I've had a few of these recently. Looking in the ActivtyLog.xml, I see an error entry like this...

System.NullReferenceException: Object reference not set to an instance of an object. at Microsoft.VisualStudio.Language.Intellisense.AsyncCompletion.Implementation.AsyncCompletionBroker.IsCompletionActive(ITextView textView) at Microsoft.VisualStudio.Language.Intellisense.Implementation.CompletionBroker.GetSessions(ITextView textView) at Microsoft.Html.Editor.Completion.HtmlCompletionController.OnTreeUpdateCompleted(Object sender, HtmlTreeUpdatedEventArgs e) at System.EventHandler`1.Invoke(Object sender, TEventArgs e) at Microsoft.Html.Editor.Tree.HtmlEditorTree.FireOnUpdateCompleted(TreeUpdateType updateType, Boolean fullParse) at Microsoft.Html.Editor.Tree.TreeUpdateTask.ProcessComplexChange(TextChangeContext context) at Microsoft.Html.Editor.Tree.TreeUpdateTask.ProcessChange(TextChangeContext context) at Microsoft.Html.Editor.Tree.TreeUpdateTask.OnTextChanges(List`1 textChanges) at Microsoft.Html.Editor.Tree.HtmlEditorTree.OnTextBufferChanged(Object sender, TextContentChangedEventArgs e) at Microsoft.VisualStudio.Text.Utilities.GuardedOperations.RaiseEvent[TArgs](Object sender, EventHandler`1 eventHandlers, TArgs args) --- End of stack trace from previous location where exception was thrown --- at Microsoft.VisualStudio.Telemetry.WindowsErrorReporting.WatsonReport.GetClrWatsonExceptionInfo(Exception exceptionObject)

Anyone know what might be causing this?

VS017 Enterprise, Win7 64-bit Pro
