How can I implement NotOfType in LINQ that has a nice calling syntax?

Question

I\'m trying to come up with an implementation for NotOfType, which has a readable call syntax. NotOfType should be the complement to OfType&l

Answer 1

I've just tried this and it works...

public static IEnumerable NotOfType(this IEnumerable sequence)
    => sequence.Where(x => !(x is TExclude));

Am I missing something?
