My app is losing a datarow session variable for some reason. When I debug, it steps thru normally, then brings up a disassembly window (for some reason), and begins stepping thru that. I'm sure this is somehow causing the variable-loss, but I don't understand what's going on. What could I do that would case this?

Hi,

It seems that your application is using some old/different code that you are not expecting to use. That's why you are not able step in particular method. It shows that you are expecting to execute something from your source code but it is executing some already compiled assembly.

You should ensure that all project references are comming from your expected locations.

Thank you
