Reproduce Capturing iteration variable issue

Question

I\'m rereading a part from c# 5.0 in Nutshell about the capturing iteration variables (Page 138) and I have tried to reproduce the code bellow on c# 4.0 and c# 5.0 but with n

Answer 1

Because this issue has been fixed in C# compiler 5.0, you can't reproduce it with Visual studio 2012.

You need to use the C# compiler version 4.0 to reproduce the issue which author is trying to explain. With Visual studio 2010 you can reproduce the problem.

Even if you change the Language version in Vs2012, it still won't work. because you're still using the C# 5.0 compiler.
