title: C# redirecting data to an already running console exe
body: <p>What I want todo:</p>
  
  <p>I want to start a built console application (AppB) from within another console application (AppA). AppA starts AppB without any arguments. All AppB does is to go into its <code>Main()</code> Method and call <code>Console.ReadLine()</code>.</p>
  
  <p>Now I want that AppA sends a string of data over to AppB's <code>Console.ReadLine()</code>. Is this even possibel? (I know I can send streams to a new Console.exe but that's not what I need.)</p>
