I know I can declare an array of string in XAML like this:

<x:Array Type="{x:Type System:String}">
   <System:String> first </System:String>
   <System:String> second </System:String>
   <System:String> third </System:String>
</x:Array>

How can I declare an array of System.Collections.Specialized.StringDictionary in XAML

<x:Array Type="{x:Type Specialized:StringDictionary}">
    <Specialized:StringDictionary>
        (((what do I put here?)))
    </Specialized:StringDictionary>
</x:Array>

Thanks!

    No built in way to support it but two options to get you close.

    If you are on .NET 4 and are NOT compiling your XAML (highly unlikely)
    you can do something like this

    Again, this is really not a viable solution for most but it is possible.

    More than likely you will want to create a custom markup extension to support generic collection initialization. Something like this:

    adapt his last solution to include key and value and it should get where you want, sort of
