[iOS] System.NotSupportedException: System.Collections.Immutable.IImmutableList[Type] on physical device

[mcocaroUX]

Current behavior

Encountering a deserialization exception on iOS physical devices with System.Collections.Immutable.IImmutableList[Type] using a DelegatingHandler. The exact error is:
The type 'System.Collections.Immutable.IImmutableList[Type]' is not supported.

This issue does not occur on Android devices or iOS simulators. Any insights or workarounds would be greatly appreciated.

Thanks for the report. This is a .NET behavior specific to iOS and System.Text.Json, and the fact that reflection emit is not supported on iOS. You'll need to use another type, or use a custom type converter, if supported by your scenario.
