How did My Object Get into ASP.NET Page State?
- by Paul Knopf
I know what this error is, how to fix it, etc.
My question is that I don't know why my current page I am developing is throwing this error when I am not using the foo class directly in any way, nor am I setting anything to the viewstate. I am using postbacks alot, but like I said, I am not storing anything in the viewstate etc one integer.
I am using nhibernate if that is relevant.
Any idea why I need to mark this classes as serializable that arent being used? Where should I start investigating?
