What is VSTO?

VSTO, with its clear name Visual Studio Tools for Office, is a technology that enables us to make more professional looking and more performance add-ins compared to Excel Add-ins by taking advantage of the .Net framework. You must be knowing three types of add -ins. VSTO add-ins are also known as COM Add-ins, if you are not familiar with javascript, they are the last point you should come to. However, if you want to see the differences between the state-of-the-art web add-ins and VSTO, there are lots of comparison pages on the net.
