Hi, I have created a web application for which i tried to change the session timeout value from sharpoint administrator. I have change the value from 60 to 7 mins, but after changing the value my web config got modified(dont know what was modified, i came to know when i saw last updated time) and application is giving following error, unable to evaluate expression because the code is optimized or a native frame is on top of the call stack I have reset the iis and also chaneged the value from 7 to 60 mins but all in vain. Is there any thing that i have missed out. Thanks, Mishigun

Hi, I found that only sessionstate value got modified. I have rollback the changes and replaced the modified webconfig with backup webconfig and application started working again. But still unable to find what went wrong after modifying the timeout value from central administartor. Please provide the inputs. Thanks, Mishigun
