Information

  • OS: Windows 10
  • Version: 0.48.0
  • Terminal: Any
  • Runtime: NET 8 with Publish Trimmed

Describe the bug
A clear and concise description of what the bug is.

To Reproduce
I Tried without success creating a standalone minimal console app to reproduce, but look like trimmer is not removing the same types/properties in the same way in my application.

  • Create a new Console Application with NET8, with PublishTrimmed, SelfContained, PublishSingleFile, PublishReadyToRun.
  • Use ExceptionFormatter with a Exception with a stack trace.
  • ExceptionFormatter can some times throw a System.NullReferenceException when using reflection.
Unhandled exception. System.NullReferenceException: Object reference not set to an instance of an object.

Expected behavior

  • No Exception when Formation a Exception.

Spectre.Console does not yet support AOT, so errors like this are to expected. Pull requests are most welcome.
