Question

Strange exception happens when I work in VS 2010. I’m creating web project and insert button. When I double click on the button to create onClick event, I get a message box from Visual Studio which says: “visual studio has encountered an exception. this may be caused by an extension. You can get more information by running the application together with the /log parameter on the command line, and then examining the file”

When I do that in cmd, it creates an ActivityLog file which has a few tags like this one:

<description>
    System.ObjectDisposedException: Cannot access a disposed object.&#x000D;&#x000A;Object name: &apos;TagAggregator&apos;.&#x000D;&#x000A;
        at Microsoft.VisualStudio.Text.Tagging.Implementation.TagAggregator`1.&lt;GetTags&gt;d__e.MoveNext()&#x000D;&#x000A;   
        at RemObjects.Oxygene.VisualStudio.Editor.MessageHighlightAdornmentManager.TextBuffer_Changed(Object sender, TextContentChangedEventArgs e)&#x000D;&#x000A;
        at Microsoft.VisualStudio.Text.Utilities.GuardedOperations.RaiseEvent[TArgs](Object sender, EventHandler`1 eventHandlers, TArgs args)
</description>

What does that mean?

Answer 1

That means that an extension that uses RemObjects.Oxygene has a bug.
