm pretty sure that'll be gone, if it isn't already.
A few things I liked: the resource picker dialog. Even though I didn't have any resources for my project and it crashed when I tried to add some, I think that is really good idea. Although I haven't used it yet, Edit and Continue looked awesome at the keynote demo at VSLive. The C# team should definitely take a look at that for the next version of VS.

The other question is, how many people know about the CTP wiki? http://usingvisualstudio.net/flexwiki/
