[UnconditionalSuppressMessage ("AOT")]
UpdateWe'll probably actually suppress the warnings like: // FIXME: https://github.com/xamarin/xamarin-android/issues/8724
// IL3050 disabled in source: if someone uses NativeAOT, they will get the warning.
#pragma warning disable IL3050
var dynamic = new DynamicMethod (DynamicMethodNameCounter.GetUniqueName (), ret_type, param_types, typeof (DynamicMethodNameCounter), true);
#pragma warning restore IL3050 |

Context: dotnet/android#8758 (comment) Context: dotnet#1192 In 7d1e705 and b8f6f88, we suppressed IL3050, an AOT-related warning with: // FIXME: dotnet#1192 [UnconditionalSuppressMessage ("AOT", "IL3050")] // Problematic code here We don't immediately *plan* to support NativeAOT on Android in .NET 9, so it would be nice if we could suppress the warning *for now*. But if anyone tried to use this code in a NativeAOT context, they could get a warning. So instead we should use: // FIXME: dotnet#1192 #pragma warning disable IL3050 // Problematic code here #pragma warning restore IL3050 This will prevent us from introducing new `IL3050` and related warnings, but if anyone consumes `Java.Interop.dll` from NativeAOT -- they will see the warning.

When setting
$(EnableAotAnalyzer)totrue, there are several warnings we will suppress for now. These will likely work under Mono, but will need to be fixed one day in .NET 10 or some future release that supports NativeAOT.Ignoring AOT warnings like a reasonable place to start, so we can enable the analyzer and not introduce new warnings.
Creating an issue for now, so I can link to this issue from C# code comments.
Requires fixing, at minimum:
