“This expression causes side effects and will not

Question

I'm getting this message in watch box.
Actually, my expression doesn't have any side effect, and I need to re-evaluate it automatically each time. How can I achieve that?

Answer 1

You can append ",ac" to the watch expression to have it automatically refresh the value

x.ToString(),ac

See http://msdn.microsoft.com/en-us/library/e514eeby.aspx for more information and other format specifiers.
