Entity Framework DbSet contains 0 records

问题

So I have the following problem:

I have some Vehicle entity that corresponds to a table in the DB. But when I try to retrieve ALL the records with the following line :

var vehicles = db.VehicleSet.ToList();

I get ZERO objects as result ... whilst the table in the DB has approx. 18k records.

Any idea where the problem might be, or is the question too vague?

回答1:

I Figured it out. Turns out it was a problem with the Database. In my structure I was using a "Discriminator" field which was not set and was causing problems.

Thank you for your time.
