Expose public Microsoft.VisualStudio.LanguageServices IOLECommandTarget for command routing


I've been working on adding various C# language services to a projection buffer. I'd like to add the proper language services to the command chain.

Microsoft.VisualStudio.LanguageServices defines an internal AbstractOleCommandTarget which may be attached to IWpfTextViews.

If I were able to inherit from AbstractOleCommandTarget, I could properly set up the proper language services myself. I've already tested out a proof of concept in which I manually edited Microsoft.VisualStudio.LanguageServices.dll's "InternalsVisibleTo" property within the DLL. This allowed me to inherit from AbstractOleCommandTarget and properly set up Intellisense within the Visual Studio command chain.

Usage would be as follows:
class CustomOleCommandTarget : AbstractOleCommandTarget
    public CodeConnectOleCommandTarget(IWpfTextView textView
        ,ICommandHandlerServiceFactory commandFactory
        ,IVsEditorAdaptersFactoryService adapterFactory
        ,IServiceProvider provider) :base(textView, commandFactory, adapterFactory, provider)

public void AttachToIWpfTextView(IWpfTextView textView)
    var commandTarget = new CodeConnectOleCommandTarget(
                , this._commandFactory
                , this._editorFactoryService
                , this._serviceProvider);

This would also let me get rid of this utter horror (and key strokes for non-VS hosting.

Want to re-file this over on GitHub, and consider a PR for it?
