Last change on this file since 11113 was 11113, checked in by ascheibe, 10 years ago

#2153 fixed assembly file version lookup to also work in sandboxes.
FileVersionInfo.GetVersionInfo(..) needs LinkDemand which we don't allow in a Hive sandbox and therefore throws an exceptions. This leads to tasks that get rescheduled or just stay paused on the slave and never get sent back to the server.
