Hi,
Regarding on the symptom you described, I've searched for some former issues which has the similiar problems. And one possbile cause is that when we use xcopy to update (or deploy) web application's components( assemblies in private bin folder), the old
ones be replaced which cause the asp.net application be restarted. Also, at the same time, the asp.net will request the new assemblies so as to compile new dynamic components. However, if the updated assemlies's count are huge, it may take some times to finish
which cause the components assemlies be locked by some external process such as xcopy.exe. Then, some unexpected exceptions occurs.
Will the problems occur again if you have restart your IIS (also clear the ASP.NET temporary dir)? Also, you can test by do the xcopy work repeatedly to see whether the problems always occur when we do xcopy, if so, the problems is likely caused by the one
I mentioned above.
Thanks.
