You can still use  Background  as the property name  as long as you give your window a name and use this name on the  Source  of the Binding

Here you ve got a copy-paste code   class NameToBackgroundConverter   IValueConverter               public object Convert object value  Type targetType  object parameter  CultureInfo culture                        if value ToString       System                                 return new SolidColorBrush System Windows Media Colors Aqua                else                               return new SolidColorBrush System Windows Media Colors Blue                                    public object ConvertBack object value  Type targetType  object parameter  CultureInfo culture                        return null

Important    Make sure you re using System Windows Media Brush and not System Drawing Brush  They re not compatible and you ll get binding errors    The color enumeration you need to use is also different     System Windows Media Colors Aquamarine   class name is Colors      lt --- use this one      System Drawing Color Aquamarine   class name is Color    If in doubt use Snoop and inspect the element s background property to look for binding errors - or just look in your debug log

I figured this out  it was just a naming conflict issue  if you use TheBackground instead of Background it works as posted in the first example  The property Background was interfering with the Window property background

I recommend reading the following blog post about debugging data binding  http   beacosta com blog  p 52  And for this concrete issue  If you look at the compiler warnings  you will notice that you property has been hiding the Window Background property  or Control or whatever class the property defines

The Background property expects a Brush object  not a string  Change the type of the property to Brush and initialize it thus   Background   new SolidColorBrush Colors Red

User · Answer

You assigned a string  Red   Your Background property should be of type Color   using System Windows  using System ComponentModel   namespace TestBackground88238       public partial class Window1   Window  INotifyPropertyChanged                 region ViewModelProperty  Background         private Color  background          public Color Background                       get                               return  background                             set                                background   value                  OnPropertyChanged  Background                                     endregion                      Then you can use the binding to the SolidColorBrush like this   public Window1         InitializeComponent        DataContext   this       Background   Colors Red      Message    This is the title  the background should be     Background toString               not 100  sure about the  toString   method on Color-Object  It might tell you it is a Color-Class  but you will figur this out
