Extension method and dynamic object

Question

I am going to summarize my problem into the following code snippet.

List list = new List() { 5, 56, 2, 4, 63, 2 };
Console.WriteLine(li

To expand on Stecya's answer... extension methods aren't supported by dynamic typing in the form of extension methods, i.e. called as if they were instance methods. However, this will work:

dynamic dList = list;
Console.WriteLine(Enumerable.First(dList));

Of course, that may or may not be useful. If you could give more information about why and how you're trying to use dynamic typing, we may be able to help more.
