How to get Current ActiveDocument in Visual Studio Extension using MEF?

Question

I\'m working on Visual Studio 2013 Extension using MEF while trying to read Active Document Content Type and Code. Presently it only reads at Opening Time of the Document/Pr

Fortunately, I got what I was trying to achieve. A helper solution is already posted here: I used the helper method in dte2.Events.WindowsEvents.WindowActived and getting IVsTextView object to retrieve the Text Buffer. Here is my Code snippet of WindowActivated event:

void WindowEvents_WindowActivated(EnvDTE.Window GotFocus, EnvDTE.Window LostFocus)
    {

        if (null != GotFocus.Document)
        {
            Document curDoc = GotFocus.Document;
            Debug.Write("Activated : " + curDoc.FullName);
            this.IvsTextView=GetIVsTextView(curDoc.FullName); //Calling the helper method to retrieve IVsTextView object.
            if (IvsTextView != null)
            {
                IvsTextView.GetBuffer(out curDocTextLines); //Getting Current Text Lines 

                //Getting Buffer Adapter to get ITextBuffer which holds the current Snapshots as wel..
                Microsoft.VisualStudio.Text.ITextBuffer curDocTextBuffer = AdaptersFactory.GetDocumentBuffer(curDocTextLines as IVsTextBuffer); 
                Debug.Write("\r\nContentType: "+curDocTextBuffer.ContentType.TypeName+"\nTest: " + curDocTextBuffer.CurrentSnapshot.GetText());

            }
        }
    }

This is now working with all the code documents opened in VS Editor. Hope this would help others like me.
