how to avoid [Content_Types].xml in .net's ZipPackage class

Question

I wish to know if there is any way to avoid to have a [Content_Types].xml file inside the zip file while using .net\'s ZipPackage

Answer 1

No.

Zip Packages are not (normal) Zip files. They must follow an imposed structure and contain that Content_Types.xml file in the root. ZipPackage = ZipArchive + Structure.

If you want to create (and especially if you want to read) normal Zip archives you will need an extra library, there is no support in the BCL.
