VS.NET 2013 crash on building a WIX project

I was having an issue where building my WIX projects caused Visual Studio to crash. I opened up the Visual Studio activity log located at %APPDATA%\Microsoft\VisualStudio\11.0\ActivityLog.xml

Saw the following error –

System.NullReferenceException: Object reference not set to an instance of an object. at Microsoft.VisualStudio.Debugger.Parallel.UI.ThreadMarkerGenerator.LocationMatchesTagger(DocumentContext location, MarkerTagger tagger) at Microsoft.VisualStudio.Debugger.Parallel.UI.ThreadMarkerGenerator.<>c__DisplayClass1.<GetMarkersForTagger>b__0(ThreadMarker marker) at System.Linq.Enumerable.WhereListIterator`1.MoveNext() at Microsoft.VisualStudio.Debugger.Parallel.Extension.MarkerTagger.<GenerateTagList>d__a.MoveNext() at System.Linq.Buffer`1..ctor(IEnumerable`1 source) at System.Linq.Enumerable.ToArray[TSource](IEnumerable`1 source) at Microsoft.VisualStudio.Debugger.Parallel.Extension.MarkerTagger..ctor(ITextBuffer buffer, ITextDocument document) at Microsoft.VisualStudio.Debugger.Parallel.Extension.MarkerTaggerProvider.CreateTagger[T](ITextBuffer buffer) at Microsoft.VisualStudio.Text.Tagging.Implementation.TagAggregator`1.GatherTaggers(ITextBuffer textBuffer)

It helpfully also said that the source of the error was ‘Editor or Editor Extension’. That was good, because the stack trace wasn’t very revealing.

Luckily, I don’t have a ton of extensions and the culprit turned out to be the Code Digger extension.

Googling/ binging didn’t help very much, although apparently there is a known cause that causes the same crash, more details at http://channel9.msdn.com/Forums/Feedback/Having-both-Wix-and-Visual-Studio-Achievement-causes-crash
