NullReferenceException during json serialize of DynamicClass

[BlueBasher]

Here is what to include in your request to make sure we implement a solution as quickly as possible.

1. Description

DynamicClass throws exception when serializing to Json.

2. Exception

NullReferenceException

3. Fiddle or Project

using Newtonsoft.Json;
using System.Linq.Dynamic.Core;
using System.Text.Json.Serialization;

DynamicProperty[] props = new DynamicProperty[] { new DynamicProperty("Name", typeof(string)), new DynamicProperty("Birthday", typeof(DateTime)) };
Type type = DynamicClassFactory.CreateType(props);
DynamicClass dynamicClass = Activator.CreateInstance(type) as DynamicClass;
dynamicClass.SetDynamicPropertyValue("Name", "Albert");
dynamicClass.SetDynamicPropertyValue("Birthday", new DateTime(1879, 3, 14));
Console.WriteLine(dynamicClass);

JsonConvert.SerializeObject(dynamicClass);

Console.ReadLine();

4. Any further technical details

It seems the issue has been fixed in this commit.
This commit has been done a few minutes before creating release 1.2.20 but it is actually not part of that release.
Not sure if this was on purpose but it would be really nice if a new release could be made that includes the bugfix.

The fix is indeed not yet present in the new version.
https://github.com/zzzprojects/System.Linq.Dynamic.Core/blob/master/CHANGELOG.md

I'll also add this example to the unit-test to be sure that it works correct.

Cool, thanks for the info! Do you have any indication when you expect version 1.2.21 to be released?

[StefH]

I'll try to release a new version this weekend.
