warning XA1040: The NativeAOT runtime on Android is an experimental feature and not yet suitable for production use. File issues at: https://github.com/dotnet/android/issues
Issue
NativeAOT is an experimental runtime option for .NET for Android. When you
enable NativeAOT via $(PublishAot)=true for a supported publish or optimized
build, this warning is emitted to indicate that NativeAOT is not yet suitable
for production use.
The supported runtimes are:
- CoreCLR (the default for Android applications in .NET 11 and later)
- MonoVM, the default for .NET 10 and earlier and available through
$(UseMonoRuntime)=trueonly on supported targets - NativeAOT, selected by
$(PublishAot)=truefor supported publish or optimized builds
In .NET 11 and later, $(UseMonoRuntime)=true is rejected with
NETSDK1242;
it is not an escape hatch from CoreCLR.
Solution
To silence this warning, you can either:
Use a supported runtime by removing
$(PublishAot)=truefrom your project file.Set
$(EnablePreviewFeatures)totruein your project file to acknowledge the experimental nature of NativeAOT.
