I have been working on an Outlook addin developed with a VSTO designer. The
application has been working great for about 5-6 months now. Unfortunately,
a problems seems to have developed some time since my last release. Now,
when I install the latest version of the application (even on my development
machine), it causes Outlook to crash. If I run the application from the VS
debugger, it works FINE. Because it never crashed while I was debugging, I
have done a considerable amount of work since the last stable version, so the
question "what changed" is difficult to answer. Quite a lot has changed.
Any suggestions about what might cause this behavior, or what I can do to
isolate it?
