What is the purpose of PRI files ?

[sigmarsson]

microsoft/microsoft-ui-xaml#8959 has made me inquiry what is happening with pri files as I found this in log :

1>    Index Pass Completed: obj\x64\Debug\net7.0-windows10.0.22621.0\pri.resfiles
1>    WINAPPSDKGENERATEPROJECTPRIFILE : error : PRI175: 0x80073b0f - Processing Resources failed with error: Duplicate Entry.

1>
1>    WINAPPSDKGENERATEPROJECTPRIFILE : error : PRI277: 0x80073b0f - Conflicting values for resource 'Files/Uno.UI.Toolkit/Themes/Generic.xbf'

the pri.resfiles contains these pri files :

This error keeps occuring since Prism 9 pre installed. Something is indeed duplicated with Uno.UI.Toolkit ?
