I've just installed VS 2008 Database Edition to help with managing the new databases for my current project. The DB project templates in VS 2008 DE provide a really clean way of managing all the DB objects and makes it easy to have it all under source control as well.
However I ran into trouble setting up the projects and kept getting the following error: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified).
In typical Microsoft style there's no help attached to that error; Sorry Mac, you're on your own.
A bit of digging around revealed two things: You must specify a target database for your project (if you don't it'll try and connect to the default instance on your machine and that won't work) and you have to enable the SQL Server Express service on your machine as this DB is used by the project for storing comparison data etc.
Most women will claim that men are reluctant to stop for directions and to read the instructions for the gadget they just bought. Maybe so. I didn't bother reading the tutorials on setting up the project. But blimey, it could certainly be made more intuitive!
Anyway, this post is more of a Note To Self - but if it helps you, too, then great!
