To create a new Excel VSTO Add-in project in Visual StudioStart Visual Studio. On the File menu, point to New, and then click Project. In the templates pane, expand Visual C# or Visual Basic, and then expand Office/SharePoint. Under the expanded Office/SharePoint node, select the Office Add-ins node.
