How to fix - Could not compile native assembly file: environment

Anonymous

I am getting compile time errors on newly created .NET MAUI project. After creating project when I run it (without modifying anything) I get below errors

Error XA3006 Could not compile native assembly file: environment.arm64-v8a.ll C:\Program Files\dotnet\packs\Microsoft.Android.Sdk.Windows\33.0.46\tools\Xamarin.Android.Common.targets XA3006 Could not compile native assembly file: typemaps.armeabi-v7a.ll C:\Program Files\dotnet\packs\Microsoft.Android.Sdk.Windows\33.0.46\tools\Xamarin.Android.Common.targets XA3006 Could not compile native assembly file: typemaps.x86_64.ll C:\Program Files\dotnet\packs\Microsoft.Android.Sdk.Windows\33.0.46\tools\Xamarin.Android.Common.targets XA3006 Could not compile native assembly file: environment.armeabi-v7a.ll C:\Program Files\dotnet\packs\Microsoft.Android.Sdk.Windows\33.0.46\tools\Xamarin.Android.Common.targets XA3006 Could not compile native assembly file: typemaps.x86.ll C:\Program Files\dotnet\packs\Microsoft.Android.Sdk.Windows\33.0.46\tools\Xamarin.Android.Common.targets

Please rebuild your project, copy the log information here from output window.

Did you change the system language before creating MAUI project? If so, you can change the system language back and make a test. Do you have read/write permission to access the MAUI project folder? You can change another disk path, then create MAUI project.

Hi, I did not change language. I tried creating project on some other location and also tried providing read/write permission. Still same issue. I want to add here logs but I am not able to put files more than 3MB. I have added logs here https://github.com/dotnet/maui/issues/14531 You can get from there from my comment. File name is MSBuildDiagnosticLog..zip

Did you close window MS Defender or various antivirus programs as the grendello advice? Then rebuild it.

I test your demo, it is running normally in Microsoft Visual Studio Community 2022 (64-bit) - Preview Version 17.5.0 Preview 1.0 This issue is related to IDE, you can report this issue in the victual studio directly.

Same problems me too from May 2023.

I use:

Microsoft Visual Studio Community 2022 (64-bit) - Version 17.5.5

My colluegues have the same problem with this version.

It seems no problem for colluegues with 2019 version but i don't want to downgrade.

I have too a windows pc managed by organization with Antivirus managed and updated by them.

Any solutions?

@Canino, Marco I will suggest you to raise this issue at https://github.com/dotnet/maui

I have already raised it, https://github.com/dotnet/maui/issues/14531

You can upvote my issue and comment on it or raise a new ticket (it will help as if many people facing issue, it will be on priority to fix) If you want to fix this temporary, in csproj file just change .net7.0 to .net6.0 for 3 to 4 places. It will work.
