Visual Studio MEF Extension - Force Margin Glyphs To Be Updated or Redraw

Question

The extension I am writing started life from the Walkthrough: Creating a Margin Glyph example provided by Microsoft: https://msdn.microsoft.com/en-us/library/ee361745.aspx

Answer 1

You were on the right path, changing from ITaggerProvider to IViewTaggerProvider allowed me to redraw the glyphs. I used the Implementing a Brace Matching Tagger Provider section in Walkthrough: Displaying Matching Braces example to make these changes.

Using the IViewTaggerProvider, you can then call

TagsChanged?.Invoke(this, new SnapshotSpanEventArgs(
                              new SnapshotSpan(
                                      SourceBuffer.CurrentSnapshot,
                                      0, 
                                      SourceBuffer.CurrentSnapshot.Length)));

in your functions to explicitly call GetTags and go over the spans in the current snapshot.
