According to a Microsoft announcement the Express Edition of SQL Server 2008 won't be available until the end of August.
This however turns out not to be entirely true. Itching to try out the new version, I ended up downloading the evaluation version. It turns out that during the installation you get to choose between installing the evaluation and the express versions.
Unfortunately I can't get the management studio to install though (would have loved to try out the new query visualizer). I don't even see it in the install options, and executing the install directly from the DVD throws an error. At least my tool seems to continue to work with the RTM version.
Well what do you know... I'm also on youtube now. Together with several of our team members I'm demoing a custom renderer from the Code Gallery. Check it out!
Here are the links to the samples:
Other samples that you should check out (because I wrote them :-)):
Utility library: Simplifies ADF development for a number of common tasks. For example add a resource in one line of code, or create a redline tool using only a couple lines of code.
If you want know more I'll be working at the Server Showcase at the
ESRI User Conference next week as well as demoing some more samples at the .NET
