Convert SQL query into LINQ query in VB

问题

I would like to know how to convert the SQL query listed below into a LINQ query in VB:

SELECT * FROM
    (SELECT SUM(t.Amt) Tax, g.GenQuoteDetails_Id, g.lastTkdt, g.QuoteDt, g.BaseFareCurrency, g.BaseFareAmt, g.BaseDecPos, g.LowestorNUCFare, g.EquivCurrency, g.EquivAmt, g.EquivDecPos,g.TotCurrency,g.TotAmt,g.TotDecPos,fareinfo_id FROM GenQuoteDetails g
     INNER JOIN TaxData t ON t.TaxDataAry_Id = g.GenQuoteDetails_Id
     GROUP BY  g.GenQuoteDetails_Id, g.lastTkdt, g.QuoteDt, g.BaseFareCurrency, g.BaseFareAmt, g.BaseDecPos, g.LowestorNUCFare, g.EquivCurrency, g.EquivAmt, g.EquivDecPos, g.TotCurrency, g.TotAmt, g.TotDecPos, fareinfo_id) a
INNER JOIN
    (SELECT p.PenFeeAry_Id, r.RsvnRules_Id, p.TkNonRef, fareinfo_id
     FROM PenFee p, RsvnRules R
     WHERE p.PenFeeAry_Id = r.RsvnRules_Id
     GROUP BY p.PenFeeAry_Id, r.RsvnRules_Id, p.TkNonRef,fareinfo_id) b
ON a.fareinfo_id = b.fareinfo_id
