C# module: Meta Data doesn't support Collections

[AlekseiKrivo]

Description of the problem

Can't store C# Collections via Meta Data. It works with int, string, bool, etc., but whenever I try to save a collection (e.g. List or Dictionary) I just can't retrieve the stored value. Alt.GetMetaData returns false.

Here is my server-side code:

public class Starting : AsyncResource
{
    public Starting() : base(true)
    {}
    public override void OnStart()
    {
        AltAsync.Log("STARTED!");
    }

    public override void OnStop()
    {
        throw new NotImplementedException();
    }
}
public sealed class Test : IScript
{
    public Test()
    {
        AltAsync.Log("-------------------------------------------------");

        var list = new List<string>()
        {
            "Foo",
            "Bar",
        };
        Alt.SetMetaData("TestMetaList", list);
        AltAsync.Log($"TestMetaList key is existing: {Alt.HasMetaData("TestMetaList")}");

        var listObtained = Alt.GetMetaData<List<string>>("TestMetaList", out var metaList);
        AltAsync.Log($"List obtained from meta: {listObtained}");
        AltAsync.Log($"metaList: {metaList}");

        AltAsync.Log("-------------------------------------------------");

        var dic = new Dictionary<string, string>()
        {
            { "Foo", "Bar" },
        };
        Alt.SetMetaData("TestMetaDic", dic);
        AltAsync.Log($"TestMetaDic key is existing: {Alt.HasMetaData("TestMetaDic")}");

        var dicObtained = Alt.GetMetaData<Dictionary<string, string>>("TestMetaDic", out var metaDic);
        AltAsync.Log($"Dictionary obtained from meta: {dicObtained}");
        AltAsync.Log($"metaDic: {metaDic}");

        AltAsync.Log("-------------------------------------------------");

        var number = 1337;
        Alt.SetMetaData("TestMetaNumber", number);
        AltAsync.Log($"TestMetaNumber key is existing: {Alt.HasMetaData("TestMetaNumber")}");

        var numberObtained = Alt.GetMetaData<int>("TestMetaNumber", out var metaNumber);
        AltAsync.Log($"Number obtained from meta: {numberObtained}");
        AltAsync.Log($"metaNumber: {metaNumber}");

        AltAsync.Log("-------------------------------------------------");

        var text = "Any text here...";
        Alt.SetMetaData("TestMetaString", text);
        AltAsync.Log($"TestMetaString key is existing: {Alt.HasMetaData("TestMetaString")}");

        var textObtained = Alt.GetMetaData<string>("TestMetaString", out var metaText);
        AltAsync.Log($"Number obtained from meta: {textObtained}");
        AltAsync.Log($"metaText: {metaText}");

        AltAsync.Log("-------------------------------------------------");
    }
}

And here is the output:

[14:28:53] -------------------------------------------------
[14:28:53] TestMetaList key is existing: True
[14:28:53] List obtained from meta: False
[14:28:53] metaList:
[14:28:53] -------------------------------------------------
[14:28:53] TestMetaDic key is existing: True
[14:28:53] Dictionary obtained from meta: False
[14:28:53] metaDic:
[14:28:53] -------------------------------------------------
[14:28:53] TestMetaNumber key is existing: True
[14:28:53] Number obtained from meta: True
[14:28:53] metaNumber: 1337
[14:28:53] -------------------------------------------------
[14:28:53] TestMetaString key is existing: True
[14:28:53] Number obtained from meta: True
[14:28:53] metaText: Any text here...
[14:28:53] -------------------------------------------------

As you can see, when I was trying to save a collection as Meta Data, I couldn't get the saved value, even though the key was there.

I'm not sure if it's a bug or expected behaviour, but I couldn't find anything about it in docs (https://docs.altv.mp/articles/meta_data.html?q=Meta)

Reproduction steps

1. Just take my C# code from above and start the server.
2. Check the console for output.

Expected behaviour

Able to store collections as Meta Data.
