问题
I'm using System.IO.Packaging to create files in a completely managed desktop (Windows Forms) application.
Under certain conditions, the writing of the OPC package raises the "Unable to determine the identity of the domain" exception. I have learned that it is related to Isolated Storage, as the Packaging API sometimes creates temporary data there.
I haven't found a reliable reproduction of this, but I believe it occurs when data is over a certain size (a few megabytes compressed), and perhaps also depending on the type of user account running the application.
What is "the domain"? My AppDomain? What controls its "identity" in a normal windows forms app?
How can I avoid this problem (apart from manually creating the zip archive files without OPC)?
