[RESOLVED] VSTO Plugins Being Disabled During Debug

[Shaggy Hiker]

I haven't delved into this one well enough, but then again, I'm not quite sure where to look.

I'm working on developing a VSTO plugin. Word is auto-disabling it. I have to go into the Options and re-enable it, after which it works fine a far as I can see, except that every time I try to test something, Word objects that it's running into problems with the plugin and asks me if I want to disable it.

The thing is that this plugin is as generic as any can get. The plugin is only adding a button onto a menu. Everything else happens when the button is plugged. That means that the ONLY code prior to the button press is the boilerplate methods that MS added to the project (which have no bodies), and this one:

 Protected Overrides Function CreateRibbonExtensibilityObject() As Microsoft.Office.Core.IRibbonExtensibility

        Return Globals.Factory.GetRibbonFactory().CreateRibbonManager(New Microsoft.Office.Tools.Ribbon.IRibbonExtension() {New LaunchButton()})

    End Function

The launch button has no custom constructor, nor anything in it's Load method, only in it's Click method, so there really is no code that could be causing the plugin to have trouble.

I found one thing that suggested that it might be throwing an exception when there is no document present, so I changed that, but that didn't quite improve the situation (and some people might find it annoying).

Does anybody have any suggestions as to what I should look at next?
