I was able to get this connection string to work with SQL Express on the same tutorial.
As a side note. If you're struggling to get the database to auto-create, it could well be because the database user you are using hasn't been given sufficient permissions. I was able to simply go the Security of the SQL Instance (not the database) and amend the Securables of the specific login so that it had the permission to Create Any Database (I didn't Grant any additional rights) and it allows EF4 to do its thing.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
