System.Data.SQLite

In this code:

            defValue = FindKey(opts, "Journal Mode", "Delete");
            if (String.Compare(defValue, "Default", StringComparison.OrdinalIgnoreCase) != 0)
            {
              cmd.CommandText = String.Format(CultureInfo.InvariantCulture, "PRAGMA journal_mode={0}", defValue);
              cmd.ExecuteNonQuery();
            }

shouldn't "Default" be "Delete"? There might be some other compares that are wrong.

 This bug is still there in 1.0.66.

if (String.Compare(defValue, "Default", StringComparison.OrdinalIgnoreCase) != 0)

should be

 if (String.Compare(defValue, "Delete", StringComparison.OrdinalIgnoreCase) != 0)

Oops!  Sorry.
