I am using the Database first approach and DbContext. I have several inheritance structures (TPH) in my data model. But DbContext only creates one DbSet for the base class, and none for the subclasses. How should I retrieve all Entities of a specified subclass?
I cannot write queries based on the mapping criteria, as i had to remove those fields from the data model.
Can I simply add a new DbSet to the Entities class (partial class) ?

You can add new properties returning
DbSets of your derived types into context's partial class or you can simply use
OfType<DerivedType>() operator when querying sets created by the code generator.
