The problem I have is that I need to update 15000 rows by deleting them and reinsert them. This has to happen in a single transaction. When I remove the rows row by row this is very slow. Inserting goes fine.
Is there a possibility to execute an ExecuteSqlCommand statement in the same transaction as the savechanges of the context with the insert statements?
you should use Entity Framework 6 Power Tools Community Edition fro reverse entity and its relation generations and use your Entity framework as it was in EDMX
