Is there a “not equal” in a linq join

Question

I am trying accomplish the LINQ query below but I need a \"not equal\" instead of equal, so that filteredEmployees has all employees from groupA minus groupB.

Answer 1

In Entity Framework 6, I've gotten better results using

var filteredEmployees = groupA.Where(a => !groupB.Select(b => b.Name).Contains(a.Name));
