c# destructors not called

Question

Based on similar question responded to on Wednesday, January 23, 2019 10:08 PM, running the code attached does not call the destructors using net6, top-level or using Main. Why?

 class Program  
   {  
      public Program()  
      {  
         WriteLine("Cons called");  
      }  
  
      ~Program()  
      {  
         WriteLine("Destructor called");  
      }  
  
      static void Main(string[] args)  
      {  
         WriteLine("Main started");  
  
         DoStuff();  
      }  
  
      static void DoStuff()  
      {  
         Program p1 = new Program();  
         {  
            WriteLine("Block started");  
            Program p2 = new Program();  
            WriteLine("Block ended");  
         }  
      }  
  
   }

Answer 1

@David Stobbe , Welcome to Microsoft Q&A, based on my test, I reproduced your problem.

After checking, I find that Microsoft doc Example has explained it, the specific description as the following:

.NET 5 (including .NET Core) or a later version: There's no output, because this implementation of .NET doesn't call finalizers when the application terminates.    

Hope this could help you.

Best Regards,
Jack
