Attempt to attach an auto-named database for .mdf file failed
I am currently building a Web Application Project in Visual Studio 2010 and, until recently, have not needed to use the scaffolded code for Memberships, Users and Roles etc that are stored in the ASPNETDB.mdf database file. I have been running the project on the Visual Studio Web Server, IIS Express (from Visual studio) and also IIS7.5 without a problem.
