c# find duplicates in list

Comment

var query = listOfThings.GroupBy(x => x)

.Select(y => new { Element = y.Key, Counter = y.Count() })

.ToList();

Tells you how many times the elements are repeated in a list.
Works very well for a cart of products that doesn't already hold a property
for quantity.

Improve this by creating a seperate class like ProductWithCount that
contains two properties, a Product and a int Counter.
