      "Message": "I've looked into this and could not reproduce the problem you reported.  Enclosed please find some source code that attempts to follow your report.  It references the ZipFile.Entries property, the ZipFile.Entries.Count property, and RequiresZip64.   It does not generate any problems or exceptions. \r\n\r\nIf you can provide a similar source code module that reproduces the problem you saw, I will be able to investigate further.  Attach it to this work item. \r\n\r\nRegarding \"the zip-file remains locked\" - are you using a using() clause?   Instances of ZipFile will remain locked if you do not employ a using clause.\r\n",

      "Message": "Thank you for your reply.\r\n\r\nI wasn't aware of the need to employ the \"using\" thingy.\r\nThat seems to sort out that problem.\r\n\r\nAs for the exception I can see your code working just fine.\r\nHowever if you create a zip file, add one or more entries, removes all entries, and then finally attempts an entry count, that will throw an exception.\r\nI've attached a small example that reproduces the problem.\r\n",
