Debugging of variable param array values not possible

I create a simple code

t_DIM_I4 = public ARRAY[1..4] OF System.Int32;

Program = class
public

    class method Main(args: array of String): Int32;        
    begin
      var c, v: t_DIM_I4;

      Test(c, var v);
    
      writeLn('The magic happens here.');
    end;

    class method Test(constant: t_DIM_I4; var variable: t_DIM_I4): Int32;
    begin
        constant[2] := 3;
        variable[2] := 3;
    end;

end;

If I debug this with VS2017 I can examine the values of constant-array. But I have problems with the variable array. I see only a single very long number? I try it with latest stable build 2551.

.NET, I assume?
