Question

I am not planning to use EF Code First in an MVC Website. I am looking to Utilize it in a App that has a WPF Client.

Projects are setup as

• ContactManager.Core // Contains all
  Entities(dll)
• ContactManager.Data // Contains
  the DataContext and other data
  related Services(dll)
• ContactManager.Services // Business
  components (dll)
• ContactManager.Client // WPF
  Application

I am unable to generate a SQLExpress or SQLCE 4.0 DB. I am more interested in compact version db. I am not getting any error except my unit tests fail because it tries to connect a db that doesnt exist.

Answer 1

I found out the answer 2 Options:

Option 1:

In your DbContext you specify the connection strings in the base constructor:

public class RecetteContext : DbContext
{
    public RecetteContext()
        :base("<YourConnectionString HERE>")
    {
    }

    public DbSet<Categorie> Categories { get; set; }
    public DbSet<Recette> Recettes { get; set; }

    }
}

Option 2:

The one I used, you give you connection string a name in the DbContext base constructor:

public RecetteContext()
    : base("RecettesDatabase")
{            }

And in your App.Config file you add a ConnectionString with the same name:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <connectionStrings>
    <add name="RecettesDatabase"
         connectionString="Data Source=RecettesDB.sdf"
         providerName="System.Data.SqlServerCe.4.0"/>
  </connectionStrings>
</configuration>

Hope it solved your issue!
