The SQL Server group at Microsoft has just launched the SQL Server Hosting Toolkit with the release of the Database Publishing Wizard Community Technology Preview 1.
The objective of the SQL Server Hosting Toolkit is to enable a great experience around hosted SQL Server. The Database Publishing Wizard works toward this mission by making it easy to upload a database from a development box up to a shared hoster. In its first incarnation, the Database Publishing Wizard is a command line tool that generates a T-SQL script designed to be executed in the script execution windows provided by most hosters in their database management consoles. In the coming months we'll be adding a GUI, integrating into Visual Studio, and enabling seamless deployment from the tool to an upload service hosters will be able to deploy.
