I have a couple of Excel Add ins. If I move to Office 365, will these add ins be available ? Is there any development support(VSTO) for Office 365 ?

I to have been curious about the answer to this, so went looking online. From the following site, I’d say the answer is no. It looks like developing for Office 365 is more along the lines of SharePoint development.

I have seen advertisements online for products such as this… http://www.ocxt.com/products that look like they could provide a possible solution for taking a vsto application to the web.
