Known Issue(s)

Duplicate `PRI` Entry error when running on Windows

.NET MAUI now depends upon Windows App SDK 1.5 which includes changes that require libraries built against previous versions of .Windows App SDK to be recompiled with the latest version. When using an incompatible library, you'll see an error like this:

WINAPPSDKGENERATEPROJECTPRIFILE : error : PRI175: 0x80073b0f - Processing Resources failed with error: Duplicate Entry.
WINAPPSDKGENERATEPROJECTPRIFILE : error : PRI277: 0x80073b0f - Conflicting values for resource 'Files/Microsoft.Maui/Platform/Windows/Styles/WindowRootViewStyle.xbf'

Locate the file obj\Debug\net9.0-windows10.0.19041.0\win10-x64\pri.resfiles and review the dependencies included. For example:

C:\Users\maleib\.nuget\packages\microsoft.maui.controls.compatibility\9.0.0-preview.7.24407.4\lib\net9.0-windows10.0.19041\Microsoft.Maui.Controls.Compatibility.priC:\Users\maleib\.nuget\packages\microsoft.maui.controls.core\9.0.0-preview.7.24407.4\lib\net9.0-windows10.0.19041\Microsoft.Maui.Controls.priC:\Users\maleib\.nuget\packages\microsoft.maui.core\9.0.0-preview.7.24407.4\lib\net9.0-windows10.0.19041\Microsoft.Maui.priC:\Users\maleib\.nuget\packages\syncfusion.maui.core\26.2.10\lib\net8.0-windows10.0.19041.0\Syncfusion.Maui.Core.pri

Solution: (library maintainer) recompile dependencies with the latest version of Windows App SDK, or (app developer) upgrade to a version of the library that is compatible.

Workaround: libraries may add this Directory.Build.targets .
