A minimal example project.

NOTE: This is the same bug as this one -> https://bugzilla.xamarin.com/show_bug.cgi?id=56312

When running a release build of watchOS application on an Apple Watch device, and also having LLVM and Bitcode enabled (required for App Store releases), the watchOS extension crashes somewhere within System.*, which I've encountered when using the latest version of Newtonsoft.Json (JSON .NET).

Steps to reproduce with the attached sample project:
1. Setup a wildcard bundle id and provisioning profile for a release build
2. Build and deploy the watchOS application to an Apple Watch device
3. Tap the "Crash Me" button inside the application, which should crash the app after a few seconds

My development environment:
- macOS Sierra (10.12.6)
- Visual Studio for Mac (7.1 Preview build 1291, beta channel)

A crash report that has not been symbolicated.

I'll attach a properly symbolicated crash log once I can.

A crash log that has been symbolicated.

Managed to symbolicate the crash log, hopefully it helps.
Comment 3 Rolf Bjarne Kvinge [MSFT] 2017-08-02 12:02:30 UTC
This is a duplicate of bug #58114, which has been fixed for 15.4

The sample crashes even with the fix, but it's a different crash I believe is a problem with the test app:

> 2017-08-02 13:55:17.779 WatchAppCrashTest.watchOS.Extension[215:122910] *** Terminating app due to uncaught exception 'System.ArgumentException', reason: 'Get Method not found for 'StringProperty''

Updated sample project

Fixed several issues with the sample project itself.
Comment 6 Pauli Jokela 2017-08-02 12:40:24 UTC
@Rolf Sorry about that, the sample project itself had a few issues related to linking, assemblies and namespaces. I've fixed those and attached a new sample project and a new symbolicated crash log.

You should now be able to only crash the application on a device, and I _think_ only as a release build.
Comment 7 Rolf Bjarne Kvinge [MSFT] 2017-08-02 15:37:12 UTC
Your updated version of the test app works fine with the upcoming 15.4 release, so this is already fixed.

@Rolf Thanks for confirming! I'm not authorized to see bug #58114, so couldn't tell what it was about.

What are you referring to when you say "15.4"? Also is that upcoming release available through beta/alpha channels yet? Thank you in advance. :)

15.4 is the release after 15.3 (what you're currently using according to the version information you posted).

It's available in the alpha channel as of a few minutes ago: https://releases.xamarin.com/alpha-release-15-4-alpha-1/
