P \ Invoke:

[DllImport("kernel32.dll")] [return: MarshalAs(UnmanagedType.Bool)] static extern bool AllocConsole();

Call:

 if (AllocConsole()) { // Этот блок выполняется, но текст в консоль не выводится Console.WriteLine("Console Runned!"); }

ps VS 2017RC, when you call not from under VS, everything works stably. What is the reason?

    Perhaps for some reason the console has already been initialized earlier. For example, you have already tried to bring something into it. Or simply looked in the debugger property Console.Out .

    In order to re-initialize the console - you can use two methods.

    Method one - manually:

     Console.SetOut(new StreamWriter(Console.OpenStandartOutput(), Console.OutputEncoding));

    Method two is to change the console encoding:

     Console.OutputEncoding = Console.OutputEncoding;
    • It did not help. I will try to explain in more detail. There is a WinForms application, the console is invoked in it with the help of p \ invoke. The problem takes place only when starting / debugging from the studio. - User12983791
