It seems that Debug.Listeners does not exist in .net core

Question

It seems that Debug.Listeners does not exists in net core2.2

In .net framework, I can use this:

        Debug.Assert(true);
        Debug.Listeners.Add(new TextWriterTraceListener(Console.Out));
        Debug.WriteLine("Debug");

then I can see my debug messages in the console when I debug.
But it can't work in net core, it will give error message like that "Debug does not contain Listeners". I use F12 to search(dotnet core):

public static class Debug
{
    public static int IndentSize { get; set; }
    public static bool AutoFlush { get; set; }
    public static int IndentLevel { get; set; }
    public static void Assert(bool condition);
    public static void Assert(bool condition, string message);
    public static void Assert(bool condition, string message, string detailMessageFormat, params object        public static void Assert(bool condition, string message, string detailMessage);
    public static void Close();
    public static void Fail(string message);
    public static void Fail(string message, string detailMessage);
    public static void Flush();
    public static void Indent();
    public static void Print(string message);
    public static void Print(string format, params object        public static void Unindent();
    public static void Write(string message, string category);
    public static void Write(object value, string category);
    public static void Write(object value);
    public static void Write(string message);
    public static void WriteIf(bool condition, object value);
    public static void WriteIf(bool condition, string message);
    public static void WriteIf(bool condition, string message, string category);
    public static void WriteIf(bool condition, object value, string category);
    public static void WriteLine(object value);
    public static void WriteLine(object value, string category);
    public static void WriteLine(string message);
    public static void WriteLine(string format, params object        public static void WriteLine(string message, string category);
    public static void WriteLineIf(bool condition, object value);
    public static void WriteLineIf(bool condition, object value, string category);
    public static void WriteLineIf(bool condition, string message);
    public static void WriteLineIf(bool condition, string message, string category);
}

It is true I can't find it, at least it is not public.
How can I debug my application just like before?

The offical document(docs.microsoft.com) says that Trace and Debug share the Listeners, but my test result is:

        TextWriterTraceListener myWriter = new TextWriterTraceListener(Console.Out);
        //Debug.Assert(false);    //Assertion Failed
        Trace.Listeners.Add(myWriter);
        Debug.AutoFlush = true;
        Debug.Indent();
        Trace.WriteLine("Trace");   //write Trace
        Debug.WriteLine("Debug");   //Don't write Debug
        Console.ReadLine();

and the example use Debug.Listeners.Add(new TextWriterTraceListener(Console.Out));, but the Debug.Listeners does not exist.

As of .NET Core 3.0, you can use Trace.Listeners instead. It affects Debug too and is functionally equivalent.
