DbContext and Generics

With DataContext I could do something like 

public IQueryable<T> All()
{
   return db.CreateObjectSet<T>().AsQueryable();
}

(as part of a generic repository class - the rest of the CRUD actions are handled in a similar manner)

I'm looking to see if the same is possible with DbContext : i.e. can a return a Queryable of T? Entry looks a bit like it might help, but not quite... ideas anyone ?

If you wish to return a Queryable would be something like:

public virtual IQueryable GetAll()
{
    return dbContext.Set<T>();
}

In fact, I blogged some time ago about how to create a generic repository using EF4.1 take a look:

Hope I answered your question.

DbSet implements IQueryable

this should work:

public IQueryable All()
{
    return db.Set<T>();
}
