Question

I am having troubles inserting entities in linq after deleting them (without submitting the changes).

List<AlergiesPerPersonBE> AlergiesPerPerson = AlergiesPerPersonToInsert;

RepositoryFactory.GetAlergiesPerPersonRepository().DeleteWhere(x => x.PersonId == id);
RepositoryFactory.GetAlergiesPerPersonRepository().Insert(AlergiesPerPerson);

DataContextFactory.SubmitChanges();

Both (delete and insert) don´t submit any changes. They just InsertAllOnSubmit and DeleteAllOnSumbit.

The code works fine the first time. All the details are inserted properly. The second time that I run the same code, all rows of the db are deleted. The third time, all works fine. It works, then it doesn’t, and so on.

Answer 1

Try

...DeleteWhere(x => x.PersonId == id); 
DataContextFactory.SubmitChanges();

...Insert(AlergiesPerPerson);
DataContextFactory.SubmitChanges();

There’s no reason that you have to submit changes only once per unit of work. Note that this will still work with any transactions that you have.
