How do I perform an insert to database and return inserted identity with Dapper?

I\'ve tried something like this:

There is a great library to make your life easier Dapper.Contrib.Extensions. After including this you can just write:

public int Add(Transaction transaction)
{
        using (IDbConnection db = Connection)
        {
                return (int)db.Insert(transaction);
        }
}
