(C#) How to know if a key is held down in .NET Console Application

I want to know, if a key is held down by the user. I know how to do that in WinForms, but no clue in Console App. I don't want to download any C++ libraries or anything. Just want to know if you can do that using the System namespace.

So, as you know, Console.ReadKey() stops the application until a key is pressed. I tried doing Console.KeyAvailable && Console.ReadKey(true).Key == ConsoleKey.Escape in an if statement (of course I also used else after that to change things back to false). It worked at first glance, but there is an obvious lag between key press and the reaction.
I would appreciate any help.

This can be achieved using a "while" statement.
For example:

while (Console.ReadKey().Key == ConsoleKey.Escape)
{
    Console.WriteLine("Hello, World!");
}
