runtime: System.Text.Json does not support constructors with byref parameters.
Description
I have a List of objects whose constructors take ‘in’ parameters of DateTime and TimeSpan.
public class TestClass
{
public TestClass(in DateTime dateTime, in TimeSpan timeSpan)
{
DateTime = dateTime;
TimeSpan = timeSpan;
}
public DateTime DateTime { get; set; }
public TimeSpan TimeSpan { get; set; }
}
When serializing a list of these objects, I am seeing the exception in the title being thrown:
This is specifically being thrown at IEnumerableDefaultConverter.cs line 255:
state.Current.DeclaredJsonPropertyInfo = state.Current.JsonClassInfo.ElementClassInfo!.PropertyInfoForClassInfo;
Unfortunately I have absolutely no clue what the issue is here. I’m hoping you might be able to help.

Thanks for letting us know. Would it be possible for you to rebase onto the current main’s HEAD? I assume that some of the issues that you were seeing will go away by doing so. After rebasing make sure that you do a clean build:
