[Bug][4.0.6]ArgumentNullException occurs for records in .Net 7.0 about objectdumper HOT 5 CLOSED

Thanks for reporting this issue. I'm looking at it right now. I will post a pre-release nuget package as soon as the fix is ready.

from objectdumper.

The nuget pre-release that contains the bug fix for this issue is available here:
https://www.nuget.org/packages/ObjectDumper.NET/4.1.1-pre

Can you @ibs-ts verify if the problem is solved and give feedback, please? I'll release a stable nuget version afterwards.

from objectdumper.

I've tested 4.1.1-pre with our rather complex model and at least the integration tests succeed.
Thank you for the fix.
Of course it requires more testing and benchmarking after the stable version is released to find any issues.

Side note:

After writing the above comment, I had the idea to add a delegate property to the SampleData-class.
This results in a 'wall-of-text'-output. It's not part of this issue, but I add this so you are aware:

var definition = new SampleData() { Name = "Test", Func = (param) => param };

var str = ObjectDumper.Dump(definition, new DumpOptions()
{
    IndentChar = '\t',
    IndentSize = 1,
    LineBreakChar = Environment.NewLine,
    DumpStyle = DumpStyle.CSharp
});

Console.WriteLine(str);

public readonly record struct SampleData
{
    public required string Name { get; init; }
    public Func<object, object> Func { get; init; }
}

Delegate/lambda/expression output might open pandoras box. I've tried this in the past with visitors. But as soon as you inject parameters (external or referenced) it causes headaches.

Okay. Thanks for testing. Let's look at the other problem in a separate issue.
Func<> are always a bit difficult to handle. I can try it with the given code. Do you want to create a new issue?
