io non so perché io sono sempre l'eccezione di cui sopra, per favore qualcuno guardarlo ....La data ColumnMapping non corrisponde a nessuna colonna nella origine o di destinazione

Ho avuto lo stesso problema. Nel mio caso, una delle proprietà della classe non aveva una colonna corrispondente nella tabella e non era contrassegnata come ignorata. Una volta aggiunta la colonna, l'errore era scomparso. Spero che questo salvi il tempo di qualcuno. –
C'è un modo per ottenere la mappatura specifica di cui si lamenta? –
