Answer 1

You can use Kros.KORM for bulk operation.

using (var database = new Database("connectionstring ...", "ado client name ..."))
{
    database
       .Query()
       .AsDbSet()
       .BulkUpdate(_data);
}

Or if you do not need to use ORM and have the source data reader available, you can use the SqlServerBulkInsert / SqlServerBulkUpdate or MsAccessBulkInsert / MsAccessBulkUpdate classes to perform bulk operations.

For example:

using (var bulkInsert = new SqlServerBulkInsert("connection string"))
{
    bulkInsert.Insert(reader);
}

You can see comparison with pure ADO.NET commands https://github.com/Kros-sk/Kros.Libs/wiki
