Describe the bug
When creating .appx packages with makemsix.exe, the resulting internal zip structure differs from packages created with MakeAppx.exe of the Windows 10 SDK. This inconsistency is observed in the sorting of the zip central directory and the order of certain files within the zip stream.
To Reproduce
Steps to reproduce the behavior:
Create a .appx package using makemsix.exe.
Create a .appx package using MakeAppx.exe with the same contents.
Compare the internal zip structure of both packages using 7-zip and zipdump.
Here is a test UWP project that uses C:\Windows\Temp as the base path in the "platforms\windows\build\windows\bld\package.map.txt" file:
miniappx.zip
Expected behavior
The internal zip structure of .appx packages created by makemsix.exe should be consistent with those created by MakeAppx.exe, including the sorting of the zip central directory and the order of files within the zip stream.
Actual Behavior
The zip central directory in packages created by makemsix.exe is unsorted compared to those created by MakeAppx.exe.
The files Properties/Default.rd.xml and resources.pri are added to the zip stream by makemsix.exe in a different order compared to MakeAppx.exe. Note: This doesn't seem to affect other tooling, e. g. osslsigncode.
Tools that were built assuming a MakeAppx.exe zip file structure now fail when using makemsix.exe.
Screenshots
Here is a 7-zip properties page of the makemsix package versus the MakeAppx package:
7-zip reports an “Unsorted_CD”. We can also see that the CRC32, size and therefore file contents of [Content_Types].xml and AppxBlockMap.xml differ.
Here is a zipdump comparison showing the unsorted central directory and showing the different order of the files “Properties/Default.rd.xml” and “resources.pri” that were added to the zip stream by makemsix.
