If your id is a Guid, then I found this solution to be best:

INSERT INTO YourTable (val1, val2, val3) 
OUTPUT inserted.id 
VALUES (@val1, @val2, @val3)

Full demo:

    internal static Guid InsertNote(Note note)
    {
            Guid id;

            using (
                var connection =
                    new SqlConnection(ConfigurationManager.ConnectionStrings["dbconn"].ConnectionString))
            {
                connection.Open();
                using (
                    var command =
                        new SqlCommand(
                            "INSERT INTO Notes ([Title],[Text]) " +
                            "OUTPUT inserted.id " +
                            $"VALUES ('{title}','{text}');", connection))
                {
                    command.CommandType = CommandType.Text;
                    var reader = command.ExecuteReader();
                    reader.Read();
                    id = reader.GetGuid(reader.GetOrdinal("id"));
                }
                connection.Close();
            }

            return id;
    }

I would recommend using a Stored Procedure, but this is for unit testing our repository.
