First of all, it does support it. Second of all, you should not put data in XAML. Add the objects you want from your data using your code or binding. Read about binding; eventually, with XAML, you will have to use it.

Do you mean a static resource? This would be declared in XAML (though this is bad from maintainability and extensibility aspects...)

Anyways, if you are looking for static resource then,

C#

// 1. In your Window tag declare usage of .NET System namespace

  <window x:class="WpfTutorialSamples.WPF_Application.ExtendedResourceSample" xmlns:x="#unknown">
          xmlns="http://schemas.microsoft.com/winfx/2010/xaml/presentation"
          xmlns:x="http://schemas.microsoft.com/winfx/2010/xaml"
          xmlns:s="clr-namespace:System;assembly=mscorlib"
          Title="StaticResourceComboboxSample" 
          Height="400"
          Width="300">

// 2. Now, namespace alias 's' corresponds to System namespace in mscorlib.dll and this has the standard types defined.

// 3. Create a static resource, it has a key property which will be used later to use/associate this resource to a control e.g. combo-box in your case.

  <x:array x:key="CBXDropdownItems" type="s:String">
    <s:string xmlns:s="#unknown">A</s:string>
    <s:string xmlns:s="#unknown">B</s:string>
    <s:string xmlns:s="#unknown">C</s:string>
  </x:array>

// 4. Now all we have to do is associate this resource (key) to the control's data source (ItemsSource property).

  <combobox itemssource="{StaticResource CBXDropdownItems}" /></window>
