To fix the issue you can do Using arrays in XAML is quite simple: first you declare your margins array as a public property of your Window:
public Thickness[] MyArray { get; set; }
MyArray = new Thickness[50];
MyArray[0] = new Thickness(5, 5, 5, 5);
MyArray[1] = new Thickness(10, 10, 10, 10);
// ...
DataContext = this;
<TextBox x:Name="TextBox1" Margin="{Binding MyArray[0]}" />
<TextBox x:Name="TextBox2" Margin="{Binding MyArray[1]}" />
public ObservableCollection<Thickness> MyCollection { get; set; }

public MainWindow()
{
    InitializeComponent();

    MyCollection = new ObservableCollection<Thickness>();
    MyCollection.Add(new Thickness(5, 5, 5, 5));
    MyCollection.Add(new Thickness(10, 10, 10, 10));
    // ...
    DataContext = this;
}
<TextBox x:Name="TextBox1" Margin="{Binding MyCollection[0]}" />
<TextBox x:Name="TextBox2" Margin="{Binding MyCollection[1]}" />

create X.xaml and X.xaml.cs files vs should understand they are xaml and code behind

will be helpful for those in need This is because Visual Studio doesn't know they are associated. It's just a naming convention to have .xaml and .xaml.cs. IN the project file you need to enforce the relationship via:
<Compile Include="NodeControl.xaml.cs">
  <DependentUpon>NodeControl.xaml</DependentUpon>
</Compile>

Merge XAML file into Xaml code

this will help I want to merge one XAML file, that only contains styles into the Window.Resource of my application. I tried using MergedDictionaries as described in WPF Reference custom resource defined in another xaml file . , Here is a demo wpf project:
-WpfApplication
 |--App.xaml
 |--MyStyle[here is a floder]
   |---MyStyleDocument1.xaml
   |---MyStyleDocument2.xaml
   |---MyStyleDocument3.xaml
 <Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
              <!--add style file here like this-->
              <ResourceDictionary Source="/MyStyle/MyStyleDocument1.xaml" />
        </ResourceDictionary.MergedDictionaries>
    <ResourceDictionary>
 <Application.Resources>

How are XAML elements accessed from code behind in a different XAML file?

I think the issue was by ths following , What are you trying to do here? The code you posted has got nothing to do with accessing "XAML objects in another file". The Application.Properties property is just a dictionary for sharing data, in a thread-safe fashion between different parts of your application. It is very rarely used in my experience - in fact I have never seen it used. You are getting a null exception because you probably haven't added the 'favoritesItem' to the dictionary first.
If you want to access a named XAML element from another class you will need to expose it via a public property. (Named XAML elements create private member fields in their defining class).

Loading a grid in xaml code from a file, then making it active in main code

I wish this helpful for you A really simple solution would just be to house each of your rooms inside a user control and then place the control into your container grid when you need to change rooms. Here's the rough idea:
public partial class MainWindow : Window
{
    UserControl _currentRoom;  

    public MainWindow()
    {
        InitializeComponent();
    }

    protected override void OnPreviewMouseDown(MouseButtonEventArgs e)
    {
         this.areaContainer.Children.Clear();
         _currentRoom = null;

        if (e.LeftButton == MouseButtonState.Pressed)
            _currentRoom = new Room1(); 
        if(e.RightButton == MouseButtonState.Pressed) 
            _currentRoom = new Room2(); 

        this.areaContainer.Children.Add(_currentRoom); 
        base.OnPreviewMouseDown(e);
    }

}
<UserControl x:Class="Test.Room1"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
         xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
         mc:Ignorable="d" 
         d:DesignHeight="300" d:DesignWidth="300">
    <Button Height="100" Width="100">
        Hello world!
    </Button>   
</UserControl>

Use UIElement from XAML file in a window's XAML code

Hope this helps
You may perhaps bind the Content property of a ContentControl, with a Binding Converter that returns the result of XamlReader.Load.
