Remarks

This attribute is used at the assembly level to indicate which theme resource dictionaries are being declared by an assembly for its defined controls, and where the resource dictionaries are located.

For example, if you do not provide theme-specific resource dictionaries, and your generic.xaml that supplies resource definitions for all resource lookups is compiled into the same assembly in which the assembly's control class definitions exist, you would apply the following attribution in the AssemblyInfo.cs for the assembly project:

[assembly:ThemeInfoAttribute(ResourceDictionaryLocation.None, ResourceDictionaryLocation.SourceAssembly)]

In addition to ThemeInfoAttribute application, your project and assembly must have additional characteristics in order for the resource dictionaries to be usable by the WPF theming system.

• If you declare SourceAssembly, then the referenced resource dictionary should be placed within a themes directory in the assembly structure.

• If you declare SourceAssembly for ThemeDictionaryLocation, then the names of the XAML files are expected to conform to the XAML file naming scheme themes\<Theme Name>.<Theme Color>.xaml. For example, the following is a list of theme files that support a variety of possible WPF theming scenarios on clients:

  • themes\luna.normalcolor.xaml

  • themes\luna.homestead.xaml

  • themes\luna.metallic.xaml

  • themes\royale.normalcolor.xaml

  • themes\aero.normalcolor.xaml

  • themes\classic.xaml

• If you declare ExternalAssembly, then the external assembly names are expected to conform to a naming scheme, and each assembly for each theme should be built using the same key information.
