odd lambda behavior

Question

I stumbled across this article and found it very interesting, so I ran some tests on my own:

Test One:

List actions = new          


        

Answer 1

@Eric Lippert has explained this in great detail in his two-parts article:

• Closing over the loop variable considered harmful
• Closing over the loop variable, part two

It is a must-read article, as it explains the behavior in depth and at implementation-level.
