将代码优先实体框架指向创建的数据库

Question

I am creating a Code First Entity Framework to create a database to where I point it to. I have an instance of SQL => DESKTOP-98TG6JE\\SQLEXPRESS and another one => DESKTOP-98TG6JE

In my Asp MVC code, my connection string is like so in the Web.config

<connectionStrings>
    <add name="MusicStoreDB" connectionString="Data Source=DESKTOP-98TG6JE;Initial Catalog=MusicStoreDB;User ID=sa;Password=myPassword123" providerName="System.Data.SqlClient" />
</connectionStrings>

and in my MusicStoreDB : DbContext ,

public MusicStoreDB() : base("MusicStoreDB")
{
}

But when I run the program, it creates a database in the DESKTOP-98TG6JE\\SQLEXPRESS named DefaultConnection and on the instance where I want to create the database, no MusicStoreDB database is created. Image of the created database on the wrong instance

Can you please explain it to me why this is happening? Thank you.

Check you connection string name provided in ApplicationDbContext :

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext() : base("MusicStoreDB")
    {
    }
}
