To properly display posted code, always use the instructions for code formatting in the Markdown Cheatsheet pop-up below the "Add an Answer" area. :arrow_heading_down:   Or watch this video on code formatting.

But a much better way to share code from a workspace is to use the "snapshot" function and post the link it gives you.

The reason this is happening probably has to do with how their workspace is setup to simplify some things. I got this in Visual Studio by declaring numbersGreaterThanTen as an IEnumerable<int>.

So working in Visual Studio is gonna be something like this:

List<int> numbers = new List<int> { 2, 4, 8, 16, 32, 64 }; IEnumerable<int> numbersGreaterThanTen = new List<int>(); numbersGreaterThanTen = from number in numbers where number > 10 select number;
