Distinct() with lambda?

Question

Right, so I have an enumerable and wish to get distinct values from it.

Using System.Linq, there\'s of course an extension method called Distinct<

Answer 1

This will do what you want but I don't know about performance:

var distinctValues =
    from cust in myCustomerList
    group cust by cust.CustomerId
    into gcust
    select gcust.First();

At least it's not verbose.
