How I tell my project to use the database in project folder

Question

I created database with ef code first. I copied the 2 files that ef created to the project folder DAL.UsersDb.mdf and DAL.UsersDb_log.ldf

Now I want to tell the project to use the new location. I added them to config file but its not working

<add name="UsersDb"
   connectionString="Data Source=(LocalDB)\v11.0;
   initial catalog=UsersDb;
             AttachDBFilename=|C:\Users\HOME\Desktop\MyProject|\DAL.Funcs+DataBase.mdf";
             integrated security=True;  MultipleActiveResultSets=True;  App=EntityFramework"
   providerName="System.Data.SqlClient" />

I got the following Exception:

Cannot open database \\"DAL.UsersDb\\" requested by the login. The login failed.\\r\\nLogin failed for user 'HOME\\598'.

public class UsersDb : DbContext
{
    public DbSet<BE.User> users { get; set; }
}

Answer 1

Set the user on your application pool to "Local System". It has admin rights, it might be able to open the DB.

Answer 2

may be the service user not have access to database, for testing you can pass user name and password in connection string

<add name="UsersDb"
       connectionString="Data Source=(LocalDB)\v11.0;
       initial catalog=UsersDb;
                 AttachDbFilename=|DataDirectory|C:\Users\X7\Desktop\MyProject\DAL.UsersDb.mdf;
                 user id=user;password=pass;  MultipleActiveResultSets=True;  App=EntityFramework"
       providerName="System.Data.SqlClient" />

And in deployment you can save the username and password in code and change connection string in code

code supply the password to a connection string
