Cannot implicitly convert type 'System.Linq.IQueryable' to 'System.Data.Entity.DbSet'

Question

I\'m new in Linq and so I have these situation below.

Now below error during compilation, says Cannot implicitly convert type \'System.Linq.IQuery

Answer 1

It's because _db.Products isn't a query, it is a DbSet.

The second block works because you are casting it to IQueryable, and the last one works because it is an actual query.
