The database is not created until it is used for the first time. You must do any of following to trigger database creation:

• Create instance of your context and retrieve or persist any data
• Create instance of your context and call context.Database.CreateIfNotExists()
• Create instance of your context and call context.Database.Initialize(false)
• Create instance of your context and call context.Database.Create()
