I'm not sure why you are interested as I have solved my problem, but there are 5 overrides for this method:

ExecSprocScalar(string)
ExecSprocScalar(string, out System.Data.IDbCommand, params System.Data.IDbDataParameter[])
ExecSprocScalar(string, params System.Data.IDbDataParameter[])
ExecSprocScalar(string, string, out System.Data.IDbCommand, params System.Data.IDbDataParameter[])
ExecSprocScalar(string, string, params System.Data.IDbDataParameter[])
