Issues getting a 2010 VSTO outlook plugin working on Outlook 2013?

Question

I have an outlook plugin built with Visual Studio 2010 (.net 4.0 Client Profile), that works fine in Outlook 2007 and Outlook 2010. I just tested on 2013 and even installing the addin seems to crash. After googling, I see a few examples of issues people have faced but fundamentally can't get a straight answer to this question:

Is there any prerequisite that would not allow a VS 2010 Outlook addin to just work on 2013 or do I need to upgrade Visual Studio and Create an Outlook 2013 specific version of my addin?

Answer 1

The Running Solutions in Different Versions of Microsoft Office article describes all details. It states the following:

If you developed solutions for Office 2010, you can run the same solutions in Microsoft Office 2013. Solutions that were created by using Visual Studio 2013, Visual Studio 2012 or Visual Studio 2010 can run in Office 2013, Office 2010, or the 2007 Microsoft Office system.

What is the target .Net framework of your add-in? Did you try to debug the code? Do you get any exceptions?
