How to Inherit JsonSerializerContext class in VB.net ? (.net6/7)

Question

In the C# project(.net6/7), I can run the following code and successfully output the serialized content.

 public class Test {  
     public string AA { get; set; } = "A";  
     public string BB { get; set; } = "B";  
 }          
 [JsonSerializable(typeof(Test))]      
 public partial class TestContext : JsonSerializerContext  
 {       
 }  
  
var T = new Test();  
var utf8Json = JsonSerializer.SerializeToUtf8Bytes(T, TestContext.Default.Test);  
var s = Encoding.UTF8.GetString(utf8Json);  
Console.WriteLine(s);  
//{"AA":"A","BB":"B"}  

I must Inherit the JsonSerializerContext class,
Because I need to compile it as a Windows native code application (aot). When I not use JsonSerializerContext to directly serialize custom classes under dotnet6/7, The result is null. eg:{}。

Inherit JsonSerializerContext class works well in C #, but it doesn't seem to work in VB.
How can I achieve this in vb.net project（.net6/7）？

Please help me, please post the vb sample code. thanks!

Hi @Haibo Yang ,
You can refer to the document How to use source generation in System.Text.Json.
It is also recommended that you post your problem on the github issue if the document does not help.
