Unable to create new SQL data tables in Visual Studio Express 2012


I have created a new SQL database in my Visual Studio Express 2012 website. This appears in the AppData folder. I can open the database in the Database explorer and now I want to add some empty data tables.

I right click on the Tables folder and select Add New Table. I get the screen (below). When I have finished I click Update and it appears to do something but then the table has not appeared in the Tables folder.

I have also tried clicking the save button, and saving the table manually in the AppData folder, but yet it still does not appear in the Tables folder.

What am I doing wrong please?

Have you tried refreshing the tables list on the right hand side?
