I have 2 solutions, using EF 6.0 and both use the exact same default configuration. Still, they connect to 2 different data sources!? (localdb)\mssqllocaldb and .\SQLEXPRESS.

**My configuration:**

```html
  <entityFramework>
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework">
      <parameters>
        <parameter value="mssqllocaldb" />
      </parameters>
    </defaultConnectionFactory>
    <providers>
      <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
    </providers>
  </entityFramework>

```

The DbContext is also similar for both:

```
public class PlusUltraContext : DbContext
{
    public PlusUltraContext() : base("PlusUltra")
    {

    }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();

        base.OnModelCreating(modelBuilder);
    }

    public DbSet<Models.Article> Articles { get; set; }
    public DbSet<Models.ArticleComment> Comments { get; set; }
}

```

vs

```
public class InvoicingContext : DbContext
{
    public DbSet<Address> Addresses { get; set; }
    public DbSet<Company> Companies { get; set; }
    public DbSet<Country> Countries { get; set; }
    public DbSet<Currency> Currencies { get; set; }
    public DbSet<Invoice> Invoices { get; set; }
    public DbSet<InvoiceLine> InvoiceLines { get; set; }
    public DbSet<Person> Persons { get; set; }
    public DbSet<Unit> Units { get; set; }

    public InvoicingContext() : base("Invoicing")
    {

    }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
        base.OnModelCreating(modelBuilder);
    }
}

```

However, when I run the Update-Database command, the first project connects to .\SQLEXPRESS, while the other connects to (localdb)\mssqllocaldb

**My Question**

What are some things I can check to see why they behave differently?
