Using EF6 SQLite with a plugin

Question

I'm implementing an SQLite Database for a plugin using EF6. However, one of my users gets the error "The default DbConfiguration instance was used before the 'SQLiteConfiguration' type was discovered"

Based on this post, I attributed my context with the SQLiteConfiguration as shown below, but that did not help. I know that this particular user is also using other plugins for his main software and I highly suspect that this has something to do with it. The EF6 docs specifically mention the case of a plugin database here, but I have no idea 1) whether I should implement MyProviderServices and MyConnectionFactory myself or whether the System.Data.SQLite library provides those and 2) how that would change my SQLiteConfiguration constructor, i.e. whether to keep the SetProviderFactory and SetProviderServices lines in there.

[DbConfigurationType(typeof(SQLiteConfiguration))]
public class Context : DbContext
{
    public Context() : base(
        new SQLiteConnection { ConnectionString = "some_connection_string"}, true)
    {
    }

    public DbSet<Foo> Foos{ get; set; }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        var sqliteConnectionInitializer = new SqliteDropCreateDatabaseWhenModelChanges<Context>(modelBuilder);
        System.Data.Entity.Database.SetInitializer(sqliteConnectionInitializer);
    }


public class SQLiteConfiguration : DbConfiguration
{
    public SQLiteConfiguration()
    {
        SetProviderFactory("System.Data.SQLite", SQLiteFactory.Instance);
        SetProviderFactory("System.Data.SQLite.EF6", SQLiteProviderFactory.Instance);
        SetProviderServices("System.Data.SQLite",
            (DbProviderServices)SQLiteProviderFactory.Instance.GetService(typeof(DbProviderServices)));
    }
}

Here is my app.config in case it helps. It was entirely autogenerated

Any help would be highly appreciated!
