How to run WPF application from console?

Question

WPF

Good afternoon.
What is available:

• One Solution
  
• There are two projects in it. One of which is console, the other is WPF
  

It is required to run the WPF application in a new thread from the console.
I found a way on the Internet through System.Windows.Application, but this does not exist.
Then in the WPF application I created a new method, so to speak, the main one.
And ran it in a new thread like this:

// Наш класс WPF приложения.
    MainWindow WPF = new MainWindow();
    Thread WPFTh = new Thread(new ThreadStart(WPF.MainWindows));
    WPFTh.Start();  // Запускаем поток

In this method (the main one), the components are initialized, as in the constructor of a regular WPF application. But nothing happens. The application does not start.
What's the trouble?
--ADD--:
Tried using the show method to open the window in a new thread.

MainWindow WPF = new MainWindow();
Thread WPFTh = new Thread(new ThreadStart(WPF.Show));
WPFTh.Start();

But the following error pops up:
"An unhandled exception of type 'System.InvalidOperationException' in WindowsBase.dll
Additional information: The calling thread cannot access this object because another thread is the owner of this object."
Opened without a new stream. The console works, but the window doesn't. It opened, but it remains to hang not working.

using System;

class Program
{
    [STAThread]
    static void Main(string[] args)
    {
        Console.WriteLine("Starting WpfApplication1.exe...");

        var domain = AppDomain.CreateDomain("WpfApplication1Domain");
        try
        {
            domain.ExecuteAssembly("WpfApplication1.exe");
        }
        catch(Exception ex)
        {
            Console.WriteLine(ex.ToString());
        }
        finally
        {
            AppDomain.Unload(domain);
        }

        Console.WriteLine("WpfApplication1.exe exited, exiting now.");
    }
}
