The VSTO loader for managed add-ins for Outlook fixes a number of issues. Yes it provides a project template and an surfaces the Outlook OM to intellisense. It also fixes a number of important "plumbing" issues:
The loader is signed so that you can set the Outlook security mode to "highest". Only add-ins that fail are blacklisted, not all of the unmanged add-ins. Each add-in runs in its own appdomain. The loader correctly handles the shutdown of the add-in. The add-in is surfaced in the "COM Add-ins" UI in outlook, so that you can managed your add-ins, Enable/Disable or remove. You no longer need to create a unmanged shim.
Thanks
