Use a shared library to migrate your Visual Studio Tools for Office add-in to an Office web add-in
Visual Studio Tools for Office (VSTO) add-ins can only run in Office on Windows. By migrating your code to an Office web add-in, you can expand the reach of your add-in to mobile and online platforms. Migrating the code will involve rewriting it in the JavaScript language, and also updating it to use the Office JavaScript APIs.
