Custom Tool: Hosting an editor (IWpfTextViewHost) in a tool window

I'm trying to host a IWpfTextView within a custom tool window. My project is facing the exact same issue as this one: http://social.msdn.microsoft.com/Forums/en/vsxprerelease/thread/5baa6ad8-9730-4e20-b93e-1b88a8ff1cf4

I'm trying to create a IWpfTextView and then put it into a custom tool window. I can create the view, read a file to populate the ITextBuffer and display the view into my tool.

I cannot edit the code at all, the code is not syntax highlighted and I do not get a context menu on right-click. What steps am I missing to make this a full fledged editor?

Here is my code:

    IComponentModel componentModel =(IComponentModel)GetGlobalService(typeof(SComponentModel));
    var _textEditorFactoryService = componentModel.GetService<ITextEditorFactoryService>();
    var _textBufferFactoryService = componentModel.GetService<ITextBufferFactoryService>();
    var _contentTypeRegistryService = componentModel.GetService<IContentTypeRegistryService>();

    TextReader reader =newStreamReader(fileName);

    var types = _contentTypeRegistryService.GetContentType("CSharp");

    ITextBuffer textBuffer = _textBufferFactoryService.CreateTextBuffer(reader, types);
    var view = _textEditorFactoryService.CreateTextView(textBuffer);

    IWpfTextViewHost editor = _textEditorFactoryService.CreateTextViewHost(view,true);

I'm using Visual Studio 2010 RC, C#
