I am trying to create a SQLite database using entity framework code first.  The application is creating the database for the first time and then seeding the database.  I create a SQLiteConnection and then pass the connection to a Context.  In the constructor of the Context I call Database.SetInitializer<BloggingContext>(new DropCreateDatabaseAlways<BloggingContext>());

I get an exception that says the DeleteDatabase is not supported by the provider.

The following are the supporting classes:
namespace EntityFrameworkConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            var sb = new System.Data.SQLite.SQLiteConnectionStringBuilder();
            sb.DataSource = Path.Combine(Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location), "test.db");
            sb.ForeignKeys = true;
            sb.BinaryGUID = true;
            sb.DateTimeFormat = SQLiteDateFormats.ISO8601;
            sb.DateTimeKind = DateTimeKind.Local;
            sb.ToFullPath = true;

            var conn = new SQLiteConnection(sb.ConnectionString);

            using (var context = new BloggingContext(conn))
            {

                context.Blogs.Add(new Blog { Name = "Yet Another Blog #1" });

                context.SaveChanges();

                var blogs = (from b in context.Blogs
                             orderby b.Name
                             select b).ToList();

            }
        }

    }
}
using System.Data.Common;
using System.Data.Entity;

namespace EntityFrameworkConsoleApplication1
{
    [DbConfigurationType(typeof(MyConfiguration))]
    public class BloggingContext : DbContext
    {
        public BloggingContext(DbConnection c):base(c,true)
        {
            Database.SetInitializer<BloggingContext>(new DropCreateDatabaseAlways<BloggingContext>());
        }

        public DbSet<Blog> Blogs { get; set; }

    }
}
namespace EntityFrameworkConsoleApplication1
{
    public class Blog
    {
        public int BlogId { get; set; }
        public string Name { get; set; }
    }
}

            SetProviderFactory("System.Data.SQLite.EF6", SQLiteProviderFactory.Instance);
            Type t = Type.GetType(
                       "System.Data.SQLite.EF6.SQLiteProviderServices, System.Data.SQLite.EF6");
            FieldInfo fi = t.GetField("Instance", BindingFlags.NonPublic | BindingFlags.Static);
            SetProviderServices("System.Data.SQLite", (DbProviderServices)fi.GetValue(null));
        }
