I have to use a serial port that is shared across two UIs in C# .NET 4.5

I have a C# application that opens up two GUIs at startup. One of the GUI opens three virtual COM Ports. I want the other GUI that is a part of the same application to show the data that is being sent on those virtual COM Ports. Is there anyway to share this COM Port declaration that I do in the Main/First GUI that I am opening up.

Three ways:

1) Copy the instance of the connection from Window1 to Window2.

window2.Connection = this.Connection;

2) Make it the connection a public static member

class Window1 : Window
{
   public static SerialConnectionClass Connection { get; set; } = new SerialConnectionClass();
}

You can access the connection like that:

class Window2 :Window
{
...
   private void func()
   {
      Window1.Connection.Send("");
   }
}

3) Make a static ConnectionManager

static class ConnectionManager
{
    public static SerialConnectionClass Connection { get; set; } = new SerialConnectionClass();
    public static EventHandler MessageReceived;
    public static void Send(string text)
    {
        Connection.Send(text);
    }
    ...
}

Use it in Window1 and Window2 like this:

class Window2 :Window
{
...
   private void func()
   {
      ConnectionManager.init("COM1");
      ConnectionManager.MessageReceived += this.MessageReceived;
      ConnectionManager.Send("test123");
   }
}
