Is it possible to include Outlook web AddIn into VSTO AddIn?

I'm new to development in Microsoft Office AddIns. I created one Outlook Web AddIn with javascript/html/css. Is it possible to create one Outlook VSTO AddIn, with a button for example, that opens the Web AddIn?

Solution

No, it is not possible. OfficeJS or VSTO (nor the Outlook extensibility model) doesn't provide any API for that.
