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 and the code is not syntax highlighted. What steps am I missing to make this a full fledged editor?

Code:

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

    TextReader reader = new StreamReader(fileName);

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

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

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