/// to a non-seekable stream (like standard output, or the

//Check to make sure your file streams are closed, and ITpipes/Template Editor/Winrar/7-Zip don't have the template file open. I'm betting you won't find anything.
//If you try closing Visual Studio and running the binary directly I'm betting you won't have this crash occur. Go ahead--try it.

//The XAML designer process (XDesProc.exe) is configured, by default, to populate its ViewModel in the designer UI. This creates a copy of the model--which creates a second
//Ionic.Zip.ZipFile object using the same template file. So when *this* ZipFile object attempts to move the existing template to replace it with an updated file
//the exception is thrown.
//To fix this, disable the following option in the Visual Studio toolbar above:
// Tools -> Options -> XAML Designer -> "Run project code in XAML Designer (if supported)"
//Once that's disabled, restart Visual Studio. Problem solved.
