generic.xaml

In WPF it was possible to organise the XAML for multiple user controls by keeping the markup in separate XAML files in the themes folder and then using MergedDictionaries to import them into generic.xaml: <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="MyFirstControl.xaml" /> <ResourceDictionary Source="MySecondControl.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> With the availability of the Silverlight 3 beta introducing merged dictionary support, it seemed like it might be possible to do the same with Silverlight user

I made a class library assembly in which I created custom controls, and I defined the default styles in the generic.xaml file. It seems this is a quite common problem, as long as many people are posting about it. However I couldn't find any useful answer for my case. the generic.xaml is in the Themes folder. the generix.xaml file Build Action is set to Page. the ThemeInfo is properly defined in my AssemblyInfo.cs. In my test application, if I manually merge the generic.xaml file from my custom controls assembly into the application App.xaml file like this: <Application.Resources>

Themes\Generic.xaml: <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="WPF Commons;component/Controls/Layout/Foo/FooItem.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> Controls\Layout\Foo\FooItem.xaml: <Style TargetType="{x:Type l:FooItem}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type l:FooItem}"> <Border> <ContentPresenter ContentSource="Header" /> </Border> <
