Links to CTPs for the other Studio Express SKUs
There seems to be some confusion about if there are "CTP" versions of the other Express product SKUs (other than SQL Server Express, that is...) There most certainly are, and here's a list of links for them:
As along as these use version 2.0.050110 of the .NET CLR, you should be able to use the February 2005 CTP of SQL Server 2005 Express and Express Manager with them.
And of course, remember: These downloads contain a more recent version of the product than the Beta, however, CTP builds do not go through the same rigourous testing that Beta builds undergo. Therefore, do not install these builds on machines you depend on. The new Community Technology Preview releases of the Express products now require registration and activation within 30 days of first use. This process is simple, free, and it allows us to personalize your experience on MSDN. If the products are not registered and activated within 30 days of first use, they will cease operating.
