While investigating the .NET 6: SingleView app size it has been noticed that:
_mono_aot_corelib_eh_frame is twice as large compared to _mono_aot_mscorlib_eh_frame when comparing:

  • dotnet - version6.0.301-rtm.22263.15 and
  • legacy mono - version 6.12.0

builds of MySingleView app on iOS.

This can be observed in the reports generated by using bloaty showing MySingleView native output breakdown (divided into segments/sections/symbols):
