Xamarin-macios: [watchOS] "System.NotSupportedException: Stack walks are not supported on this platform" when using arm64_32 arch.

Created on 25 Jun 2019 · 3Comments · Source: xamarin/xamarin-macios

Steps to Reproduce

Create a watchOS project
Set the Release config. architecture to ARMv7k + ARM64_32 for the extension project
Create a PCL project (PCL 4.5 - Profile259) with embeded resource files (localization)
Reference the PCL project (eg: MyApp.Resources)
Deploy (Release) on a real Apple Watch Series 4
Try to call the ResourceManager of the PCL project

Expected Behavior

Deploys fine.
_resourceManager = MyApp.Resources.Strings.Resources.ResourceManager;
or
_resourceManager = Resources.ResourceManager;
should work and give access to the ResourceManager

Actual Behavior

Deploys fine.
An exception occurs when trying to get the ResourceManager.

If the call is inside a try/catch, the exception has no stacktrace/inner:
