I want to create some UI in MS Office apps in Windows OS (mostly Word, Excel, Powerpoint). The UI can be a task pane. Minimum i have to support MS Office version 2016. If its support MS Office 2007, 2010, 2013 too, it is well and good. First i am doing for Windows OS. If its supports Mac OS too, it is well and good.
I need to use some programming language independent of any dependencies. Also i need a resultant file which can be installed on any user machine. For ex: a dll file which can be installed and registered on any user machine using an installer. I want anyone in the world can download my installer and install and use my app.
(ii) VSTO Add-in seems to have .NET and VSTO runtime dependencies. I don't like to ask the users to install the dependencies.
I came to know about C++ COM Add-in but i don't get enough documentation to do it.
Kindly provide solution asap.
