Thank you for your quick response. I was unaware of the “Compile with .NET Native tool chain” flag.

In case it may help anybody, I used the Runtime Directive builder tool in order to generate the following Default.rd.xml:

<Directives xmlns="http://schemas.microsoft.com/netfx/2013/01/metadata">
  <Application>
    <Namespace Name="Sentry" Serialize="Required All" />
  </Application>
</Directives>

This fixed the problem.

PS: Thank you also for the update regarding OnSuspending too, I adapted on my side too 😃

This came up on another project of mine, and the culprit was System.Text.Json. Sentry uses that as well, so it’s possible that adding System.Text.Json to the runtime directives would help here also. See https://github.com/mattjohnsonpint/TimeZoneNames/issues/92
