How to specify database name in Code First?

Question

How do I tell EF what to name the database and where to put it?

If there is no connection string in the Web.Config, it tries to put it in the local SQLEXPRESS Server

As already mentioned, you can declare your connection string inside the config file of your application with a name (let's say "YourDBName") and then pass this to the DbContext base constructor call (I will add this to the answer for providing a complete answer - great answers already given on this).

Alternatively, you can set this programmatically in your DbContext Extension class, using the Database.Connection.ConnectionString property. For instance:

App.config:

DatabaseContext.cs:

public class DatabaseContext : DbContext
    //Link it with your config file
    public DatabaseContext () : base("YourDBName") 
    {
        //And/Or you can do this programmatically.
        this.Database.Connection.ConnectionString = "";
        // More Stuff.....
    }
}
