To hide a Console Window in C# and VB.NET you can use the following snippet.

Sample C#

public static class Consoles
{
	[DllImport("user32.dll")]
	public static extern IntPtr FindWindow(string lpClassName, string lpWindowName);

	[DllImport("user32.dll")]
	public static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);

	public static void SetConsoleWindowVisibility(bool visible, IntPtr hWnd)
	{
		ShowWindow(hWnd, !visible ? 0 : 1);
	}
