Those of you who have been following my blog will note that I have retroactively added some categories. I hadn't bothered with categories in the past because almost all of my posts have been about MAF.
Well, now that MAF is a real thing, we (meaning my team here at MS) are actively building two products upon its foundations: VSTO and VSTA. In fact, going forward VSTO can be thought of as an Office specific specialization of VSTA.
I will be blogging more on these two products as time goes on, so it seemed prudent to categorize.
(BTW: VSTO = Visual Studio Tools for the Microsoft Office System, VSTA = Visual Studio Tools for Applications)
