.NET for Android warning XA1040

Example messages

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, this warning is emitted to indicate that NativeAOT is not yet suitable for production use.

The supported runtimes are:

• CoreCLR (default)
• MonoVM, used via $(UseMonoRuntime)=true

Solution

To silence this warning, you can either:

• Use a supported runtime by removing $(PublishAot)=true from your project file.

• Set $(EnablePreviewFeatures) to true in your project file to acknowledge the experimental nature of NativeAOT.
