From SQL Server date to VB - sql-server

Question

I read a date from a SQL Server database through Entity Framework. I return the result to the web page and it's displayed like this :
Date(-658436400000)
I presume it's something about date format but all my attempt to resolve it lead to an exception.
Here the Entity Framework code in VB:
Public Function getEvenements(noFacture As String, bd As eFacturationEntities) As Array
Dim evenements As Array = (
From e In bd.ItemFactures Where e.NoFacture_cs = noFacture
Select e Select New With {
.noEvenement = e.NoEvenement_cn,
.depart = e.DetailFactures.FirstOrDefault.LieuPRCH,
.arrivee = e.DetailFactures.FirstOrDefault.LieuDest,
.nomBeneficiaire = e.Beneficiaire,
.NAM = e.DetailFactures.FirstOrDefault.NAM,
.dateDeNaissance = FormatDateTime(e.DetailFactures.FirstOrDefault.DateNaissance_dt),
.dateDeTransport = e.DetailFactures.FirstOrDefault.PRCH_dt,
.noAs811 = e.DetailFactures.FirstOrDefault.NoAS811}).ToArray()
Return evenements
End Function

Answer 1

Solution : call .toString on the date before sending it to the client.
.dateDeTransport = e.DetailFactures.FirstOrDefault.PRCH_dt.ToString,
But this solution may cause an Exceptionon on some case :
"LINQ to Entities ne reconnaît pas la méthode 'System.String
ToString()', et cette dernière ne peut pas être traduite en expression
de magasin."} System.Exception
(the french tradcution of VS is unclear ...)
