Hello,
Package version numbering in MAUI is the same as UWP in Windows10.
Referring to the documentation Package version numbering, we could find the following content:
Important
For Windows 10 or Windows 11 (UWP) packages, the last (fourth) section of the version number is reserved for Store use and must be left as 0 when you build your package (although the Store may change the value in this section). The other sections must be set to an integer between 0 and 65535 (except for the first section, which cannot be 0).
And referring to Attributes and Elements, we could find its requirements for formatting.
A version string in quad notation, "Major.Minor.Build.Revision" where Major cannot be "0".
Best Regards,
Alec Liu.
