c# - Is the List<T>.ForEach() method gone?

Question

I started dabbling in Windows 8 metro recently, and found that one of my old buddies seems to have gone missing.

I tend to use the .ForEach() method more than I use the traditional foreach() construct, and I realized pretty quickly that this method isn't available. For example, this code will not compile under a metro app:

var list = new List<string>();

list.ForEach(System.Diagnostics.Debug.WriteLine);

I've searched to see if I could find any discussion of this, but wasn't able to. Am I just being obtuse, or is it actually gone?

Answer 1

It's indeed gone:

List<T>.ForEach has been removed in Metro style apps. While the method seems simple it has a number of potential problems when the list gets mutated by the method passed to ForEach. Instead it is recommended that you simply use a foreach loop.

Very strangely, however, it makes an appearance in the documentation, in which nowhere does it state that this method isn't supported in .NET for Windows Store apps (formerly .NET for Metro-style apps). Perhaps this is just an oversight on part of the documentation team.
