MAUI Firebase iOS not building

Question

I am trying to implement and compile with Visual Studio 2022 in Windows 11 with push notifications in my MAUI application for both Android and iOS. I receive the following error when building: "Unable to copy file "D:\p\xamarin.firebase.ios.installations\8.10.0.3\lib\net6.0-ios15.4\Firebase.Installations.resources\FirebaseInstallations.xcframework\ios-arm64_x86_64-simulator\FirebaseInstallations.framework\Headers\FIRInstallationsErrors.h" to "bin\Debug\net8.0-ios\iossimulator-x64\Firebase.Installations.resources\FirebaseInstallations.xcframework\ios-arm64_x86_64-simulator\FirebaseInstallations.framework\Headers\FIRInstallationsErrors.h". Could not find a part of the path 'bin\Debug\net8.0-ios\iossimulator-x64\Firebase.Installations.resources\FirebaseInstallations.xcframework\ios-arm64_x86_64-simulator\FirebaseInstallations.framework\Headers\FIRInstallationsErrors.h'"

I have already a custom Nuget configuration with a minimal path (D:\p), enabled long paths in the registry and in the 'Local Group Policy Editor'.

Tried to implement Plugin.Firebase --> path too long Tried to implement Plugin.Firebase.CloudMessaging and Plugin.Firebase.Core --> can't build without errors because the path is too long

Answer 1

Hello,

To enable long paths in Windows, in addition to changing the registry, you need to add configuration items to the program.

Please refer to Maximum Path Length Limitation for more details.

The application manifest must also include the longPathAware element.

<application xmlns="urn:schemas-microsoft-com:asm.v3">
    <windowsSettings xmlns:ws2="http://schemas.microsoft.com/SMI/2016/WindowsSettings">
        <ws2:longPathAware>true</ws2:longPathAware>
    </windowsSettings>
</application>

Best Regards,

Alec Liu.

I have solved it by changing the path of bin, obj and nuget packages with D:\b, D:\o, D:\p and now I have installed Plugin.Firebase.CloudMessaging and Plugin.Firebase.Core and can compile
