Access main window label from a separate project avoiding circular references C#-WPF

I had 2 projects in one solution. Project 1 needs a class from project 2 and project 2 needs a class of project 1.

The problem is: If I add a reference of project 1 in project 2, I cannot add a reference of project 2 in project 1 .
But I needed to access main window's label from different project class. This is how I achieved it

	public class ClassfromProject2
	{
	public static event Action<string> MessageReceived;
	// calling the message displayer
	public ClassfromProject2()
	{
	Broadcast("this is the sample message");
	}
	internal static void Broadcast(string message)
	{
	if (MessageReceived != null)
	{
	MessageReceived(message);
	}
	}
	}

Presentation project:

	Using Project2;
	public partial class MainWindow : Window
	{
	public MainWindow()
	{
	InitializeComponent();
	ClassfromProject2.MessageReceived += messagetext =>
	{
	status_lable.Content = messagetext;
	};
	}
	}
