Notepad++ User Defined Language in Visual Studio

I'd like to use my userdefinedlanguage.xml files from Notepad++ in Visual Studio. How do I export classifiers at runtime?

Here is the flow:

1. Visual Studio starts
2. UDLPackage starts
3. UDLPackage loads my *.xml files
4. UDLPackage creates a UDLClassifierProvider for each *.xml file
5. UDLPackage exports the UDLClassifierProvider with the Name, ContentType, FileExtension specified in each xml file.

    [Export(typeof(ITaggerProvider))]
    [ContentType("ook!")]
    [TagType(typeof(ClassificationTag))]
    internal sealed class OokClassifierProvider : ITaggerProvider
    {

        [Export]
        [Name("ook!")]
        [BaseDefinition("code")]
        internal static ContentTypeDefinition OokContentType = null;

        [Export]
        [FileExtension(".ook")]
        [ContentType("ook!")]
        internal static FileExtensionToContentTypeDefinition OokFileType = null;

I can do steps 1 through 4. How do I do step 5? How do I programatically export my UDLClassifierProvider with MEF at runtime.
