TblProducts is my main table. I try to add OneToOne relation with other tables
(TblTelevision and TblCellphone). I cant add more than one relation. If I add
it gives incomplete deployment problem. If I remove any one of the OneToOne
relation from TblProducts its works fine.
Is there any mistake in my code
Please help me
