How would i count the frequency of a number on an List<double> in C#?

Question

I have an IList<double> and i'm trying to find the most frequent value inside the list, as well as the frequency of each of the numbers on the list, but how would it work in a way that I get something like an IDictionary<number, frequency> of each value?

Thanks :)

var dictionary= list.GroupBy(x => x).ToDictionary(x => x.Key, x => x.Count());
