There is no get_Evidence in the stacktrace!

At least on .NET 4.7.2 (release 461814)

Here is an example of a stacktrace from a System.Runtime.Serialization.SerializationException caused by the mentioned issue.

This issue is still present in the documentation as far as I can tell. AppDomainEvidenceFactory.GenerateEvidence calls AppDomain.GetHostEvidence in the not-default-appdomain case, so there won't be a call to the getter for Evidence when an exception is thrown on the cross-appdomain call.
