A minimal implementation of `IVsLanguageInfo`

ExampleLanguageInfo.cs

using System;
using System.Runtime.InteropServices;
using Microsoft.VisualStudio;
using Microsoft.VisualStudio.TextManager.Interop;

[Guid("your guid here")]
internal class ExampleLanguageInfo : IVsLanguageInfo
{
    public int GetCodeWindowManager(IVsCodeWindow pCodeWin, out IVsCodeWindowManager ppCodeWinMgr)
    {
        ppCodeWinMgr = null;
        return VSConstants.E_NOTIMPL;
    }

    public int GetColorizer(IVsTextLines pBuffer, out IVsColorizer ppColorizer)
    {
        ppColorizer = null;
        return VSConstants.E_NOTIMPL;
    }

    public int GetFileExtensions(out string pbstrExtensions)
    {
        pbstrExtensions = ".e1;.e2";
        return VSConstants.S_OK;
    }

    public int GetLanguageName(out string bstrName)
    {
        bstrName = "Example";
        return VSConstants.S_OK;
    }
}

Hi Sam, I see that GetColorizer is not being implemented (I see the same thing in Python Tools). What class is now doing the job of the IVsColorizer object?
