I get this error and i don't know how to solve it. The error is thrown on this method:

public static List<TIPI_RECAPITI> GetTipiRecapiti()
        {
            var query = from q in dbContext.TIPI_RECAPITI
                        orderby q.ID ascending
                        select q;

            return query.ToList<TIPI_RECAPITI>();
        }   

An EntityManager can only execute on a single thread. This EntityManager is authorized to execute on the thread with id=’16’; the requested operation came from the thread with Id=‘12’.

Hi Alex,


What most likely happen is that the EM is created on another thread but is executing query on a different thread.

Well, in general, if you're doing synchronous operations, they stay on the same thread. It's a different story if you're doing asynchronous operations.

If you can upload your project here, I can take a quick look and let you know what's wrong.
