Hi, here is the information you asked
Please specify the following information:
- the version of Entity Framework you are working with;
Entity Framework 6
- the LINQ query you are trying to execute;
the executed query was
Code: Select all
var candidato = unitOfWork.CandidatoRepository.GetSingleOrDefault(
filter: c => c.PessoaID == id,
includeProperties: "Telefones, Enderecos");
Code: Select all
public virtual TEntity GetSingleOrDefault(
Expression<Func<TEntity, bool>> filter = null,
string includeProperties = "")
{
IQueryable<TEntity> query = dbSet;
if (filter != null)
{
query = query.Where(filter);
}
foreach (var includeProperty in includeProperties.Split
(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries))
{
query = query.Include(includeProperty);
}
return query.SingleOrDefault();
}

- the DDL scripts for the corresponding database objects, etc.
I have a table that is related to two other ones, the first one stores the candidates and the two other ones are storing the candidates phone number and adress.
A candidate can have multiple phone numbers and also multiple adresses, configuring a MxN relationship.
With theese information I believe that you guys can simulate the problem
If possible, please send us a small test project, with which this issue is reproducible.
Also, some useful information can be found here.
My problem is exactly the one you linked here, but we are looking for the solution to the problem using LINQ, the one with sql does not solve my problem.
I think the solution is related to maybe making changes on the driver.
